A:AnswerDon’t do this you’ll damage your hearing. Tinnitus really sucks. But no, they will at best hear a very muffled version of what you are listening to. This is the difference between closed backs (these) vs open backs like the Sennheiser HD600.
A:AnswerThey didnt take that long to charge when i got them, and ive used them quite a bit and they say they still have 80% so the battery is really good
A:AnswerYes and then some. You can adjust from 20% to 80% then control the level from a dial on the left side. You feel it like you feel the vibrations on your phone. Old school bass hitting your ears. You won't be disappointed. I really enjoy mine.
A:AnswerYes, they block a lot when listening to musci, it has three different modes, the canceling, to hear more outside the headpgones, and to disbale all modes to feel like if they were off.
