I have these I bought about a 14 months ago @ $99. Worked great but recently the micro USB port has been shorting out and not taking a charge. I have to jimmy the cable until it charges in the "perfect" position. Really annoying if I'm expecting it to charge overnight only to have it die in the middle of a round.
Even when it's working the connection does drop fairly regularly. I sit right next to the USB dongle so it's not a distance thing. Very annoying. Sometimes the audio would drop completely and I'd have to quit the program and restart.
I can't recommend this for the price their charging and issues experienced. It seems like a question of "when" not "if" you'll run into significant issues with this set. Google issues or "g930 broken" and read all of the issues reported.
Dude the device has a 3 year warranty! I would contact Logitech right away. I had a issue with a battery and they replaced my battery no questions asked and even mailed it to me via 2 day express shipping! Logitech's the best company for warranties usually!
