Why do I have to use the charging clip to charge my earbuds?

The X4 earbuds have been designed to prevent any damage from liquids, including water and sweat. This sealed earbud design requires the use of the charging clip to ensure the correct charging pin contacts are made during charging. Because of this, the charging clip must be used to charge the earbuds.

N.B. The charging clip is not water resistant, so please ensure your earbuds are completely dry before charging.
