M22 TWS Wireless Bluetooth Earphones Couple Earbuds In-ear Headphones HiFi Stereo Sports Waterproof Headsets For All Smartphones

Notes:

If the headset you received has only one earbud to use for the first time, then you can do as I said, delete the bluetooth name in the phone, take all the earbuds out of the charging box, and then pair it again

The earbuds of this product are protected by transparent tape at the charging place of the charging compartment, please tear off the transparent tape as soon as possible after receiving the product and pair

Note:

M22 can be used with one ear and two ears, not all earbuds on a single device.
