Open-Ear Design for Active Use

The Amazfit Up A2427 earbuds sit on the ear rather than inside the canal, leaving the ear canal open to ambient sound. They are built for runners, gym-goers and commuters who want music or calls without losing awareness of traffic or conversation partners. At 43 grams the pair stays light during extended sessions.

Simple Pairing and Touch Controls

Removing the buds from the case initiates Bluetooth pairing with Android or iPhone automatically. Touch surfaces on the earbuds handle playback, volume and calls, and the controls are rated IPX4 against sweat and rain. A triple-tap summons the phone voice assistant, while Zepp Flow on a compatible Amazfit watch offers another hands-free route.

24-Hour Battery with Quick Recharge

The system delivers 24 hours of total listening time before the case needs a recharge. A full case charge takes 2 hours. The 20 hertz low-frequency response and 20 ohm impedance provide adequate headroom for podcasts, calls and background music, but bass-heavy tracks will hit the limits of the open-ear acoustic design.
