Summary: I was hesitant to spring for this headset based on some of the past reviews, but I'm happy I did. I have had one instance of the headset losing its connection and having to pair it again with my iPhone 5 in about 6 weeks of ownership. That's not to say it doesn't drop a second or two of music once in a long while, but every bluetooth headset I've owned does that. Putting the phone on the same side of your body as the receiver goes a long way toward fixing this issue.
Pros: Surprisingly good noise cancellation. Wide dynamic range, great sound. Good performance on voice calls even in noisy environments. Quality construction.
Cons: Inability to check the battery charge level.
