So I play in pit orchestras a lot and, recently, we are being run through the house system and we get to keep out amps as monitors just so we can hear ourselves. Well I don't know if it's because of the difference in location or because the keyboard's monitor is so dang loud, but I can't hear myself whatsoever. I need some headphones that are cheap, good for bass, able to function with one ear, and preferably wireless.
