Cleaning Instructions for Re-establishing Charging

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.
