"can you listen to the tv with the mx w1" and "can i watch tv with kleer" responses

Two people visited this blog recently using Google keyword searches of:
  • can you listen to the tv with the mx w1
  • can i watch tv with kleer
Yes to both but with qualifications:

The Sennheiser MX W1 true wireless earbuds do have a low latency as they use Kleer wireless audio technology. However, the latency is not quite low enough so that you can watch TV and not have lip-synch issues. The latency is needed in case the MX W1 needs to switch to a different band in the 2.4 GHz channel and not have the music drop. Now, the lip-synch is minor and may not bother everyone. However, just to be warned, they weren't designed for watching TV or videos off your laptop; they were designed for listening to music, where there are no lip-synch issues. Again, it may not bother you, but please be aware and purchase them with "eyes open" if you know what I mean. 

Now, the Kleer-based Sennheiser RS 160, RS 170, or RS 180 wireless headphones were designed to be used to watch TV. The latency was specifically lowered so that there are no lip-synch problems when watching TV. 

Here's some recent reviews of the Sennheiser RS 180 wireless headphones from Amazon: 
From the "Great Headphones" December 12, 2010 review:


"These are perfect for listening to TV while others in the house need quiet, plus I can hear the other person talk to me with the open design which I like."

Also from December 12, 2010 some excerpts from a review titled "Outstanding on all fronts":  

"Takes some pretty fancy technology to really impress me these days, and but these headphones are nothing but perfection. I have used high end corded headphones for a long time, and have always preferred Sennheiser. After shopping around for a new pair I finally decided to give the wireless a try. I really did not want to waste a bunch of money for a lesser model so I went all in with the RS 180's and I am truely amazed. Not only do they sound better than my old HD595 pair, the wireless mode is truely the next step in multimedia enjoyment. With a fairly simple set up between my iTunes, Apple TV and an iPod remote I can put the headset on and have perfect high end sound quality at my computer for gaming, then walk away with music playing and then go lounge in bed and watch a streaming movie.

I have watched action movies, played the latest CoD Black Ops and many other games and listen to a wide variety of music and have really found no weak spot as far as sound depth. They exceed any wired headphones I have used for any of the same activities.
"


And as the Sennheiser RS series wireless headphones use Kleer wireless audio technology, this means you hear CD-quality, uncompressed, lossless, digital stereo audio.  Bluetooth compresses audio, which is bad. Kleer lets you hear what the artist/director intended and without the wires.

Arcam rCube review on Pocket-lint: "the rCube’s promise of lossless music streaming dimension is exciting"

Great review of the Arcam rCube on Pocket-lint from November 18, 2010. Read the entire review

My favorite section: "With millions of us having ditched our CD collections this kind of product ought to do well with people searching for a modern Hi-Fi system. Small, perfectly formed and portable, the rCube’s promise of lossless music streaming dimension is exciting and makes the £500 price tag appear good value - this is a pretty serious Hi-Fi component, after all."

Find out the cost of the Arcam rCube on Amazon UK >>


Here's an excerpt: 

"Sick of those £50 iPod docks that spew out meek music? Then try Arcam’s rCube for size; Wi-Fi meets Hi-Fi on this ‘pod-friendly speaker that’s about as high-end as it gets at this size. Ready for more good news? It’s portable. Yup - unplug the 5kg rCube from the mains and its internal Lithium-ion battery will keep going for between 4 and 8 hours. There’s even a grip-hole hidden just behind the iPod dock for carrying the thing around.

The ability to play music from an Apple gadget isn’t exactly new - we’ve seen hundreds before - but the rCube could be about to offer something genuinely new: lossless wireless streaming."

And the lossless wireless streaming is courtesy of Kleer wireless audio. Kleer is not Bluetooth, Bluetooth compresses audio, which is fine when you're talking on the phone. But when you want to listen to music, you want to hear the music the way the musician intended. With Kleer, you hear CD-quality, lossless, uncompressed, digital stereo audio.

There are several ways to enjoy the Kleer wireless sound with the Arcam rCube. It comes integrated in the rCube speaker so that you can pair the speaker with any Kleer-based wireless earbuds or headphones.

Or, you can purchase the separate rWave or rWand dongles. The rWave is USB, allowing you to connect it to your laptop, Windows or Mac. And the rWand dongle is a portable transmitter that you can connect to any compatible iPod/iPhone, allowing you to stream wireless audio from your iPod to the rCube speaker.

Another excerpt:

"Cunningly hidden along the bottom of the rear of the rCube are various ins and outs. A USB port for software upgrades, a power switch and a 3.5mm auxiliary jack to attach almost any audio device are expected. More welcome is a video port that’s capable of taking 720p video from an iPhone 4 (only) to a TV. There’s also a bass button that should be depressed if you use the rCube in the corner of a room."

Arcam also recommends you place the rCube speaker on an angle if you place it in the corner. But I figure you'll figure all that out.

View pricing of the Arcam rCube on Amazon UK >>

Here's an excerpt:

"Inside the cabinet are three amplifiers driving four speakers, two set into each side of the cabinet. That's a combination rated at 90W RMS – 35W from each mid-range driver and 10W from each tweeter – and is enough to fill even a large room with sound.

The rCube’s output has not been achieved at the expense of quality. No matter what I played on it – and I listened to everything from Nine Inch Nails to Carole King, and Tangerine Dream to Tannhauser – the reproduction was always a bright, clear, focused, taught, powerful and superbly detailed sound, that never failed to impress."


"The eagle-eyed amongst you may have noticed the Bass button around the back. These boosters sometimes make everything sound just a little phony and muddy, but not in this case. Press it and the already impressive amount of bass acquires just that extra bit a depth and power, without getting woolly. Yes it's invasive electronic voodoo, but it’s voodoo that works and pays dividends when listening to bass-heavy musical genres."

And the verdict:

"Compared to B&W's Zeppelin or Philips' DS9000 Fidelio, the extra £100 is peanuts when you take into account the increased quality of sound the rCube delivers. Lest we forget forget that it’s also very small, with an internal battery and wireless option. I have to say that, had the rCube been available for inclusion in my up-market iPod dock round-up, it would have taken the gold medal."

And, Kleer wireless audio technology is built into the rCube, meaning it will pair with Kleer-based headphones/earbuds, such as the DigiFi Opera S2, Opera S5, or Sennheiser RS 160, RS 170, or RS 180.

Only issue is that the rWand and rWave dongles cost extra.

But the good news is that the rWand and rWave use Kleer wireless audio technology. Which means that the dongles stream uncompressed, lossless, CD-quality, digital stereo audio. And that works very well with the Arcam rCube's high fidelity sound system where it makes a difference.

Arcam rCube What Hi-fi Sound & Vision 2010 Award Winner for iPod Docks

Congratulations Arcam rCube for winning iPod Docks Product of the Year, Awards 2010!

The award-winning Arcam rCube uses Kleer wireless audio technology to stream your tunes wirelessly when you want to (note, sad to say, the dongles currently cost extra). Otherwise, pop your compatible iPod/iPhone into the dock and control your tunes from it or the remote.

"At first glance, Arcam’s new rCube doesn’t seem like much of a B&W Zeppelin-challenger. At 20cm cubed, it looks almost frivolously small in this assembled company but, as every sensible person knows, size isn’t everything.

Besides, note the price – if that doesn’t put it straight into Zeppelin territory we don’t know what does.

It may have taken Arcam a little while to clamber aboard the speaker/dock bandwagon, but the company’s put that time to good use – the rCube is a thoroughly thought-out device.

On the top, beneath a flush-fitting flap, is the iPod dock (when the dock’s unoccupied the flap serves to reveal a carry-handle – this is a portable device), and some touch-sensitive controls.
Portable iPod powerAt the bottom there are four concealed screws – unscrew these to remove the baseplate and access the pre-installed Lithium-Ion rechargeable battery.

And positioned at the rear is a 3.5mm input, composite video output, component video output (which rather meanly requires a bespoke, extra-cost adaptor), a USB input (for firmware upgrades only) and a power switch.

Oh, and there’s an innocuous-looking button marked ‘bass’. Arcam believes the rCube sounds best placed in the corner of a room, angled at 45 degrees.

Such positioning allows the opposed, side-mounted mid/bass drivers to reflect off the walls  –– if the rCube is sat in open space, give the bass button a push to reinforce those low frequencies. In any event, the rCube can’t be obstructed on either side.

An optional USB transmitter
As well as dealing with docked Apples, the Arcam can stream PC-borne music wirelessly using an optional USB transmitter, or directly from an iPod/iPhone using a Kleer dongle. 

And one rCube can both send and receive to/from a second rCube, so you can establish a multi-zone network with little fuss.

It’s just as well, after that preamble, that the rCube is a fine-sounding device. The proximity of the drivers means it doesn’t so much deliver a soundstage as an omni-directional presentation, but within that it’s mightily impressive.

Whether listening to a 256kbps copy of Elton John’s Take Me to the Pilot or a 1411kbps WAV file of Missy Elliot’s Get Ur Freak On, it’s a clean, balanced and above all informative listen.


Flawless frequency integration

Low frequencies don’t have the outright extension of some rivals, but bass is taut, controlled and nuanced, while the midrange is full of detail. Integration with the open, crisp high frequencies is flawless.

Timing, too, is natural and unforced, so there’s a rare unity to the rCube’s sound. It snaps through dynamic peaks with positivity and deals with the toughest tempos dismissively.

Complex or muddy mixes are confidently unpicked, and the Arcam can turn its hand from a massed orchestral assault to a single-voice-with-guitar without breaking sweat.

In short, it’s everything you want from an iPod speaker dock."

And, Kleer wireless audio technology is built into the rCube, meaning it will pair with Kleer-based headphones/earbuds, such as the DigiFi Opera S2, Opera S5 wireless earbuds, TDK WR700 wireless headphones, or the Sennheiser RS 160, RS 170, or RS 180 wireless headphones.

Only issue is that the rWand and rWave dongles cost extra.

But the good news is that the rWand and rWave use Kleer wireless audio technology. Which means that the dongles stream uncompressed, lossless, CD-quality, digital stereo audio. And that works very well with the Arcam rCube's high fidelity sound system where it makes a difference.

Trusted Reviews investigates the Sennheiser RS 170 wireless headphones

Good thorough review of the Sennheiser RS 170 Kleer-based wireless headphones from March 2010 on the Trusted Reviews website. Does an excellent job of reviewing the RS 170s, and as he's used other wireless audio technology headphones (infrared, FM radio), he has a pretty good idea of what wireless cans should sound like, and not sound like. 

Favorite quote: "It’s no coincidence that several people I know who have become dads in the last few years now swear by their wireless cans. It’s the only way they get to watch the movies they want to watch at the volumes they like to watch them without waking up the kids (or getting an earful from their worn-out other halves)."

I can believe it, especially as the RS 170 wireless headphones are designed for watching the television as the latency is low enough that there is no lip-synch problems. Still, for those who want to use these to play guitar, you will notice the latency. Still, these weren't designed for musicians, but for audiophiles and couch potatoes (especially dads with wee ones) who want to watch their favorite movies or tv shows without the wires. 

Another excellent excerpt: "The closed-back design does a great job of shutting out the outside world, though a small amount of sound leaks out, and also ensures a decent bass response, which you can always beef up with the bass boost. I’ve heard more articulate and well-defined low-ends before, but the RS 170s handled poppy electronic tracks from Royskopp and small group jazz from The Bill Evans trio equally well, and there was no shortage of raunch when I switched to rockier material from Soundgarden, Led Zeppelin and Pearl Jam. The mid-range sounds ever so slightly boxed-in, but there’s plenty of detail there and in the high-end."

So, yeah, higher end, more expensive headphones, you will get full range. But you do have to pay much more for those headphones. And as far as I know, all of those are wired. 

And his closing line: "There’s an awful lot to love about the RS 170s, and very little to dislike. In fact, my one complaint would be that the volume controls are hard to locate by touch alone, and that you have to remove the headphones to change it. This, I think, is pretty small beer, and when set against the excellent sound quality and wireless performance, not worth worrying about. Sure, the RS 170s are three times as expensive as some budget wireless headphones, but to my mind the premium price is just about worth it. Think of them as a long-term investment, giving you your music and movies as you like them, and the rest of your household a spot of peace."

Heard the complaint about the small buttons from other people, but I've also read that you get pretty used to them, so at first it's a hassle, but then becomes a bit of a no-brainer. 

Looks too like they've come down in price. 


And as these wireless headphones use Kleer wireless audio technology and not Bluetooth, you hear uncompressed, lossless, CD-quality digital stereo audio. You can pair these Kleer-based wireless headphones with other Kleer-based transmitters from other manufacturers as well. And up to four people can listen to one transmitter at the same time.

Sennheiser RS 170 wireless headphones and iTunes

Had someone find this blog using the keyword phrase "sennheiser rs170 audio quality with itunes" but then bounced as he couldn't find what he was looking for. Figured this gave me an opportunity to discuss iTunes audio compression (the little I know) and wireless earbuds/headphones that use Kleer wireless audio technology.

Wireless earbuds, wireless headphones, wireless speakers that are built using Kleer technology deliver uncompressed lossless, CD-quality, digital stereo audio. This means you hear what the musician/artist/director (if you're watching TV) intended.

But, and here's the catch, if the music you're listening to is already compressed, then that's what you hear. Now most of the time you might not notice or really care. But when you use Kleer-based wireless earbuds/headphones, you might notice you're missing something, especially if you've heard the songs before on your CD player, so you have something to compare. 

One of my favorite web articles about bit rates is the What does your bit rate say about you? article on the CNET Australia website. Here's some excerpts:

"128kbps
You probably don't know the bit rate at which your music is encoded -- this is the default iTunes rate -- and it seems good to you. You're probably happy with the headphones that came with your MP3 player. But you may have started downloading free music back when Napster was in its original illegal P2P form, and you may currently be a Limewire user, having never heard of or felt the need to understand BitTorrent. You don't see the advantage in hard-disk-based MP3 players and wouldn't know what to listen out for when offered an album encoded in lossless format. You're perfectly happy with having a 2GB MP3 player or an iPod Shuffle. You're unlikely to own a large library of CDs.

So of course the biggest advantage to using the highest (lowest?) compression rate is that you can fit the most songs on your iPod, Touch, iPhone, you get the picture. 

At the other end is lossless compression (as opposed to lossy). So when you rip a song at lossless, the file size is huge. But it is true CD-quality. So when you listen to a ripped song at lossless quality with Kleer based wireless earbuds/headphones, you hear it at true CD-quality. 

Here's how someone is described who likes their songs lossless on the CNET Australia site:

"Lossless (FLAC or Apple Lossless)
You are most likely to be born before 1978. You are the most likely group to be a Mac user and your headphones cost in excess of AU$150, possibly made by Shure, Sennheiser or Ultimate Ears. You own a fifth-gen video iPod and an HDTV. Your laptop cost at least AU$2,500 and you consider yourself a cinema fan. You are the least likely to download music illegally, instead preferring to own a huge CD library. You're highly likely to be a musician and own at least one book about either quantum mechanics, philosophy or psychology. Your mobile phone bill is considerably higher than average and you may work in the technology industry.

You're depressed when you see people on the train using their MP3 player's bundled headphones and you probably listen to technology podcasts. You may well know the bit rate your podcasts are encoded at. You used Napster back in the day, but you never stopped buying CDs. You use Limewire or BitTorrent to occasionally sample an album, but you always buy the CD if you like what you hear.
"

To be perfectly honest, I did rip CDs at the lowest bit rate, then also ripped the same songs at lossless. And using the Sennheiser RS 180 wireless headphones, I could hear a difference. 

So of course you can use the Sennheiser RS 170 wireless headphones with iTunes (you just gotta hook it up properly) and enjoy your music without the wires. But just remember, if you purchase the songs off iTunes, you get the bit rate you purchase at. And if you rip songs using iTunes, you can set the compression rate as low as you want so that you can really get the full benefits of your Kleer-based products. 

One last little bit of of advice. On your iPod / Touch / iPhone / iPad, rip the songs you really want to hear all the finest details at lossless levels. Other songs, rip it at 128. This way, you should be able to fit all your favorite songs on your iPod. Cause really, why do you need 1,000 songs on your device? 



Watch Sennheiser RS 170 wireless headphones turned into outside wireless headphones!

Had somebody hit this blog with the keywords "w-1 Kleer transmitter for RS 170" but then bailed as there was no info (so hard to please everyone). Well, now there is.

I suspect what he was looking for was any information on the ability to pair a Kleer-based transmitter with a different manufacturer's headphones/earbuds. The w-1 is the Sleek Audio wireless kit that turns any Sleek Audio earbuds, even custom ones, into wireless earbuds.

So to prove the point (so imagine the transmitter is the Sleek Audio w-1 transmitter), watch this great video on YouTube demonstrating the interoperability of Kleer-based wireless products.

In this case, pairing the DigiFi S5T transmitter (dongle) made for the iPod/iPhone (make sure it is compatible, check out on the WireFreeHiFi e-commerce website) with the Sennheiser RS 170 wireless headphones. It's a great training video as well, showing you how it's done, and his thoughts about both products.

The video has 4,000+ views and is just a little bit longer than 10 minutes in length, which flies by.

Also, since the video was published, WireFreeHifi has an iPad compatible transmitter.

FREE SHIPPING UNTIL DEC 31, 2010 !!!!! WireFreeHiFi is a UK-based company that ships to North America (States, Canada) and Europe.



DigiFi (a Korean company) first got noticed for its Opera S1 wireless earbuds, which have since been discontinued which is a shame as they had an excellent price point when they were available. Still, the DigiFi Opera S2 wireless earbuds (with universal headphone jack transmitter) and the made-for-iPod Opera S5 wireless earbuds, the upgrades to the S1, make up for it. Even the Sleek Audio wireless kit was designed by DigiFi, with some Sleek Audio upgrades, which is why it looks very similar.

And then DigiFi expanded into making separate transmitters, which you can then associate to other Kleer-based headphones, in this case, turning the Sennheiser RS 170 wireless headphones, ideal for watching television without disturbing anyone, into mobile cans. They also have a transmitter/receiver combo that can turn any iPod-type stereo into a wireless stereo. Check it out!

Purchase the S5T on the WireFreeHiFi website (ships to the USA, Canada, UK, Europe) >>

Almost forgot my usual plug about the awesomeness of Kleer wireless audio technology. Kleer, a proprietary technology delivers uncompressed, lossless, CD-quality, digital stereo audio, a technology feat that Bluetooth can't match.

Using wireless headphones/earbuds based on Kleer technology means you can hear music the way the artist/musician intended, but without the wires.

Opera S5 wireless earbuds for iPad and iPhone: Uses Kleer wireless audio technology


They ship already paired, so all you'll need to do is attached the transmitter to your iPod or iPhone, play your music, and start grooving to your music (if that's your thing). You can purchase them on Amazon UK. They're distributed by WireFreeHifi, who also ship to the States no worries. 

And WireFreeHifi has free shipping until Dec 31, 2010 but I don't know if that applies when you purchase from them via Amazon. So if you want free shipping, you may need to purchase them from WireFreeHifi, who have their own online shopping cart.

Anyhoo, the DigiFi Opera S5 use Kleer wireless audio technology to deliver CD-quality, uncompressed, lossless, digital stereo audio. No Bluetooth, Kleer is not Bluetooth. Kleer is a proprietary wireless audio technology. Bluetooth compresses sound, Kleer does not. So with Kleer, you hear what the artist/musician intended. 

The Opera S5, because it connects using the Apple dock, has volume and track control on the earbuds. This means you can raise/lower audio and pause/start/stop/skip/fast forward/rewind an audio track, all from your earbuds. No need to touch your iPad or iPhone for those controls, it's all with you located conveniently on the wireless earbuds.

Here's some photos of what they look like when you wear them. 

When I used to own a set of the old DigiFi Opera S1s (which they don't make anymore), I used them exclusively for listening to music on my laptop when I was working. I used to actually reverse them so that the receiver that normally sits on the back of your neck, would dangle in front on my chest. Somehow was more comfortable that way for me. So you may also try some different ways of wearing the earbuds, find out what's comfortable for you, what works best.

Review Sennheiser RS 170 Kleer based wireless headphones: "Best audio purchase I made all year"

Another positive review of the Sennheiser RS 170 on Amazon from December 1, 2010.  My favorite line: "Long story short, I would recommend these to anyone that wants a good set of wireless headphones for general use music/movies/games. They are WELL worth the money."  I'm sure a big reason he likes the RS 170 wireless headphones so much is that they use Kleer wireless audio technology, no Bluetooth. Bluetooth compresses audio, which is fine when you're talking on the phone. But when you want to listen to wireless audio, from music to the movie score, you want to hear it how the musician or director intended. And that's where Kleer comes in. Kleer delivers uncompressed, lossless, CD-quality digital stereo audio without the wires.

Here's an excerpt:

"When I finally decided to order some wireless headphones for the living room, I did my research. These were a bit over my target budget at the time, but thanks to the reviews here on Amazon I decided to give them a shot and I am extremely glad that I did.

I ordered this set back in August of 2010, as sort of a birthday present to myself. My wife and I had discussed getting some headphones for the living room so that when I wanted to watch TV or play a louder game at night I wouldn't annoy the neighbors, or her beauty sleep.

I almost immediately decided to look for wireless headphones for the convenience of not having the cord to deal with, or worry about a new kitten chewing through. Also for reasons of convenience, I knew that I wanted a rechargeable set so that I wouldn't have to deal with battery swapping.

My past experiences with wireless headphones were never good as they were fraught with low usage times before needing to be recharged, static from being too far from the receiver or not being 'tuned' to the receiver properly and having to be manually adjusted. I was quite pleased with what I saw when I ran across the Sennheiser RS 170 Digital Wireless headphones, as it seemed like these wouldn't have any of these issues. I am pleased to say that my experience with this set of headphones has been the exact opposite of my earlier experiences; these work fantastically and exactly as advertised."

 
 

Sennheiser RS 170 Kleer-based wireless headphones: "Great sound quality and range and super easy to use!"

Great review on Amazon of the Sennheiser RS 170 Kleer-based wireless headphones from December 4, 2010. And, the author purchased the RS 170 because of Kleer wireless audio technology. Nice, very nice. You see, these headphones, along with the Sennheiser RS 180 and Sennheiser RS 160 and the Sennheiser MX W1 true wireless earbuds do not use Bluetooth. Bluetooth is fine for talking on the phone, not for listening to music or watching television as it compresses audio. And that's not what the musician or movie director intended. Kleer wireless audio delivers uncompressed, lossless, CD-quality, digital stereo audio. You hear what you're suppose to hear, with no hisses or other white noise. You hear what the artist, what the director, what the movie composer wanted you to hear. Couple it with Sennheiser audio technology, it's a win/win. Here's the review:

"I spent a considerable amount of time before deciding on the Sennheiser RS 170 Digital Wireless Headphone. In the end I chose it because of the KLEER Technology and the fact that it had a charging base station (missing in the RS-160) and was not as expensive as the RS-180. The sound quality is great. No disturbance at all. The range is great too. I can listen to the radio or listen to music while moving around our house (2 levels) without any disruption or disturbance. I would highly recommend this product. "

TDK WR700 review wireless headphones: "Recommended!!!"


Some pretty amazing photographs of the TDK WR700 wireless headphones on the TDK website. Only issue is that the info is all in Japanese. Not a problem if you are fluent in Japanese though. The Google translate tool does a decent job of translating. 

Speaking of Japanese websites, there's a positive review of the TDK WR700 on the AV Watch website. On the site, the reviewer also discusses other Kleer-based wireless products.

Kleer wireless audio technology (not Bluetooth) delivers CD-quality, uncompressed, lossless, digital stereo audio. And here's a review of the TDK WR700 wireless headphones from the Amazon UK website:

"I had been thinking about getting a pair of wireless headphones for a while so when these came up, I just had to have them. First of all, setup is a breeze, basically plug and play. You are up and running within seconds. At first I was just using them right next to my PC, which is where I had the wireless transmitter plugged into and the quality is excellent, I don't think you could really tell the difference between wired and wireless unless you were an audiophile and even then I suspect it would be difficult to distinguish between the two.

Having decided the quality was impressive I decided to see what the range was like. I looked at the box and noticed it said metres, which isn't really that great to be honest but big enough for my house, so I went off to explore. To be fair it does quite well for it's 10 metre range, but remember this is in optimal conditions and so does not take walls, interference and other obstacles into consideration, which is why the signal started to degrade after about 8 metres (estimated).

In terms of comfort, they are fantastic and very nice to wear. Don't think I would have any problems wearing these for hours on end, and the quality and build of the headphones is also impressive....not cheap looking or feeling at all...pretty classy in fact :)

Price wise, they are not exactly cheap, but I guess you get what you pay for. Having said that, I think I would like to see double the range for this price point, which is my only real complaint.

Overall a great product.

Recommended!!!
