I have used these headphones for about 5 months and pretty much hate them, here's why.* the stand allows you to select 3 different discrete frequencies, but the headphones make you tune it in to the right frequency with an analog knob, which is awkward, imprecise and is always getting knocked when I adjust volume. If there's 3 possible frequency settings on the base, there should be 3 on the headphones.* after a minute of no output from your computer the headphones will generate static VERY loudly into your ears. Apparently this is to save "battery" life, I'm not sure how generating very loud static saves any battery life, and since all you need to do on your PC to start them up again is press play, so clearly it hasn't turned off the receiver. If it went dead silent that would be fine, but generating static is annoying/pointless.I'm not an audiophile, I don't care about the sound quality so much, I just want an easy to use pair of wireless headphones, this is not it.
