FAQs & How-Tos
Headphones & Third Party Communication Apps (Skype, Zoom, WhatsApp, etc)
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.
Is Volume Control Supported?
This headphone does not feature volume control. You must manually control volume from your device.
Cleaning Instructions for Re-establishing ChargingIt 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.
How to Factory Reset True Wireless Stereo EarbudsDouble-tap the button on the right earbud, then on the third tap - press and hold the button for more than 5 seconds (until the unit shuts off).
This restores the earbuds to the factory defaults.
TWS must be connected to perform the reset, so neither of the earbuds should be off or in the charging case.
It also may be necessary to remove or forget the earbuds from the list of paired Bluetooth devices in order to pair again.
Pairing issues with a Computer or PCIn 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.
