Awesome Headset!!

Sound quality is awesome, and my friends highly complimented my voice quality as well. The microphone is a little limp, just don't flip it back and forth a lot. Comes with a little black bag for storage. Lights up mouthpiece when on with a blue light.

The voice quality is amazing on this headset! I use it when working from home via VPN. I use it with my laptop's Cisco IP phone. The cord is very long, which is nice, and the headset is VERY comfortable on the ear. I tried using different headsets that cover both ears, and I hated not hearing my own voice or other things going on around me.
