Paired it with SonyE. W710 with no problem. Sound quality is pretty good. Not as good as the wired headset but good enough. Battery is good, at least 5 hours. The earbuds would fall if you don't wear them over the ear. The biggest problem is that if my phone is not in my shirt pocket at least 3 inches from the pendant, like say in my pants pocket, it will be nearly impossible to listen to the streamed music. It keeps losing the signal if there's anything in between the phone and the headset pendant. I'm not sure if it's my phone or the headset but I have a S.E. W710 walkman phone. You think they would work well together.
