Bests & Worsts Reviews from Amazon

The device itself, as headphones works great. The build quality is nice with a soft rubber finish. Being able to wireless-charge the buds with the case is a convenient feature. These fit me well and remain in place. These are also good at isolating you from outside noise. A major annoyance: I don't think you can use these in mono mode. The right bud will beep every 10 seconds or so if used alone. I think if you pull out the left bud, let it connect and replace it back in the case, the right bud will beep for 20 seconds (once per 10s interval) and then it seems to stop. An annoyance, but still a 5-star product at this point. The reason for the 1 star review: the microphone is completely useless. It's not even sub-par or low quality. I call my work line using my cell and even with the right bud 2 inches from my mouth, my own voice felt like very low background noise -from far, far away. I really wanted to like these... but I'll have to return them.
