I have had them for several months now. When they remember to play, they play perfectly, but very often they do not connect to the Xbox. It throws a message that they are connected and disconnects them immediately, and it keeps doing the same thing continuously. I tried to pair them again with the Xbox, but to no avail; it disconnects them constantly, whether I restart or update, they simply do not connect. I have done a firmware update, but still nothing. It has now been 3 weeks since they connected only one day (presumably they forgot and decided to work). If I am doing something wrong, someone please let me know because I have been very frustrated with these. Oh, and Razer does not take them for repair - inspection because I bought them from Skroutz, and this store brings Razer products from parallel imports and not from Razer. Nice!
