Soundcore Aerofit 2 A3874 open-ear headphones

Open-Ear Headphones with Adjustable Fit

The Soundcore Aerofit 2 A3874 uses an open-ear design with double-curved ear hooks that rest outside the canal. Four adjustable positions adapt to over 99 percent of ear shapes for a secure, non-invasive fit. Weighing 85 grams, they suit runners, commuters and office workers who need to stay aware of surroundings while listening.

Upgrade from Sealed Earbuds for Awareness and Bass

Switching from traditional in-ear models removes the occlusion effect and lets ambient sound pass naturally. The jump is worth it when you need situational awareness outdoors or during calls. Racetrack drivers measuring 20 by 11.5 mm deliver twice the bass depth, while Bluetooth 5.4 and LDAC support stable Hi-Res streaming.

Check App Version and Charging Habits Before Buying

Real-time translation across 100 languages requires the Soundcore app at version 3.8.7 or later and the latest earbud firmware. The case provides 42 hours of total playtime and supports wireless charging, but the buds themselves run for 10 hours per charge. IP55 rating handles sweat and light rain, not submersion.
