BTW-A3800

Hi-Unit launches a semi-custom print service on February 18, allowing logos or designs to be printed directly onto earphones starting from a single unit.

The service targets Hi-Unit earphones, initially supporting the BTW-A3800 model, and is available exclusively through the company’s official direct sales website.

Customers can order just one customized earphone, removing minimum lot restrictions and enabling flexible use for prototypes, commemorative items, or limited editions.
