OPPO Launches Enco Air5s, Its First Semi-In-Ear Earbuds with ANC

SHENZHEN - OPPO announced OPPO Enco Air5s, the brand's first semi-in-ear earbuds with Active Noise Cancellation (ANC). Backed by Real-time Adaptive Noise Cancellation Technology and a Tailored Voice-Canceling System, Enco Air5s delivers a personal, immersive listening experience across a wide range of scenarios. Featuring an ultra-light 3.9 g ergonomic fit per earbud, a 12 mm dynamic driver, and a range of AI-enabled features, Enco Air5s makes every day listening smarter, clearer, and more effortless, a press release stated by OPPO. 

"At OPPO, we are committed to bringing together elegant design and advanced technology," said Daryl Zhang, Product Manager of Enco Air5s. "Comfort should never come at the expense of performance. With Enco Air5s, we set out to integrate powerful ANC into a lightweight semi-in-ear design, creating a quieter and more comfortable listening experience that users can enjoy throughout the day."

A Quieter Space, Designed Around You

While semi-in-ear earbuds are widely appreciated for their barely-there comfort, their open acoustic design makes achieving effective ANC more challenging. Enco Air5s addresses this challenge by bridging the advantages of a semi-in-ear design and advanced ANC performance.

Enco Air5s debuts OPPO's flagship-grade Real-time Adaptive Noise Cancellation technology, which intelligently adjusts noise reduction based on how the earbuds are worn, ear canal shape, and the surrounding noise, all in real time. With an 800 kHz sampling rate, it responds more quickly to changes in ambient sound, resulting in more effective and stable noise cancellation performance. Whether during the rush-hour commute or quiet time before bed, Enco Air5s delivers consistently optimized and comfortable noise reduction across everyday scenarios.

Furthermore, a Tailored Voice-Canceling System is designed to enhance vocal-frequency suppression to reduce surrounding conversations. By combining a custom-engineered noise-cancelling acoustic architecture with specially tuned algorithms, the earbuds effectively create a distraction-free listening space even in places like crowded cafés.

Subtle Glow, Effortless Comfort

Beyond advanced noise cancellation, Enco Air5s also embodies OPPO's pursuit of refined aesthetics and thoughtful design.

Featuring Excimer Craftsmanship, the earbuds combine a delicate shimmering finish with a smooth, refined, and comfortable touch. Each earbud weighs just 3.9 grams1, delivering an ultra-lightweight wearing experience with minimal burden. Complementing this is the Ergonomic Semi-in-Ear Fit Design, which allows the earbuds to better conform to the ear contours, reducing friction and strain for enhanced long-term comfort.

Flagship Sound, Made for Everyday Listening

Enco Air5s is equipped with a newly customized 12 mm dynamic driver, featuring a high-grade Copper-Clad Aluminum Wire (CCAW) coil. Underpinned by proprietary Acoustic Cavity Design, Enco Air5s delivers crisp highs, impactful bass, and clear vocals for a vivid and engaging listening experience.

Meanwhile, Adaptive Sound Enhancement intelligently compensates for sound leakage and optimizes different frequency bands, delivering a fuller and more immersive sound. For deeper personalization, the upgraded 10-band Custom EQ enables more precise adjustment across low, mid, and high frequencies, making it easy to tailor the sound signature to individual preferences.

Seamless Connectivity, Reliable Durability

Equipped with the latest Bluetooth® 6.0 technology and powered by OPPO Smart Bluetooth2, Enco Air5s delivers a stable and reliable wireless connection. Dual Connection Across Systems further enables effortless switching between multiple devices without the need for manual reconnection.

In addition, Slide Volume Control allows users to intuitively adjust volume without touching their phone. The voice assistant and Spotify3 can also be launched with a simple gesture, enabling hands-free access to music and information. New on Enco Air5s, AI Translate4 supports face-to-face translation and simultaneous interpretation, ideal for cross-language communication such as ordering food or attending meetings overseas.

Equally impressive is the battery life, designed to power your experience all day, with up to 48 hours5 of total playback using the charging case. Engineered for long-term durability, the battery retains over 80% of its original capacity after 1,000 charging cycles and has earned TÜV Rheinland Battery Durability Certification.
