Oppo has unveiled the Enco Air5s, the brand’s first semi-in-ear earbuds with Active Noise Cancellation, placing them in direct competition with Apple’s AirPods 4 with ANC.
The open design that gives semi-in-ear earbuds their comfortable fit has traditionally been a poor fit for effective noise cancellation, since it leaves more room for ambient sound to leak through.
Oppo’s Real-time Adaptive Noise Cancellation addresses that limitation by adjusting noise reduction based on fit, ear canal shape and surrounding sound, all processed through an 800kHz sampling rate for faster response to changing conditions.
Alongside that adaptive system, the Enco Air 5s also include a Tailored Voice-Canceling System built to suppress vocal frequencies and reduce nearby conversations, a feature aimed at noisy environments such as crowded cafés.
Each earbud weighs just 3.9 grams, a figure Oppo credits to its Excimer Craftsmanship finishing process, which combines a shimmering surface with a smooth touch while keeping the overall build ultra-lightweight. Complementing this is the Ergonomic Semi-in-Ear Fit, intended to conform more closely to natural ear contours and reduce friction during extended wear.
Sound comes from a newly customised 12mm dynamic driver built around a Copper-Clad Aluminum Wire coil, paired with an Acoustic Cavity Design that Oppo says delivers crisp highs, impactful bass and clear vocals. An upgraded 10-band Custom EQ allows listeners to fine-tune low, mid and high frequencies, while Adaptive Sound Enhancement compensates for sound leakage in real time.
Connectivity is Bluetooth 6.0 alongside Oppo’s own Smart Bluetooth system, with Dual Connection Across Systems letting users switch between paired devices without manually reconnecting.
Beyond standard pairing, the earbuds introduce AI Translate, supporting face-to-face translation for situations such as ordering food or attending meetings abroad, alongside Slide Volume Control for hands-free adjustment without touching a connected phone.
Battery life reaches up to 48 hours with the charging case, with Oppo stating the cells retain over 80 percent capacity after 1,000 charge cycles, a claim backed by TÜV Rheinland certification.
The Enco Air 5s will launch in Lunar White, Midnight Black and Starlight Purple finishes, though Oppo has not confirmed pricing or release dates beyond noting that details will follow through official local market announcements.
