Open the case to power on the earbuds and enter pairing mode. Select Soundcore C40i” from your device’s Bluetooth list.

FAQs

What kind of earbuds are the C40i?

The C40i are clip-on, open-ear earbuds that do not fit into your ear canal. Rather, they rest on the outer ear, allowing you to stay conscious of your surroundings and enjoy a breathable, “ear open” listening experience.

How’s the comfort and fit — will they stay secure during active use?

The C40i offers a stable yet comfortable fit with to its flexible memory titanium clip on frame and soft joint, which adjust to various ear shapes.

How is the sound quality — clarity, bass, music experience?

Surprisingly good for open ear earbuds: despite the earbuds’ inability to seal inside the ear, critics point out clear highs, wide mids, and solid bass.

Can I make calls and use them for meetings, outdoor errands, or commuting?

Indeed. Even in somewhat busy settings, the C40i’s dual microphones with AI-enhanced call clarity boost voice pickup.

What controls do they have — is it as convenient as touch earbuds?

For power, play/pause, track skip, volume up/down, and call management, they employ physical button controls (one per earbud) rather than touch.

How is the sound quality?

For open-ear designs, the earbuds provide good bass along with crisp mids and highs. They may not have the isolation and deep bass of in-ear earbuds, but the sound is well-balanced and enjoyable for calls, music, and podcasts. The listening experience can be improved by utilising the EQ and 3D sound features of the Soundcore app.

Can I use them for calls and meetings?

Indeed. The C40i’s twin microphones with AI-enhanced call clarity make them appropriate for online classrooms, video conferences, and phone conversations. Because of the open-ear design, background noise could still be audible.

How do they stay in place?

They employ a flexible memory-wire clip made of titanium that encircles the ear. They can be tailored to fit most ear shapes comfortably and securely thanks to adjustable ear grips.
