This is your instruction manual, to help create the best possible experience with this cool product. Earbuds Power Case Type-C Charging Cable The battery isolators, on the bottom of the earbud stem, need to be removed in order to charge the earbuds. Place the earbuds securely into the power case. Earbuds will begin charging automatically. The charging case LED(4) will turn solid BLUE and earbud LED(2) will turn solid RED when charging. The LED on the earbuds and case will turn of f when the earbuds are fully charged. Use the provided USB to Type-C charging cable to connect to an adapter or computer to charge the power case. When charging the case the LED(4) will case is fully charged. It takes approximately 2.5hrs to charge the case from 0%-100%. When the case is fully charged it will charge the earbuds 4-5 times from 0%-100%. Remove both earbuds from the power case, you’ll hear a voice prompt on both earbuds saying “Power On” followed by the tone prompt indicating earbuds are paired. Once you hear both earbuds beep the earbuds are now synced to each other. If done successfully the main earbud LED will turn off and secondary earbud LED flash slowly. Go into your Bluetooth options and select the pairing name “Looking Glass TWS”. If done successfully you will hear the voice prompt “Connected”. You can now enjoy your favorite Audio. Previously connected earbuds will connect automatically after they’re powered ON. If you don’t connect to the earbuds within 3 minutes the earbuds will automatically power OFF. Remove your earbuds from the charging case or press and hold the multi-function sensor(1) for 3 seconds. You’ll hear the voice prompt “Power On”. holding the multi-function sensor on both earbuds until you hear the voice prompt “Power Off”. Right Earbud: - Double Press to play next song - Triple Press to increase volume Left Earbud: - Double press to play previous song. - Triple Press to decrease volume. If you’re having trouble pairing your earbuds forget the pairing name “Looking Glass TWS” from the list of connected devices. Now turn off your Bluetooth. Place both earbuds back into the charged power case. Now remove the earbuds and follow the instructions under “Pairing Both Earbuds”. Answering/End Call: Press the multifunction sensor once to answer an incoming call, and again to end the call. Reject a Call: Press and hold the multifunction sensor to reject an incoming call.
