Summary: Very easy to use and set up. I use it as a headset for tech support calls from home. The audio in and out is sufficient for my purpose. However, after wearing the headset for longer than a couple of minutes my head starts to hurt; not good when you are on tech support all day.
Pros: Comfortable on the ears, good sound in terms of people talking. Easy to set up.
Cons: Very uncomfortable on top of the head; there is no 'comfort' piece on the head. In fact, there are just two plastic sharp rails that rests on top of your head - ouch. The unit is quite heavy which makes the situation with the head piece worse.
Summary: This headset is excellent on the price and the sound quality. You can hear clearly, not a muffled sound in your ears. It is great for PC chatting. I have ONE MAJOR COMPLAINT...no mute button. If you have to cough, sneeze, or talk to someone in your home/space they will hear it all.
Excerpt: I purchased this headset to make Skype calls with my Surface Pro3. This headset is very comfortable when worn for long periods of time. The sound is clear and external noises are mitigated. The microphone is not obtrusive and very effective.
