Boy was I excited to get the new wireless speakers. Sounded great, solved the problem of using the computer to be the"radio". ...for about 4 hours then a little speaker rattle. No problem...just lower the volume... for about 1 hour..then nothing. Argh!I have to say in the defense of the speakers that while they worked the sound was fine for my ears.Maybe this was a fluke, or maybe the issue is systemic. I dunno, I'm waiting for replacements to find out.
