Anker Soundcore C40i | Open-Ear Clip-On Earbuds with Flexible Fit, Button Controls, AI Clear Calls, Bluetooth 5.4

• Open-Ear Clip-On Comfort: The airy clip-on design sits on your ear without going into the canal, so you avoid in-ear pressure and stay aware of your surroundings. Each earbud weighs about 5.8g, and it fits comfortably alongside glasses. The flexible joints use a 0.5mm memory-titanium wire with soft TPU to adapt to different ear shapes, and the included ear grips (M and L) add stability during activity.
• Clear Sound and Clear Calls: Large 12×17mm drivers with a 20-degree angled sound outlet aim sound toward your ear canal with less leakage. The Soundcore app offers 3D sound, bass boost, and custom EQ, and dual microphones with AI keep your voice clear in noisy places.
• Physical Buttons and Long Battery Life: Real buttons give precise control of playback and volume with no accidental taps. You get up to 7 hours per charge and up to 21 hours with the USB-C charging case, and a 10-minute charge gives about 2 hours of playback. Bluetooth 5.4 with multipoint connects two devices at once, and IPX4 protects against sweat and splashes.
