Open-Ear Design for All-Day Comfort: soundcore AeroClip are open-ear clip-on earbuds that rest gently on your ears without sitting inside the canal, to reduce pressure and ensure comfort for all-day listening. Flexible, Secure Fit: With a flexible, memory titanium core and soft polymer exterior, AeroClip are tested to withstand 20,000 bends, adapt to different ear shapes, and naturally follow the contour of your ear, for a fit that's as secure as it is comfortable. Hi-Res Audio, Vibrant Bass: Enjoy Hi-Res audio and deep bass for detail-rich sound. Our advanced virtual bass technology powers out the lows, powered by a 12-milimetre titanium-coated driver for crisp, balanced mids and trebles. Note: Update the soundcore app to the latest version for the best listening experience. Directional Audio for Minimal Leakage: Directional acoustic tech guides sound precisely toward your ear canal, minimising sound leakage and keeping your audio private. Crisp, Clear Calls: Four microphones and advanced AI work together to filter out external noise and wind for crystal-clear calls. Be heard loud and clear no matter where you are, for conversations that sound like they're face-to-face. Note: soundcore AeroClip now boast an upgraded IP55 waterproof rating. Some early packaging may show an IPX4 rating, but the earbuds inside are actually rated at IP55.
