Soundcore - Aero Fit 2 (Open-Ear Earbuds)

Soundcore AeroFit 2 Open-Ear Wireless Earbuds

General Description

Enjoy your music while remaining aware of the world around you with the Soundcore AeroFit 2 Open-Ear Wireless Earbuds. Designed for extended comfort, these earbuds rest outside the ear canal instead of sealing inside it, reducing pressure and allowing surrounding sounds to remain audible.

Each earbud features a four-level adjustable ear hook, making it easy to find a comfortable and secure position for different ear shapes. The dual-curved design distributes pressure evenly around the ear, making the AeroFit 2 an excellent choice for commuting, office work, studying, walking and light exercise.

Large 20 × 11.5 mm racetrack drivers, combined with Soundcore’s BassTurbo acoustic technology, deliver powerful bass, clear midrange and detailed treble. Support for Hi-Res Wireless Audio and LDAC provides enhanced wireless sound quality when used with compatible devices.

The AeroFit 2 delivers up to 10 hours of listening from a single charge, with the charging case extending total playback to as much as 42 hours. When time is limited, a quick 10-minute charge provides up to four additional hours of playback. The charging case also supports convenient wireless charging.

Four built-in microphones and AI-enhanced voice processing help keep conversations clear by identifying your voice and reducing unwanted background noise during calls. Bluetooth 5.4, multipoint connectivity and customisable touch controls complete a versatile open-ear listening experience.

Open-Ear Listening

Unlike conventional in-ear earbuds, the AeroFit 2 does not create a seal inside the ear canal. Sound is directed towards the ear while the canal remains open, providing a more breathable wearing experience and helping you remain aware of environmental sounds.

The open-ear design is particularly useful for:

• Walking and commuting

• Office work and studying

• Working from home

• Light exercise and gym sessions

• Listening around family or colleagues

• Users who dislike the pressure of traditional in-ear tips

Because the design remains open, it does not provide the same passive noise isolation as sealed in-ear earbuds.

Call Quality

The AeroFit 2 uses four microphones together with AI voice-processing technology to distinguish speech from environmental noise. This helps provide clearer conversations during phone calls, online meetings and voice chats.

Call performance may vary according to wind, background noise, fit, network quality and the connected device.

Battery and Charging

Enjoy up to 10 hours of playback per charge, with the charging case extending the total listening time to approximately 42 hours. If the battery is running low, placing the earbuds in the case for 10 minutes can provide up to four hours of additional playback.

The case can be charged using a USB-C cable or a compatible wireless charging pad. Battery life varies according to volume, audio codec, call usage and selected settings. Using LDAC may reduce the available playback time.

Water and Dust Resistance

The earbuds carry an IP55 rating, offering protection against sweat, dust and light rain. They are suitable for everyday activities and exercise but are not designed for swimming, showering or complete immersion in water.

The charging case is not covered by the earbuds’ IP55 rating and should be kept dry.

Important Information

• AeroFit 2 does not feature active noise cancellation.

• Open-ear earbuds allow environmental sound to remain audible and do not provide the same isolation as traditional in-ear models.

• Situational awareness can still be reduced when music is played at high volume. Always follow local road and workplace safety requirements.

• LDAC requires a compatible source device and may not be available on all smartphones, tablets or computers.

• Apple devices do not natively support LDAC and will normally use AAC.

• Multipoint and LDAC availability may depend on the connected devices and selected settings.

• Battery figures are based on laboratory testing; actual runtime varies according to volume, codec, calls and environmental conditions.

• The earbuds are water and dust resistant, but the charging case should be protected from moisture.

• Allow the earbuds to dry completely before placing them inside the charging case.
