The Monitor III A.N.C. wireless headphones by Marshall deliver an exceptional 70-hour battery life even with Active Noise Cancelling on, making them a standout choice.
I bought this nifty gadget about six months ago for a multi-leg, ultra long-haul trip and it more than held up the entire duration. I was able to finagle it to fit the tray tables on different planes and like others, I find the height just nice when clamped onto a stowed tray table. It also works on my roller carry-on handle during layovers.
