In-Ear Earbuds with 45H Total Playtime

These wireless earbuds use Bluetooth 5.4 and 13mm double-layer diaphragm drivers to deliver deep bass and clear stereo sound. Four ENC microphones enhance voice pickup for calls in noisy settings. The gold finish and IP7 waterproof rating suit daily commutes and workouts.

Suits listeners wanting long battery life

The case provides five extra charges for a combined 45 hours of playback, and each bud works independently for single-ear use. Buyers who need over-ear comfort or a wired connection will not find those options here. The 15 metre wireless range covers typical indoor movement.

Bluetooth 5.4 with 55ms latency

This version supports HID, HFP, A2DP and AVRCP profiles for stable audio and quick pairing. Auto reconnection activates when the case is opened. A 1.5 hour USB-C charge yields eight hours per bud, while a ten minute top-up adds two hours.
