A full week of long sessions on a single charge. 7.1 virtual surround places footsteps and reloads, and 15ms latency keeps audio in step with the picture. The noise cancelling boom mic flips up out of the way when you are not talking, and the frame is light enough to forget you have it on.
Surround is virtual, so it is stereo imaging rather than true positional drivers. Works well for shooters anyway.
