Review on Edifier W820NB Headphones - Hybrid ANC - Hi-Res Audio - 49H Battery Life - Bluetooth Over Ear Wireless Headphones for Phone Calls - Black by Alvin Yongwei ᠌

Well-functioning active noise cancellation (now in this price category) - homogeneous noise generally cuts off with a bang, the noisy kettle seems to turn off when the headphones are turned on. They sit comfortably on the ears - I fell asleep in them several times and no inconvenience. A good circuit with a USB-C connection - you can connect a wire to modern smartphones or to a computer (it is defined as an external audio card without installing drivers, the wire is included, it is just in the photo). At the same time, the headphones are charging at the same time, which in the case of a smartphone can be a minus (there is a 400 mAh battery, taking into account losses, the smartphone will give all 500, and quite quickly), because you can’t turn it off. But with a computer it's definitely a plus - I switched it to a wire and at the same time replenished the charge.
