I bought these as a temporary measure when my earphones broke, so I haven't used them much. Includes the manual. Alcohol-sterilized. I've confirmed they work without any problems. The third photo was taken through my PC screen, so it's a bit rough, but it shows the connection confirmation screen. - Model Name: T09 - Charging Case Display: Digital display - LED Indicator: Red LED - Connection Status: Connected via Bluetooth - Battery Level: 100% Thank you for looking.
