Quality isn't bad these days, with Bluetooth 4.1 having a decent amount of bandwidth for shoving data around, but 50ms+ of latency is going to mess things up for you, even if the average bluetooth user doesn't mind.

VHF wireless systems, like the ones used for guitars, mics, and in-ear monitors, are where I'd start looking. Not gonna be cheap, though.
