Oppo Enco Air 4s ANC Earbuds Launch with 32 dB ANC and 43 Hours

The Oppo Enco Air 4s ANC earbuds have launched in China for 179 yuan, offering active noise cancellation and long battery life at a budget price. Positioned below the Enco Air 5, they feature 12.4mm dynamic drivers, transparency mode, AI call noise reduction and up to 43 hours of total playback.

The key details are straightforward: 32 dB ANC, IP55 protection, and fast charging that can add up to 4 hours of listening from a 10-minute charge. For buyers comparing low-cost wireless earbuds, that mix of features is the main story here, especially since the price stays firmly in entry-level territory.

Oppo Enco Air 4s adds IP55 protection and all-day call features

The Oppo Enco Air 4s is built as an IP55 rated TWS earbud set, which gives it protection against dust and water exposure in everyday use. Oppo also says the earbuds were tested for heat, drops, and repeated case use. That kind of durability testing is worth noting in this price segment, where many affordable models focus on features first and practical toughness second.

Call quality is another clear part of the pitch. The earbuds use two microphones along with AI call noise reduction, which should help with voice pickup in busy places. That makes them a better fit for commuters and students, two groups that often use budget earbuds for long stretches and in noisy environments. The focus is not on premium extras here. It is on making the basics feel more dependable.

The audio hardware also looks familiar in a good way. Oppo has included 12.4 mm dynamic drivers, which usually point to a larger sound-producing unit than what you find in some ultra-cheap wireless earbuds. The Enco Air 4s also supports transparency mode, so users can hear outside sounds without removing the earbuds. In practice, that gives the product a more complete feature set than the price alone might suggest.

Sea Blue and Rock Black finish the Oppo Enco Air 4s price story

Battery life is one of the strongest claims attached to the Oppo Enco Air 4s. Oppo says each earbud can last up to 12 hours with ANC turned off, and the total runtime reaches 43 hours when paired with the case. A 10-minute charge can add up to 4 hours of playback, which is useful for quick top-ups before leaving home or heading to work.

These numbers place the earbuds in a competitive spot for budget buyers who want convenience without stepping up to a more expensive tier. The 32 dB ANC claim is especially important because it gives the Enco Air 4s a clear headline feature. In the entry-level TWS market, active noise cancellation is still often treated as a compromise or limited add-on. Here, it is one of the main selling points.

Color options are simple, with Sea Blue and Rock Black available at launch. That keeps the product story focused on value rather than design variety. Oppo’s approach is easy to read: deliver the practical features buyers ask for most, keep the pricing low, and avoid pushing the model into midrange territory. For shoppers comparing affordable ANC earbuds, the Enco Air 4s fits neatly into that gap.

At 179 yuan, the Oppo Enco Air 4s sits in a space where every feature has to justify itself. The combination of ANC, long battery life, IP55 protection, and AI call noise reduction gives it a stronger case than many basic wireless earbuds. It does not try to be a premium product. It tries to be a well-equipped one at a low price, and that is probably the point.
