1) Before pairing, make sure the earbuds and the mobile / laptop are next to each other.

2) Put both buds in the case and open the lid – the buds enter pairing mode as soon as the lid is opened. To force pairing, long-press the case button 10 seconds until the white LED flashes thrice.

3) If the phone's Bluetooth list doesn't show 'ALT BUDS / ALT BUDS(S)', 'Forget' any old entry and restart the phone's Bluetooth (toggle OFF then ON).

4) Toggle Airplane mode ON then OFF on the phone.

5) Restart the mobile phone.

6) Ensure the buds are NOT already connected to another phone / laptop / tablet in range – switch Bluetooth off on those devices and retry.

7) Charge the buds in the case for 30 minutes to verify charging (case Dot LED: orange while charging, white when full).

8) If there is NO LED, NO voice prompt and NO charging indication, treat it as a dead-device case.

Note: The MAIN earbud enters pairing mode automatically only when it has no pairing record or right after a Reset. If a record already exists, opening the lid makes the buds RE-CONNECT instead of pairing. Most 'unable to pair' cases are the buds already connected to another device, or not actually in pairing mode; if the device isn't dead, the issue is usually on the mobile side.
