1. Make sure your earbuds have enough power before resetting them:
*Place the earbuds into the charging case and keep the case open.
*Press and hold the button on the charging case for 10 seconds until 3 LED indicators on the charging case flash white 3 times and then flash white in sequence continuously. This confirms that the reset was successful.
2. Clear all the pairing records on your Windows computer and re-pair your earbuds. Make sure you choose the right mode (For audio/video, choose Stereo, and for mic choose Hands-Free)
3. Turn up the volume of your computer, earbuds and music/video to the maximum.
4. Use a Q-tip with a bit of rubbing alcohol to gently clean the metal mesh filter under the rubber ear tips.
