Not very good
Nice idea, and they look good
Very poor sound quality and reception
I wanted to pipe sound from my stereo to my bathroom. However, I never got past the set up phase which involves tuning the speakers very close to the transmitter. Even from 10 feet away, the reception was not very clear, and the sound quality was terrible. Carrying a speaker into the bathroom 75 feet and two drywall layers away completely lost the signal. Wireless speakers are a great concept, but these are not good for music. Maybe if you just wanted to listen to talk radio or sports they would be OK.
