The verdict
The Anker Soundcore AeroFit Pro open-ear earbuds are designed with outdoor athletes in mind. The purpose of an open-ear design is to keep you aware of your surroundings while listening to music and exercising in busy environments. While the earbuds accomplish precisely this, it's important to remember the design prioritizes letting the outside world in over a full and immersive listening experience.
✓Liked: Secure fit, IPX5 protection rating, Allow you to maintain awareness naturally
✕Could be better: Lack of good-sounding preset EQs, Custom EQ is not very powerful, No "previous track" control option
