I live for wireless
If you're going for audiophile quality sound, then these probably aren't for you. If you want a convenient wireless headphone system to watch TV or casually listen to music while moving about the house, then these are great. The sound quality is comparable to most inexpensive corded headphones and these sound better than other wireless headphones I've tried. They're light and comfortable and you just stick them back into the base to recharge. Supposedly the batteries last 4 hours per charge, but I've never tested that. The base features a slot to charge an additional battery (that can be purchased ...) and you can swap batteries quite easily.

This model has 3 frequencies that you can choose from by pressing a button on the base. If you have two of these, then you can use them both by leaving the bases on different frequencies. The headsets can then be tuned to either frequency (so both headsets can be tuned to listen to the same base signal). Unlike a cordless phone, where the handset switches frequency channels simultaneouly with the base station, this headset requires you to tune the headset to the frequency of the base station. This isn't hard at all, but this might explain why that other reviewer couldn't get a signal out of this (so read the manual). Along with the tuning dial, the headset also has a volume dial built-in.

Good product spoiled by AGC
I bought these for listening to classical music late at night without disturbing my apartment neighbors. I use a computer to play all my music, and hate being tied to my workstation while listening by a cord, so I was willing to compromise on audio quality for the sake of wireless convenience. In fact I was pleasantly suprised by the sound, which is rich and full, and not at all lacking in bass. Range is adequate for my small apartment, and interference noise has not been any problem for me.
But, there is one problem which makes them almost useless; they have Automatic Gain Control (AGC), which compresses the dynamic range of the output. To explain a little -- popular songs are recorded at a near-constant level, so setting the output amplification automatically to give a constant average signal is not noticeable, but most classical music varies very widely in audio level. A big orchestral climax, with every instrument going full blast, might be followed by a solo flute playing very quietly. Or, a long diminuendo in a piano sonata might fade to a brief silence, and then, for dramatic effect, comes a big fortissimo chord. What happens here is that the volume automatically cranks up during the diminuendo keeping it almost as loud as the loudest of passages, then I hear hiss during the silence, as the gain is too high, and then the loud chord that follows is momentarily deafeningly distorted, and then very quickly the AGC cuts down the volume to be about the same as the overly amplified preceding very quiet passage. This largely ruins the music for me.
If I could only turn the AGC off, these headphones would be fine for me, but it is not even mentioned anywhere in the tech specs nor in the user manual.
I believe in fact all wireless headphones have this feature, although it is seldom mentioned. I now wish I had bought the AKG brand, because I found in their user forums a hack to disable the AGC on the transmitter unit, although this requires soldering on the circuit board. Unfortunately Sennheiser does not seem to have forums, so I guess I'm out of luck with these.

It's time to cut the cord - these are worth the $$$.
I work around ridiculously loud coworkers, so I always listen to headphones at work. Problem was, I hated being tethered to my computer.After reading reviews on amazon.com, bestbuy.com, and circuitcity.com, I decided to try the Sennheisers. They were definitely the best choice of quality and value.

I admit I've only had them for a day, but they sound as good as my wired headphones and were a breeze to begin using. They also help tune out everyone else (bonus!). I don't know what was going on with the few bad reviews I read - operator error maybe? I was listening to music within 2 minutes (literally) of plugging into my PC. The headphones are not heavy and they are nicely padded - really comfy to use.

As of right now, I highly recommend these headphones. The only reason I gave them four stars instead of five is because of my limited time having them and the battery is limited to four hours of continous listening. I'm planning to buy an additional battery pack since it can charge while I'm using the headphones (also available on Amazon) and that way I can listen all 8 hours while at work.

If you're still skeptical, the vendor who sends the product through Amazon has a return policy of 30 days (just double check this) so they're definitely worth trying.

It's time to cut the cord - wireless is the way to go.

Not For Office Use!!
I needed a good set of headphones for some of the work that I do. I thought that by the information presented in the write up about this product that I was purchasing a good, or even great, addition to my office.

NO GOOD! If you have typical office construction, that is metal studs in walls, metal ceiling grids holding up tiles and lights, and other typical office furniture this product will not make you happy!

Disgusting
Horrible headphones. Complete static. No bass. I STRONGLY recommend that you NOT buy these. Battery life very low, complete opposite of sound cancelling, with volume all the way up, you can hear it in the other room. If you are looking for wireless headphones, these are not the answer, a complete waste of $80 ... Read more
