Summary: I was looking for a bluetooth solution that would allow me to listen to music and switch over to voice chat. This will do that, however music sounded very tingy and lacked the dynamic sound quality. I returned them.
Pros: Pros are limited to the features of the headset I won't list them here.
Cons: I am mad at myself for not trusting the reviews.. Please look ALL over the interwebz :P you will find people talking about how this headset just "stops charging" I own 3 other Logitech headsets and have NEVER had this issue. I think it ridiculous that they can charge so much for something so cheaply made. I am lucky to have purchased a extended warranty but that said I have only owned it 2 months.
Summary: Pairing is easy. Sound is OK. Build quality is subpar - cheap flimsy plastic, microphone is dead from the box. Remember, when you turn off this headset it will not switch to your laptop audio back. You need to pull the USB plug out.
Summary: Sometimes this headset works fine. Sometimes, the audio crackles horribly and often the microphone input gets so distorted people can't hear what I'm saying. I've tried every software solution, and the problem is clearly the hardware. The battery isn't great so I keep it constantly plugged in, but audio still transmits wirelessly. Will never buy headset from logitech again.
Summary: This logitech wireless headset broke after 3 months of use. Both of the speakers are blown and they now sound really bad. But the time they did work they worked grate the sound was awesome and I was very happy with it.
