Koss CS95 Communication Headset with Noise Cancellation Mic (3.5 mm Jack) for Mic iMac/Laptop/PC/DJ/MP3 Players - Gold | Black

PLEASE can a Mac user answer if the CS95 USB is compatible with OS X? Even the Amazon customer service people could not answer this question!

Can you flip the mic around to put the earpiece on the right ear?

Can the mic rotate 180 either side so it can be worn on the head on both left and right side, depending on a persons preference ?

Does it have volume control or a mute for the microphone?
