5 out of 5 stars Great for TV watching; wish I'd ordered them sooner   April 7, 2006
Aaron Contorer (San Diego, USA)
71 out of 72 found this review helpful

These headphones are clearly not intended for listening to music at high quality. But I have been using them to listen to my TV, and am delighted with the ease of setup, ease of use, long battery life, and apparent immunity from interference. br / br /You can't use them outside the room, and the sound quality is good but not great. Perfect for TV. Even if obstacles partly block the infrared path, the sound continues uninterrupted. The headphones are comfortable and light, and run for many hours before recharging. br / br /I am totally satisfied with the product, and only wish I had ordered something like this years ago!


5 out of 5 stars Great Headset   April 4, 2006

They do a great job. I got them to watch TV at night without disturbing others. The sound is great, no distortion by turning up the TV volume and lowering the one in the headset. Charge last a long time, charged them once over a week ago and still sounding great. I like that I can use any AAA battery when it runs down on charge, so I don't need for it to charge to use it, but if I place it in the charger/base once a week it keeps the charge, no problem with that at all. br /On and off button on headset is a big plus, no need to get up to place on base after each use. br /The sound quality is great and clear, even when watching TV and using my Wireless laptop, they don't interfere with each other. They are comfortable, not tight so that could be a problem for some people but I like them like that. If you want to walk around the house or go out in the yard while listening to music, these are not for you, these are for getting clear, great sound in the same room without interference. Once you walk out the door and have a wall in between you and the base you will loose the sound. br /Get these if you just want to watch TV or listen to music while in the same room as your equipment. I loose the signal at 20 feet away.


5 out of 5 stars Lightweight, Comfortable, Functional, and Cute   February 15, 2004

I use them in a bedroom for TV, stereo, and PC; range has not been an issue at all. If you chiefly want range, buy RF (radio frequency) 'phones. I've owned these for a good three months with no more than the initial charge (using them an avg of 2hrs/wk)! I just lay them over the stand instead of in the upright charge position. br / br /Sound quality is good; I notice no degradation, only the change in audio channel type. They are comfortable. I don't see a drawback to the top part resting on your head like normal 'phones do. The earpads are like a Walkman's, not the "plushy" kind that make your ears warm in a short time. Small and lightweight like Walkman 'phones, this item passes every test of functionality and looks good doing it! br / br /...After 2 years of flawless performance, I must downgrade my rating to 4 STARS based on my experience. This is due to the lack of versatility of the headphones. Whether I have the volume cranked on the source (like you're supposed to) or lower it, I am suddenly getting a very disturbing hissing sound together with an excessively loud signal, even with the volume on the headphones at zero! This is happening whether I use my PC, stereo, or DVD player as the source. I'm guessing it has to do with my plugging it into a Belkin surge protector and using a Radio Shack adapter that somehow zapped the base. When I did that on one occasion, I suddenly got no signal to pass through even when I switched back to the Sony adapter. But then it came back to life when I plugged it into the wall outlet, only now it was permanently damaged. I recommend you learn from my mistake and buy a second unit for $40-$50 if you like the first and need another one for another sound source(s) and don't plug it into a Belkin surge protector (APC is fine). I just bought myself a new pair. If I notice any problems, I will post a new review.


5 out of 5 stars A great buy!   February 21, 2005

I've had these headphones for about a month now, and they have performed excellently throughout. br / br /My previous set of wireless headphones required constant tuning and often lost the signal of the base station. These headphones, conversely, have a large range of reception and generate little static throughout that area. Charging is simple--simply place the headphones on the base station to recharge. While the included rechargeable battery supposedly has a 15-hour limit, I've yet to lose power--although I've never really put them to the test, as recharging is so simple that it becomes reflexive. br /The battery can also be replaced by 60-hour AAA Bateries (not included). br / br /Sound quality is good--not as crisp as some high-end pairs of headphones, but about as good as a pair of around-ear headphones and certainly as good as traditional PC speakers. While there is a faint hissing noise produced by the headsets, I didn't find it annoying or hindering in gaming, listening to music, or watching movies. br / br /Bass is decent. br / br /My only issue with the headphones is that they don't turn on instantly when returning from "standby" mode, which they enter after a few minutes without use. The delay is only a second or two, however, and not a major concern. br / br /Otherwise, I wholeheartedly encourage the selection of these headphones.


5 out of 5 stars Ideal for students   November 28, 2004
Happy user
13 out of 13 found this review helpful

I received these around June 15, 2004, and on November 28, 2004, the battery finally ran out. I use these every day and every night to go to sleep by, and am not even always conscientious about turning them off or putting them in the charger, so I have found the lifespan of the included battery to be wonderful. If you live in any kind of shared room, as in a dorm or barracks, these are perfect. Mine are hooked up to my computer and I can watch movies, listen to music, and hear anything on the internet without my roommate having to hear what I'm listening to. Sound quality is perfectly acceptable for most normal people, and the limited range isn't an issue in a dormroom setting. I love these. br /(Update 22 March 2005-- I'm still using the original batteries. I have to make sure to put the 'phones in the charger more often, and have noticed a little deterioration in range and quality, but I'm sure these issues would be easily corrected by putting in fresh batteries. I go to sleep with them on my head every night and I wear them almost continuously when I'm at home. As I said before, ideal for students, long life, reliable, and a great buy.)
