I've had my RF-MAB2 stereo headset for a few months now, and think it's a great product!
If I could suggest a slight improvement, though, I would ask for some means of completely turning of all lights. I expect there are others in the same situation as me: I like to use them at night, in bed, to listen to some music while I drift off to sleep. However, the blinking blue light is an annoyance, particularly for my wife! It would really be great if, once I'm connected and "up and running", I could stop all light emission from this device. Perhaps a small on/off switch or button could be incorporated in a future version.
