There is an opinion that it is necessary to take headphones of the same company as the phone. Therefore, I took these ears to my note 8. After changing the phone to note 20, the sound became noticeably better and the connection was easier. Even with Bluetooth turned off, when you open the case, the smartphone detects the headphones and asks if you need to establish a connection. They hold the battery for a long time, I didn’t measure it directly, but my wife’s airpods are dying, and I have more than half.
