Hybrid ANC 60H Playback Foldable Bluetooth Headset with Mic

"Over-ear headphones earn their size in two ways: bigger drivers and room for real noise cancellation. This pair uses both. The hybrid ANC system runs microphones on the outside and the inside of each cup. The outer mics read approaching noise, the inner mics check what actually reached your ear, and the result is up to 32dB of cancellation against the steady low-frequency sound that wears you down - aircraft cabins, bus engines, air-conditioning, office HVAC. When you need to hear the world again, Transparency mode pipes it straight through, so you can catch a boarding announcement or answer a question without pulling a cup off your ear. Battery life is the other advantage of the form factor. There is room for a 500 mAh cell here, which translates to roughly 60 hours of playback with ANC off and around 40 with it on. For most people that is a full fortnight of commuting between charges, and a 10-minute Type-C top-up adds about 10 hours if you forget. Sound comes from 40mm neodymium dynamic drivers - four times the diaphragm area of a typical earbud. The extra area produces low end with weight and control rather than boom, while leaving the midrange clear enough for dialogue in films and for hours of conference calls. Comfort was designed for long sessions: protein-leather memory-foam cushions that seal without squeezing, a padded headband with a wide adjustment range, and a total weight of about 240 g. The cups swivel flat and the frame folds in, so they pack into the supplied pouch rather than taking up a bag. Bluetooth 5.3 supports multipoint, so the headphones stay connected to your laptop and your phone simultaneously and switch to whichever one is playing. And when the battery does die, the included 3.5mm cable turns them into ordinary wired headphones."
