Summary: I reviewed this prior to purchase and the major drawback appeared to be that they speakers hissed when no sound was played out from them - but were still on. I can confirm that they do do this - ever so slightly. And yes, clearly an oversight on some techie's part. But, this is such a small issue. Either never turn of the music - or turn them off! Simple fix. The sound is great, the bass long and deep. I approve!
