"Impressive functions"4.5 starson by TheeBadOne
Pros: Small, light, great sound
Cons: Need to tweak fit so "tube" is touching cheek.
Summary: I think some of the low reviewers just don't know what they're doing with this headset. Noise Assassin is on by default, and you must wear it so the clear tube is touching your cheek. If you don't, the quality of the call will be terrible on the other end (they will have a hard time hearing you). When I used the attached ear piece I had a hard time keeping the tube in contact with my jaw. I switched ear buds, but nothing seemed to work, it kept losing contact with my cheek. Then I tried switching ear loops, and BINGO, it worked like a charm, tube in constant contact with my cheek and no problems. This thing is worth the attention, and $$$ it commands.
