Best answer: I have not yet seen definitive details for the duration of the headset battery while in use. The Sony website simply states "A lightweight, durable design that’s comfortable to wear for hours, with an extended-life battery so you can stay in the game longer between recharges." What that truly means is anyone's guess at this point.
If you have a link to the 15 hour rumor, could you please post. I just bought the TB Stealth 520 that were released on 10/2/16 and it also says 15 hours of battery life (which, in my experience with TB headsets, is usually pretty close to accurate, but I have not had them long enough to test).
Sorry, there was a problem. Please try again later.
