Product Research
Features
Overview: The Soundcore AeroFit 2 (A3874) are advanced, lightweight open-ear true-wireless earbuds that deliver high fidelity audio while allowing you to hear what's going on around you. The earbuds have unique 20mm x 11.5mm racetrack dynamic drivers and BassTurbo technology for rich sound with enhanced bass. AeroFit 2 earbuds charge when placed in the provided charging case. The Soundcore AeroFit 2 earbuds are covered by an 18 month limited warranty.
Bluetooth: The earbuds have Bluetooth version 5.4 with SBC and AAC codecs. For Android devices with version 8.0 or later, you can enable the LDAC codec in the Soundcore app for higher quality audio. LDAC enables the transmission of 3x more audio data than standard Bluetooth (SBC) at a maximum bitrate of 990 kbps. AeroFit 2 lets you connect up to two Bluetooth devices (multipoint) and switch between them in the Soundcore app.
Drivers: The AeroFit 2 earbuds feature 20mm x 11.5mm racetrack drivers that deliver crisp highs, rich midrange, and robust bass. BassTurbo technology is a Soundcore-engineered, hourglass-shaped structure that intensifies the vibration of the diaphragm to enhance the lower frequencies for deep, impactful bass.
Comfort-built: The AeroFit 2 Open-Ear Wireless Earbuds have a non-intrusive, open-ear design with air-conduction technology for comfortable, all-day wear. The earbuds feature a double-curved surface that evenly distributes pressure wherever they touch, and a soft liquid silicone coating that is gentle to the skin. The thin, downward tilting ear hooks are perfect for eyeglass wearers, as they don't interfere with the eyeglass temples. The rotating ear hooks offer four positions (LV1 through LV4), allowing you to find a comfortable fit for any size of ear.
Water and Dust Resistant: The earbuds are built-to-last with resistance to water, dust, and sweat. Soundcore's proprietary SweatGuard technology gives the earbuds an IP55 ingress rating, protecting its inner circuitry from damage caused by liquid or dust entering the earbud cavity.
Microphones: AeroFit 2 features four microphones, two per earbud, for crystal clear phone calls. These beamforming mics combine with AI to enhance your voice and separate the noise of a busy environment.
Onboard Controls: The earbuds have a small touch-sensitive area around the Soundcore logo for controlling music playback, phone calls, volume, and activating your phone's Voice Assistant. If you use both earbuds in stereo mode, you can play/pause, skip forward, skip backward, answer/end call, and reject calls. In mono mode with a single earbud, you can play/pause, and answer, end, or reject a call. In the Soundcore app, you can enable volume control and activate your phone's native voice assistant, assigning them to your earbud controls.
Batteries: Each AeroFit 2 earbud is equipped with a Lithium-ion rechargeable battery, while the charging case has a 750mAh rechargeable battery. The earbuds can charge from 0% to 100% in about an hour while inside the case. The charging case charges via USB (5V 1.2A) in approximately 1.7 hours, while the charging case and earbuds together take about 2.2 hours to charge. The case can also charge wirelessly when placed on a Qi-certified wireless charging pad. It takes about 2.6 hours to charge the charging case and earbuds wirelessly. With a fully charged battery, the earbuds provide approximately 10 hours of playtime. The charging case battery stores enough energy to recharge the earbuds over and over for a total of 42 hours of music playback. A quick 10-minute charge should provide about 4 hours of playtime.
Soundcore App: The Soundcore app supports the AeroFit 2 earbuds, as well as dozens of other Soundcore products. The app can help you personalize and optimize your listening experience. You can also keep your earbuds up to date with firmware updates, when available. The app is compatible with iPhone and iPod touch, and requires iOS version 13.0 or later. It is also compatible with Android devices running Android OS version 7.0 and up.
