Bose QuietControl 30 wireless headphones review: A nearly perfect set of active noise-canceling earphones

PCWorld 

Bose first brought its active noise-cancelation technology to its earphones with its QuietComfort 20. Until then, ANC headphones were bulky affairs. The closest you'd get to compact was if they collapsed down small enough to be jammed into your carry-on bag. The earphones, with their inline controls and combination battery pack/ANC hardware, were compact enough to tuck into a hip pocket. Other companies followed Bose's lead, introducing similar hardware of their own.
