Open-ear headphones with adjustable hooks

Soundcore AeroFit 2 A3874 headphones sit outside the ear canal using a double-curved, open-ear design that keeps you aware of surroundings. Four adjustable ear-hook positions fit over 99 percent of ear shapes. Bluetooth 5.4 and LDAC deliver Hi-Res audio through 20 mm × 11.5 mm racetrack drivers with BassTurbo for richer bass.

Ideal for outdoor listeners and multilingual users

Runners, commuters and office workers who need situational awareness will appreciate the non-invasive fit and IP55 water resistance. Real-time translation across 100 languages via the Soundcore app suits travellers and meeting participants. Buyers who want active noise cancellation or in-ear isolation should consider a different style.

42-hour total playtime with wireless charging

Each charge provides 10 hours of listening, and the case extends that to 42 hours. The case supports wireless charging for cable-free top-ups. Multipoint Bluetooth lets you stay connected to two devices at once. Heavy bass enthusiasts may find the open-ear architecture limits low-end impact compared with sealed designs.

Questions about this item

Does my phone need to support Bluetooth 5.4 to pair with the AeroFit 2?

The headphones use Bluetooth 5.4 but remain backward compatible with earlier Bluetooth versions, so they will pair with any phone that supports standard Bluetooth audio profiles.

Will the open-ear design and 20 mm × 11.5 mm racetrack drivers still let me hear my surroundings clearly while I listen?

Yes, the open-ear architecture leaves the ear canal unblocked, and the directional acoustic system focuses sound toward your ear so you stay aware of ambient noise.

How can I confirm the real-time translation feature is active after I set up the Soundcore app?

Update the app to version 3.8.7 or later and the earbud firmware to the latest release, then open the translation mode in the app — the interface will show the selected language pair and a live transcript while you speak.
