The Yesido YSP28 is an open-ear Bluetooth earphone with an ear-hook design. It uses ENC noise reduction to filter ambient noise during calls. The open acoustic design lets you hear your surroundings while listening to music.
Each earphone has a 12mm titanium diaphragm speaker. Flexible ear hooks conform to the shape of the ear to hold the earphones in place, including during exercise. It connects over Bluetooth 5.4, and narrow-band directional sound transmission helps keep calls private.
