JBL Endurance Race TWS

In most cases when a Computer/PC/Laptop has issues connecting to a Bluetooth device (Portable speaker, Headphones, Active speakers), it's caused by your Computer/PC/Laptop's Bluetooth driver (software).

The driver (software) should support the following Bluetooth protocols, to be able to play music/sound from your Computer/PC/Laptop:

• A2DP (Advanced Audio Distribution Profile) driver for your Computer/PC/Headphones to transfer music.

• AVRCP (Audio/Video Remote Control Profile) driver to send skip/forward/pause/play music to your device

Always get the latest driver version available for your Computer/PC/Laptop.

To download the correct driver (software), visit the manufacturer's website of your Computer/PC/Laptop. They usually have a "Support/Download" section where you can find the correct driver. Otherwise, we advise you to contact their support.

The standard drivers provided by Microsoft/Windows system are not correct and will result in error messages (such as having to enter a PIN code), or pairing will not work.

The two earpieces of your TWS headphones should normally be connected together without issue.  However, if they are no longer paired to each other, please follow these steps, in order.

1. Forget/unpair the headphones on your device.
2. Manually pair the two earpieces together following the "Manual Pairing Left & Right" instructions in your Owner's Manual/Quick Start Guide.
3. Pair the headphones to your device and see if this resolves the problem.
4. If manual pairing does not fix the problem, forget/unpair the headphones on your device again.
5. Initiate a Product Reset to reset the earbud’s Bluetooth connection.
   • Note that RESET will wipe all previous settings and pairings, so it will be necessary to pair your headphones with your devices again
   • Follow the Product Reset instructions in your Owner's Manual/Quick Start Guide.
   • Manually pair the 2 buds together again, as you did in step 2.  This additional step is necessary because, by default, the reset procedure does not automatically pair the two ear pieces together, but it does wipe all previous settings and resets the internal processor, so it is necessary to manually pair the two ear pieces together again.
   • Pair the buds to your Source Device.

True Wireless 헤드폰의 충전 문제는 흔히 발생합니다.
때때로 충전이 중단될 수 있습니다. 충전이 아예 시작되지 않거나 이어 버드 한쪽의 전원이 갑자기 켜지고 페어링 절차가 시작되는 경우가 발생할 수 있습니다.

이는 거의 대부분 충전 접촉부의 오염이 원인입니다. 
이러한 접촉부는 취약한데 땀, 피부 유분이나 귀지로 쉽게 오염될 수 있기 때문입니다.
대개 금도금이 되어 있으나, 금도금은 표면 오염을 막지는 못합니다.

충전 문제가 발생하면, 우선 각 이어 버드 양쪽과 충전 케이스의 모든 접촉부를 늘 깨끗하게 해야 합니다.
미세한 구멍까지 닿기는 쉽지 않을 수 있으나, 일반 면봉이나 메이크업용 면봉을 사용하면 됩니다.   끝을 소독용 알코올로 살짝 적신 다음, 각 접촉면에 가볍게 문질러서 닦아냅니다.
접촉부가 깨끗해 보일 때까지 반복하면, 충전이 제대로 작동됩니다.

There are several easy ways to prevent damage to your headphones, and please follow the steps below.

1. If the USB port has a cover, please always have it covered, except when charging.

2. Always be sure the USB port and connector are dry before connecting to charge.

3. Do not allow any oils, stains, sweat, or corrosive materials to contact the charging port. It will eventually damage the port.

4. Do not damage or block the USB port. For example, do not force it in if you have trouble inserting the USB connector into the port. Instead, examine the port and remove foreign substances that might be inside or blocking the port.

If you need more assistance, please contact the Customer Service team.
 

This product is rated IP67, which is different from IPX7. IP67 protects the product from submersion in 1 meter (3.3 feet) of water for up to 30 minutes. It is also resistant against dust. Dust accumulation around electronics can lead to hardware failure, so the IP67 rating is an extremely beneficial addition to this product. 

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.

1. First, try to restart the Bluetooth connection on your source device (Smartphone/tablet/PC) by switching Bluetooth off and on again with a short pause in between.

2. "Forget" (remove) the previously paired connection (on your smartphone/tablet/PC) in your Bluetooth settings if you had once paired with your product.

3. Try to restart the source device (Smartphone/tablet/PC) by powering it off and on again and after restarting, try to establish a Bluetooth connection to your product.

4. If the above does not work, then try to restart your product (Portable speaker, Headphone) by turning it off and on again.

5. Press and hold down the Bluetooth button on your device (Portable speaker, Headphones) to initiate pairing mode again.

6. Go into the Bluetooth settings on your Smartphone/tablet or PC to start the pairing process.

You should now have a successful pairing with your device. If you are still experiencing issues, please contact us again.

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.

• Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.

• Try to shutdown other products that have Bluetooth, but are not being used. They are often the reason for interference even though they are not being used.

• Do not stand too close to your Wi-Fi router since a Wi-Fi signal is stronger and in many cases will "overlap" the connection.

• Be aware of walls around you. Concrete and brick walls will often interrupt the signal, as it cannot pass through such thick walls.

• Bluetooth signals cannot travel through water, which includes the human body. Make sure with wireless headphones to keep your source device and the receiver on the same side of your body.

• Open spaces such as parks can cause issues for your devices, as open air is "bad" for any Bluetooth signal if it cannot reflect from objects around you.

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.
