The adapter worked as advertised and was well built for the most part. You can connect a PC headset with mic to your xbox 360 controller as expected. There are 2 main downsides though (albeit one is really a minor and subjective issue):
(1) (and this is the minor one) The audio inputs aim downward, so depending on your headset, your audio jacks may protrude downward and make it awkward to play with. Granted this is highly dependent on whether or not you have straight or 90degree bent jacks, and whether or not you sit back and play with the controller close to your lap or not. Again, very subjective issue.
(2) (This is the biggie) Voice audio must be set to output thru your TV/Receiver rather than back directly thru your headset. The downside of this is that if there are no separate in-game volume adjustments of sound effects / voice / music, then voice audio from your online friends is drowned out quickly. In several games, such as GRAW2, I couldn't hear anything anyone said in the menus, and during the game, I could barely make out what anyone said unless i stopped moving around and no one was shooting.
So unfortunately, if you are going to use this online to play on live and talk to other people, then you probably want to check elsewhere unless the games you are playing specifically have separate in-game volume adjustments for the 3 types of audio.
