Headset Connection Guide: 1. Open the charging case and take out both earphones at the same time. Wait for 3–5 seconds. 2. Turn on Bluetooth on your smart device (phone, computer, tablet) and search for the model "A7". 3. Select the corresponding model to connect for the first time and click "Pair." (When using again, the earphones will automatically reconnect to your phone's Bluetooth if not paired with another device.) Possible Problems and Solutions During Use: When the headset cannot connect to the device: ① Check the Bluetooth settings. Make sure the headset is powered on and the device's Bluetooth is enabled. Confirm the correct model is selected. ② If the headset is not connected for a long time (about 5 minutes), it may shut down automatically. Try placing the earphones back in the case, close the lid, then reopen and reconnect. When one earbud cannot connect: ① Long press the earbud with no sound until you hear a "du" sound - this indicates a successful connection. ② Put both earbuds back into the charging case, turn off your device's Bluetooth, then try reconnecting. ③ Delete the paired device record from your Bluetooth list, then reconnect the earphones as a new device. Sound leakage from the headset: ① Wear the earbuds tightly in your ears to ensure a proper fit. ② If the volume is too high, try turning it down. Short battery life: The headset battery may be low. Place the earbuds back into the charging case with sufficient power. Charge until the case indicator light turns off - this means the earbuds are fully charged.
