Ammunition has designed the Powerbeats Fit for Beats.

Powerbeats Fit is a second-generation true wireless earbud designed for both movement and everyday listening.

The design refines an in‑ear stabilisation system that uses a flexible wingtip to hold the earbud securely during activity – while remaining comfortable for long listening sessions.

This project focuses on balancing stability and portability, with the earbud geometry recalibrated to improve long‑term comfort and the charging case significantly reduced in size to make it easier to carry throughout the day.

Positioned between casual listening earbuds and high‑retention sports models, Powerbeats Fit supports both exercise and daily use within a compact form.
