The WH850i is an over-ear Bluetooth headphone with active noise cancellation. The noise reduction depth is 25dB. It uses Bluetooth 5.3 and works within about 10 meters.
It has 40mm dynamic drivers with a PET diaphragm. A game mode lowers audio delay for gaming. When the battery is empty or you prefer a cable, the included AUX connection plugs into a computer or any 3.5mm audio port.
The headband is lightweight and ergonomic. The ear cushions are protein leather over zero-pressure memory foam, which is soft and breathable.
