Soundcore AeroFit 2 A3874 Open-Ear Earbuds, Bluetooth 5.4, IP55, 42-Hour Playtime

Open-ear earbuds keep the ear canal unobstructed, so you can listen while staying attuned to what is happening around you. The AeroFit 2’s adjustable ear hooks and rotating structure help you find a comfortable position for your ears.

Bluetooth 5.4 supports wireless listening with smartphones, tablets, laptops and desktops. The Minty Green finish adds a distinctive touch for everyday wear.

With up to 10 hours of playtime from a charge and up to 42 hours with the charging case, these earbuds are made to carry music and calls through a full day and beyond.

Key features

The 20 mm × 11.5 mm racetrack drivers, BassTurbo technology and LDAC support are designed to deliver deep bass, clear mids and vivid treble, with Hi-Res wireless audio. That combination gives playlists and other audio a full-bodied sound in an open-ear design. Real-time translation is also listed as a feature, alongside an app for managing the earbuds.

For calls, four beam-forming microphones work with an AI algorithm to pick up your voice and filter noise. This can be useful when taking a call while out walking or moving between daily tasks. Touch controls provide a direct way to manage playback and calls.

The included wireless charging case can be placed on a wireless charger, and the USB-C cable provides another charging option. An IP55 rating and sweatproof design support use during workouts and other active routines.

Fit and sizing

Soft, adjustable ear hooks and a double-curved surface are intended to make the fit easier to tailor, while the rotating structure adapts to different ear shapes. Because the earbuds sit outside the ear canal, they offer a different wearing experience from sealed in-ear models. Choose this open-ear style when keeping aware of nearby activity matters as much as having audio on.

Customer feedback often highlights sound quality and battery life, with some also appreciating the earbuds’ versatility. Fit, reliability and connectivity receive mixed reactions, so individual experiences vary. The adjustable hooks let you position each earbud to suit your ears.

Tips for day-to-day use

Pair the earbuds with a compatible phone, tablet, laptop or desktop over Bluetooth. For a day with a mix of music, calls and time outdoors, the open-ear design lets you listen while remaining aware of your surroundings. Use the touch controls for quick playback or call adjustments, and place the case on a wireless charger when you want a cable-free charging routine.

For longer listening sessions away from a charging point, the stated 10-hour playtime per charge and up to 42 hours with the case make the battery setup easy to plan around. The IP55 rating and sweatproof design also suit active use, while the four-microphone call system is there for voice conversations on the move.

Buying verdict

The AeroFit 2 suits listeners who want open-ear earbuds with adjustable hooks, wireless connectivity and a case that extends listening time. Its combination of Hi-Res wireless audio with LDAC, four-microphone calls, touch controls and sweatproof construction makes it a practical fit for everyday listening, calls and workouts—especially when staying connected to your surroundings is part of the routine.
