Diagnostic FAQ

Why does one earbud stop charging in the case?

One earbud typically stops charging due to skin oils or oxidation coating the gold-plated pogo pin contact pads on the earbud stem or inside the case well. Cleaning both contacts with a microfiber tip or cleaning pen immediately restores electrical connection.

How can I prevent earbuds from constantly falling out during exercise?

Earbuds fall out because standard silicone tips slip when ear canal moisture increases. Upgrading to viscoelastic memory foam tips (such as Comply Core 500) expands to grip the unique contours of your ear canal, creating 30x more grip than silicone.
