Anker Soundcore C40i Open-Ear Clip Earbuds Bluetooth 5.4 – Waterproof, 21h Battery, Dark Gray

In-ear earbuds hurt after an hour and cut you off from the world — even worse when running or cycling. The Anker Soundcore C40i in Dark Gray solve this with an open-ear clip-on design: clips around the ear without pressure, lets ambient sound through, and stays steady even during intense exercise thanks to a 0.5 mm memory titanium wire that adapts to your ear shape. Bluetooth 5.4, 21 hours of battery, and AI call clarity — all day without charging.
