I have similar issues to what everyone else is reporting with regards LED colour of lights, not apparently fully charging etc. However, I also have the problem of the phones not working correctly, in that no sound is being picked up. The only way to again get them to pick up the sound is to force a firmware update of the phones. They then work correctly! This is almost an everyday occurence. Please Corsair, get your act together. I have a keyboard as well, but with these apparent software/firmware bugs I'll think twice about replacements.
