2BCJE-MDWireless Headphones

Wireless Headphones Instruction Manuall Please read the manual carefully and keep it for reference CONFIGURATION PARAMETER Pairing Name: MD Chip version: 5.3 Charging time: About 1-2h PRODUCT INTRODUCTION 1.Charging box*1 2.Left and right headphones*1 3.data line*1 4.Product specification*1 BINAURAL PAIRING CONNECTION 1. Picking up the earphones will automatically turn on and pair, and the pairing is successful. The main earphone light will flash alternately, and the secondary earphone LED light will turn off (if there is no pairing, simply double-click any earphone to pair). 2. Open the wireless list of the device and search for "MD"; 3. Click to complete the connection (LED light off). If the connection fails, put the headphones back into the charging case, close the cover, and repeat the above operation. If both ears leave the device at the same time beyond the distance, the headphones will enter a reconnection state. If there is no reconnection to the device within 3 minutes, both headphones will automatically shut down. After the first connection, the earphones will automatically reconnect to the last paired device after restarting (provided that the phone's Bluetooth is turned on) Switch between English and Chinese Headset boot without connecting any device in the case of Boot, press 5 buttons (quick press) can be switched between English and Chinese freely. OPERATION MODE Operating instructions (1) Pick up the earphones and immediately turn them on automatically, with the light on for 1 second. (2) When the headphones are turned off, press and hold the function button for 1 second, and the voice prompt "power on" light will light up for 1 second. 1.POWER ON 2.SHUT DOWN (1) Put the earphones back into the charging case and close the cover. The earphones will automatically turn off and the light will be on for 1 second when charging. (2) When the headphones are turned on, press and hold the function button for 3 seconds to turn off the headphones, and the voice prompt "turn off" light will light up for 1 second.
