Cons:continuous background noise, and signal loss when moving around, even close to base.
Constant background hiss, even if the volume of the
input is cranked as high as you can get it without
distortion (i.e. at what should be the best signal-to-noise ratio). Even standing 3 feet away from the base, turning my head back and forth slightly loses the signal at several points when the radio signal is at a null--- I'd rather pay twice as much to get something that WORKS PROPERLY. I have a wireless system that lets me plug my electric guitar into my mixing board, and it is rock-solid quiet at any angle of
turning back and forth, at 100 feet. I guess I'll have to find out if there are any diversity-style wireless headphones available.... I suspect that there are-->at more than twice the price! (which I would gladly pay to have a product that's ACCEPTABLE).
