The first thing I want to say and rate the highest is how comfortable they are. I have literally worn these for hours! I've tried them out in many different ways - connected to my phone, connected to my computer and used while gaming, connected to listen to music while I'm driving, etc. I like them very much and will continue to use them. Are they perfect? No. The biggest negative is that there were times that even at full volume on the headset and device, it wasn't enough to combat the other noise around me. The worst was when I was driving with the windows down. (That had been my biggest hope.) In spite of that, even at its worst, they were still better than not having them. I really like how easy they were to wear and to forget that I was wearing them.Sound quality: Good sound for music, though the bass wasn't as good as I would have liked. The higher the base in the music, the more it would tickle my ears, which amused me. Sound quality wasn't as good for phone calls. I could be heard and understood but for both parties, the sound seemed a little muffled, as if the other person were on the other side of a door.Honestly, I'm really pleased with these, taking everything into consideration. It was the first time I'd ever used a bone conduction headset. Also, a little bonus for me (even if its just vanity...) is that I can wear these fresh out of the shower without it causing my hair to dry in funny positions.
