A:AnswerThe Astro A40's do leak some sound when off the head, but it is minimal when wearing. Not zero, but I play with no TV volume and no one can hear me playing.
A:AnswerToggle your internal mute in your TV to "on" to cut the TV volume. If you want to hear only tv volume and chat on your headset, open your chat mixer on your xbox and turn game volume to zero.
A:AnswerIf youre talking about recently product the answer is no, the A40's have been around for a while. If you can get your hands on an open box headset i would totally recommend them.
