Review on AKG N700NC M2 Wireless Headphones, Active Noise Cancelling - Black (US Version), 2.6, Model: GP-N700HAHCIWA by Samsung by Francis Heart

Used it like new for $90 and I love it! They are more compact than expected but still fit comfortably. The sound quality is incredible, especially with lossless audio. As with all headphones, the bass isn't perfect, but there's so much you can do to mimic a decent subwoofer with a driver of this size, and AKG has done a phenomenal job. There are no dedicated play/pause or skip buttons, but the volume buttons are conveniently located. Active noise cancellation (ANC) is great! It works very well, but when you press the button to switch to pass-through mode, it lowers your music volume to an almost imperceptible level. I wish there was a third option that would overlay two audio sources to emulate open-back headphones, but alas. Battery life could be better, but I get 5-7 hours on a single charge, which is pretty good. Overall they are fantastic and do exactly what they are supposed to do and nothing else. Edit: I was wrong; There is a play/pause button between the volume buttons.
