FAQs & How-Tos

  • As with all in-ear headphones, our range of TWS headphones can be susceptible to a build up of dust and earwax. This can cause low volume on one or both earbuds, or balance issues (e.g. right earbud is louder than the left earbud). To reduce the likelihood of these issues occurring, it is a good idea to periodically clean your earbuds and your ears. Clean the earbuds by removing dust and wax after each use, using a pointed toothpick to remove larger amounts and a small amount of rubbing alcohol applied to a cotton swab for final degreasing.

    If you are experiencing volume or balance issues, always check for wax and dirt in and around the earbud and driver and complete cleaning of the earbuds as described above. If the issue persists, there may be earwax/dirt stuck in the small holes in the grille in front of the driver, preventing sound output. To resolve the issue try dipping the affected earbud tip into a solution of lukewarm tap water and a small amount of dish soap (washing up liquid). The earbud tip should only be put into the liquid up to a maximum depth of 1-2 mm only (see images below). Immersing the earbuds in water or putting the earbuds in water at a larger depth than this could void your warranty. Keep the earbud tip in the water for about 2-3 minutes, then wipe/clean the grille with a small brush (such as a toothbrush). The should remove the wax and resolve the volume/balance issues.

  • 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.
