Pros: Good microphone, they can hear me well. Great battery life. MicroUSB connector for charging, no custom or patented connectors like Plantronics. Battery level and call number announcements in English.

So-so: Average range. The "headband," although adjustable, is limited to medium-small sized heads.

Cons: Terrible sound quality, no treble or bass, sounds like it's coming from a thick sponge with muffled sound. I struggle to understand what my caller is saying. The ear cushion is low quality and expected to deteriorate in a few weeks. The main button (on/off/pair/answer/hang up) is hard and pressing it is very audible in the ear. The same goes for the volume buttons. There is no voice recognition for hands-free call acceptance/rejection.
