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

Neodymium magnets give you a high fidelity, FM stereo sound reproduction.

Volume control on ear piece, auto power On/Off

Battery

A good investment for the money. I had my set for a year or more and have had no problems with static or lost signal even from 15 to 25 ft away. September 27, 2012
Nothing but Static Permanent static regardless of what I do. I can hear sound but the static is still there. Even if the audio jack is not connected, the static is still there. Seems like it's an issue with the base. July 5, 2012
design flaw These headphones would be great if we didn't have to cram stuff between them to keep them connected to the charging base and this doesn't always work! Its frustrating that we spent over 200 dollars on two sets of earphones that half the time don't work!! :( May 19, 2012
static poor reception for $130Cdn, its not a great buy. At 8 ft away sitting on the couch, if you move your head side to side the static almost makes you take off the headset. with today's technology, these should be sold at the dollar store so you wont be disappointed when you put them on.
