The Anker Soundcore C40i Earbuds are part of Soundcore’s innovative open-ear lineup, delivering a flexible, breathable, and comfortable listening experience designed for active users. These clip-on earbuds stand out with their memory titanium joints, AI-enhanced mic system, and button-based controls—a welcome change for those who find touch controls unreliable. Whether you're jogging, biking, or working outdoors, the C40i aims to provide a secure, natural, and effortless listening experience.
The C40i adopts a breathable open-ear clip-on design that eliminates the pressure commonly felt with in-ear buds. This ensures comfort during extended use while still keeping your ears open to the surrounding environment—ideal for safety during outdoor activities.
Anker has enhanced the fit using 0.5mm memory titanium wires and TPU-based flexible joints, allowing the earbuds to bend and adapt effortlessly to the shape of your ears. With a tested 1,000-bend durability, the C40i promises both adaptability and long-lasting performance.
For even greater hold, especially during intense workouts, the included attachable ear grips add a layer of security that ensures the earbuds stay locked in place. Whether you’re on a sprint or a hike, they’ll stay put without constant adjustments.
The Soundcore C40i comes with AI-powered noise reduction and well-placed microphones that provide clear voice calls, even in bustling environments. This makes them great not only for entertainment but also for taking important calls on the go.
Instead of relying on sometimes-faulty touch controls, the C40i features physical buttons for managing music, volume, and calls. This makes them much more reliable for users who are often on the move or wearing gloves.
Rated IPX4, the C40i earbuds can handle light splashes and sweat—perfect for jogging, gym workouts, or light rain exposure.
Each earbud weighs just 5.8 grams, while the carrying case comes in at 59.2 grams, making the set ultra-portable and lightweight. It’s easy to carry in your pocket or bag without bulk.
Users can access the Soundcore app to customize EQ settings, control preferences, and even upgrade firmware—adding an extra level of personalization and long-term value.
The Anker Soundcore C40i Earbuds are competitively priced, typically ranging from $44.99 to $49.99, and are available on Amazon and other major online platforms. Considering their blend of comfort, build quality, and performance features, the pricing is well-aligned with user expectations in the mid-budget range.

The Anker Soundcore C40i is a compelling upgrade from previous models in the open-ear series. Designed with maximum adaptability, the flexible memory wire joints and lightweight build provide both comfort and a secure fit, especially for those who find traditional earbuds too invasive.
Sound quality is a strong point here—clear, natural, and expansive, making music and calls enjoyable in nearly any setting. The AI-enhanced microphones are surprisingly effective at cutting through background noise, which is a huge win for commuters and those working remotely outdoors.
The inclusion of button controls is also worth praising. They're responsive and more accurate than touch-sensitive alternatives, especially for users who are constantly on the move.
However, the default audio tuning may not suit every taste and could require tweaking in the app. Also, while the comfort is decent, some users may prefer softer earbud designs for long hours.
