True wireless earphones for daily listening

The UMIDIGI TWS-4 delivers stereo sound and hands-free calls through Bluetooth 5.0. Each earpiece weighs 5.4g and measures 26x23x12mm. The charging case stores 450mAh and measures 92x40x31mm. Touch controls manage playback and calls without reaching for your phone.

Stable connection and consistent battery life

Bluetooth 5.0 maintains a link up to 10m with automatic reconnection after power cycles. A single charge provides 3H of music or 3.5H of talk time, while the case extends total listening across the day. Standby reaches 48H when not in active use. Gold-plated contacts and a high-elasticity cable ensure reliable charging.

Check your device and fit preferences

Verify your source supports Bluetooth 5.0 for full compatibility. The in-ear design uses a fixed nozzle; confirm this style suits your comfort needs. Calls rely on a built-in microphone with tuning for clarity. The compact case fits small pockets but requires a USB power source for recharging.
