Our story
It started with a worn-out headphone cushion.
We rented a narrow shop and fixed what people brought in: cracked cushions, tired batteries, buds that only played on one side.
Customers kept asking what they should buy instead. So we started selling only the gear that had already survived our bench. That rule never changed.
