I ordered two of them to hook up to two amps. a high end pioneer and an older onkyo.At first I didn't really notice the sound was bad as I was playing dub step and other electronic music... but when alanis morisette came on I noticed something... it sounds like a bathroom or hall effect has been added to the music. Most will probably not notice this unless you have good speakers..but I could hear it...I then tried it on my pioneer sc09 and high end speakers and it was really bad. Since I had two units I tried swapping them out but both exhibited same poor sound quality. Well the quality wasn't all bad...just that annoying bathroom echo effect ...also this device does not auto connect when your within range but rather requires you to go into Bluetooth settings and pair every time you want to use itRange was not bad about 20-30 feet throug a couple of interior walls much better than expected 

Question: How is the quality?
Answer: the quality was n't all bad just that annoying bathroom echo effect
