Soundcore C40i Wireless Earbuds with Open-Ear Clip-On Comfort

A different kind of fit:

The Soundcore C40i use a clip-on open-ear design rather than silicone tips, so there is nothing pressed into the ear canal. The 0.5 mm memory titanium wire frame flexes to fit a wide range of ear shapes and the soft TPU joints hold their position throughout the day. The frame is rated for 1,000 bends, making it well suited to regular daily use.

Racetrack drivers and clear audio:

Inside each earbud sits a 12 mm x 17 mm racetrack dynamic driver with a titanium-coated diaphragm. The non-circular shape moves more air than a standard round driver of similar size, producing defined bass and clear mids. The anker soundcore C40i and its titanium-coated driver also contribute to a consistent frequency response from 20 Hz to 20,000 Hz.

Battery life and fast charging:

Each earbud holds 7 hours of playback on a single charge, with the USB-C charging case extending that to 21 hours total. Dropping the earbuds into the case for just 10 minutes restores 2 hours of listening time, so a quick top-up before leaving the house is usually enough.

Calls, connectivity and app control:

Two AI-enhanced microphones on the C40i work to reduce ambient noise during calls, making speech clearer in busier environments. Bluetooth 5.4 with multipoint connection lets the earbuds stay paired to two devices at the same time, switching between them without the need to manually reconnect. The soundcore app allows EQ adjustment, button remapping, battery monitoring and firmware updates.

Setup and Care

Getting started:

Open the charging case to power the earbuds on automatically. For first-time pairing, open the soundcore app or go to the Bluetooth settings on your phone and select "Soundcore C40i" from the device list. Multipoint pairing with a second device can be configured through the soundcore app once the first connection is established.

Fitting the earbuds:

Gently flex the memory titanium wire and clip the earbud over the outer ear so the driver faces the ear canal at the angled position. If a more secure fit is needed during activity, attach the included M or L ear grips to the earbud body for additional stability.

Charging:

Place both earbuds into the charging case and close the lid to begin charging. Connect the USB-C cable to the case to recharge it. The LED indicators on the case show the remaining charge level when the lid is opened.

Keeping the earbuds clean:

Wipe the earbuds and case with a soft, dry or slightly damp cloth after use. Do not submerge the earbuds or use cleaning sprays directly on the drivers or contacts. Store in the case when not in use to keep the contacts clean and the battery topped up.
