I give this headset an extra star for being fairly comfortable to wear. The volume is good too...if it's working.Like some other reviewers have mentioned, this headset's mic is prone to dying out of the blue, which is exactly what happened to mine. So you're having your usual conversation, and all of a sudden the other person can no longer hear you.I will be buying a replacement headset for my Plantronics phone, but definitely not another of this model. If you do buy this, it might be a good idea to have a replacement ready because it's a huge hassle to have to run off to Radio Shack when your headset dies in the middle of a business call!
