A:AnswerYou need to turn down the tv volume because it will
Still go through both if you use the tv sound bar. Chat will go through the headphones. The 600s I think are better.
A:AnswerIt can last quite a bit actually I’ve used it for hours straight on max volume maybe 3 hours of nonstop gaming? I haven’t actually measured but it’s long enough for long game sessions. You can charge while using but make sure you have a long enough cable otherwise it will be wrapped around you..
A:AnswerI made the jump. They are definitely worth $50 additional bucks. I believe the sound is slightly better with the 420x, but there are a few enhancements. The soft cushion around the earphones is a better feel and there is no longer a USB adapter to connect. These headphones connect directly to the console. The retractable folding mic is convenient when wanting to mute any chat rooms. Overall its a good buy for true wireless headphones under $100.
