Product Research
Features
Overview: The Soundcore AeroFit Pro (A3871) are advanced, lightweight open-ear earbuds that deliver high fidelity audio while allowing you to hear what's going on around you. The earbuds have large 16.2mm dynamic drivers for enhanced bass, and flexible ear hooks for a snug and secure fit. AeroFit Pro earbuds charge when placed in the provided charging case.
Bluetooth: The earbuds have Bluetooth version 5.3 with a 33-foot range and 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 Pro lets you connect up to two Bluetooth devices (multipoint) and switch between them in the Soundcore app. (Note: LDAC and multipoint cannot not be used together.)
Drivers: The AeroFit Pro earbuds feature oversized 16.2mm composite drivers with titanium-coated domes for crisp highs, rich midrange, and robust bass. BassUp Technology is a Soundcore algorithm that further magnifies low frequencies for deep, impactful bass. The open-ear design is non-intrusive, as there is nothing to insert into the ear canal. The drivers use air conduction technology, redirecting the sound waves toward your ears. There is very little sound leakage, so you're not disturbing others around you.
Earhooks: The earbuds are equipped with flexible earhooks that are made premium materials for all-day comfort. Each earhook features a 0.7mm thick, aerospace-grade titanium wire with a soft coating that can withstand up to 5,000 bends. This lets you achieve a snug, comfortable fit that keeps its shape.
Neckband: The earbuds come with a detachable neckband to give you even more security during rigorous activities. The ends of the earbuds fit into the holes at each end of the neckband to hold them in place. The neckband can be adjusted to length for best fit.
Microphones: AeroFit Pro 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 button controls for both music playback and phone calls. Whether you use both earbuds in TWS (true wireless stereo) or mono mode, you can play/pause, skip forward, skip backward, answer/end call, and reject calls. 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 Pro earbud is equipped with a 105mAh 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 2 hours. With a fully charged battery, the earbuds provide approximately 14 hours of playtime. The charging case battery stores enough energy to recharge the earbuds over two additional times for a total of 46 hours of music playback. A quick 10-minute charge should provide about 5.5 hours of playtime.
Spatial Audio: The Aerofit Pro earbuds use multiple sensors to provide dynamic head tracking and true Spatial Audio for an immersive listening experience. You can enable Spatial Audio in the Soundcore app.
SweatGuard: The earbuds are safe to use during workouts. Soundcore's exclusive SweatGuard technology protects the drivers and internal components from damaging moisture, earning an industry-leading IPX7 waterproof rating.
Soundcore App: The Soundcore app supports the AeroFit Pro 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 11.0 or later. It is also compatible with Android devices running Android OS version 7.0 and up.

The only reason I can't give 5 stars is comfort. I wear glasses, these tend to hurt my ears a bit
