What is Radio Frequency?

Radio Frequency transmission works by sending our radio frequency signals from the transmitter to the headphones. Radio frequency signals allow high fidelity sound reproduction and have a large reception range that does not require keeping the headphones within line of sight of the transmission. Radio frequency signal quality can deteriorate due to external noise and interference in some settings.

Sound

Noise reduction technology reduces interference and neodymium magnets give you a high fidelity sound reproduction.

Transmission

900MHz radio frequency transmission with up to 150 ft transmission range.

Additional Features

Volume control on ear piece, auto power On/Off

Design

Comfortable fit with adjustable headband and complete coverage of the ear.

Battery

Supplied rechargeable nickel-metal hydride battery automatically charge by placing the headphones on the transmitter base station; headphones charge via electromagnetic induction charging.

Comfort and quality These headphones provide a high quality sound and the large size provides the comfort needed to wear for several hours. They are not heavy and I don't even realize that I'm wearing them after a short while. I highly recommend these for anyone who likes to watch TV in bed and not disturb anyone. December 28, 2008
Great Wireless Headphones Under $100 I bought these headphones earlier this week from Best Buy. Like those reading this review I researched and read other reviews and saw the same 1 star reviews many had written about this product. However, I decided to get these anyway hoping to have better luck....I am so happy I did! These headphones work great and look great too! I love that they are wireless (main reason I bought them) and I am having no problems at all. I have a sony home theater system and everything (plasma hdtv, cable box, PS3) has sound going into that. I also have a D-link wireless router about 1 ft. away from the headphone's transmitter too. I followed the advice I read elsewhere about turning up the volume on the source higher (in my case, my sony surround sound system) and keeping the volume selector on the headphones lower instead of maxed out and it works like a charm...perhaps others aren't doing this? Sometimes when i turn them on I get a little static but thats why the tuning button is there...one press of the button and it's gone. I dont know what the deal is with the negative reviews but I am very happy with my purchase. Now I can watch movies or play COD Black Ops without disturbing anyone and listen as loud as I want WIRELESSLY! July 1, 2012
Garbage These headphones never did work and I got them as a gift from my wife. she threw away the receipt so now I am stuck with an overpriced paperweight. these headphones are fit to be thrown in the trash can only. uncomfortable to wear But I have never had them on more than 5 mins anyways... since i can't get them to work on ANY device I have in our house. Defective and non returnable. Total junk. June 11, 2012
Too Much Static I decided to buy these since it was a little cheaper than going with the Bluetooth headset. Well as they say you get what you pay for. in this case not much. The build quality is good but the sound is terrible. I'm only 6 feet from the TV and the charging base and I hear static. It will get louder or softer when I turn my head. It doesn't matter where I'm sitting or moving in the living room you still get the static. Very disappointed. It doesn't matter if I have the volume low or high on the headphones. The higher the volume on the headphones the more you hear the static. Save yourself the disappointment and go with a Bluetooth headset. May 22, 2012
