JBL Live Free NC+ TWS

It is not uncommon to have charging problems with True Wireless headphones. You may encounter that charging stops, does not start at all or that one of the ear buds suddenly switches on and begins the pairing process. This is almost always caused by dirt on the metal charging contacts. These contacts are vulnerable because they can easily be contaminated by sweat, skin grease, or ear wax. They are usually gold plated, but gold plating does not prevent surface dirt.

If you have charging problems, the first step is to always clean all contact points, on each earbud and on the charging case.
You will need: cotton cloth or makeup swab, cotton swabs and rubbing alcohol. Also a pencil with eraser for further cleaning.

Use a cotton swab with some rubbing alcohol to clean the charging terminals of the headphones. Rotate the swab and scrub lightly on each contact surface, then use a cotton cloth to remove any dust and cotton residue left on the headphones. It is important to perform this process periodically to keep your headphones clean, thus avoiding affecting the charging speed/quality.

Wipe the contact pins in the charging case with a clean cotton swab. The swab can be slightly moistened with rubbing alcohol, but it is important that the interior is completely dry before closing the box. Use the cotton cloth and wait for it to dry.

Repeat until the contact points are visibly clean, and charging should work as designed.

Try cleaning the contacts with the tip of a pencil and the eraser at the end of the pencil, the graphite and rubber can help to re-establish charging also.
This procedure can be performed on all TWS earphones and cases.

If you are experiencing issues getting the app to communicate with your headphones, (assuming you have already paired the headphones with the device) go into the communication apps audio settings. You will likely find the resolution there. You may have to set your headphones as the ‘communication device’ within the app you are using.

대부분의 경우 컴퓨터/PC/노트북이 블루투스 기기(휴대용 스피커, 헤드폰, 액티브 스피커)에 연결되면서 문제가 발생하며, 이는 컴퓨터/PC/노트북의 블루투스 드라이버(소프트웨어)가 원인입니다.

드라이버(소프트웨어)가 다음과 같은 블루투스 프로토콜을 지원해야, 컴퓨터/PC/노트북에서 음악/소리를 재생할 수 있습니다.

• A2DP(고급 오디오 배포 프로필) 드라이버(사용자의 컴퓨터/PC/노트북에 음악 전송용).

• AVRCP(오디오/동영상 원격 제어 프로필) 드라이버(사용자의 기기에 대한 음악 건너뛰기/앞으로/일시정지/재생 명령 전송용)

반드시 사용자의 컴퓨터/PC/노트북용으로 제공되는 최신 드라이버 버전을 설치합니다.

올바른 드라이버(소프트웨어)를 다운로드하려면, 사용자의 컴퓨터/PC/노트북 제조업체의 웹사이트를 확인합니다. 일반적으로 ‘지원/다운로드’ 섹션에서 맞는 드라이버를 찾을 수 있습니다. 혹은, 해당 업체의 서비스 지원 센터에 연락하기를 권장합니다.

Microsoft/Windows 시스템에서 제공되는 표준 드라이버는 적합하지 않으며 오류 메시지가 표시되거나(PIN 코드를 입력해야 하는 등), 페어링이 작동하지 않습니다.
