I've bought one of these before and actually paid a bit more for it, it might have been a different brand but it looks the same to me. The volume buttons didn't work on the first one, but it didn't matter because I didn't have that feature and still don't need it. I use the computer volume control. I only bought it because I couldn't get any sound through the audio jack after a complete reinstall of op. System. You know. One of those lost phantom drivers that wasn't even gone, anything, anything, whatever, I give up? Anyway, everything is fine via the USB port, so I bought an adapter and the headache is solved. Well, I ran into a similar situation when installing computer hardware in a different case. The audio jacks don't work when installed in a new case (must have something to do with the old case having front audio jacks). Once the problem was solved, this time simply by ordering this product for a few dollars. Oh, the volume and mute buttons work well too, but again, it doesn't really matter since you don't need them in this type of app anyway. I wouldn't expect "hard" reliability for $2, but if you plug it in and leave it alone, then this is real value! I'll order another one just for the extra charge.
