Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
cracks and pops
As many people have pointed out, be prepared for static and temporary loss of signal as you move around while wearing these. It might annoy you (like me) to the point of having to go through the hassle of returning them. I do find them light and comfy, and the sound is fine ifmost of the time. If you keep your head stationary you won't have any break in the sound. But if your head is perfectly stationary, do you really need cordless? My opinion: live with the cord if you can...until the technology gets a bit better... it will.
