OPPO Enco Air5s Review: Semi-In-Ear Earbuds that Balance Comfort and Smart Noise Canceling

Oppo launched the Enco Air5s semi-in-ear earbuds on June 25, 2026, featuring a hard-plastic shell, Bluetooth 6.0, and adaptive noise cancellation. Priced at approximately $44 (CNY 329), the buds weigh 3.9 grams and offer up to 48 hours of total battery life with the charging case, according to Android Headlines.

The Enco Air5s departs from traditional earbud designs by replacing silicone tips with a smooth, hard-plastic shell. This semi-in-ear architecture aims to eliminate the pressure associated with rubber seals during long listening sessions, Android Headlines reports.

Each earbud weighs 3.9 grams. Despite the open-ear design, Oppo equipped the chassis with an IP55 rating for protection against dust and water splashes.

How does the Enco Air5s handle background noise?

Oppo utilizes a real-time adaptive noise cancellation (ANC) framework to compensate for the lack of a physical rubber seal. According to Android Headlines, the system samples external sound waves at a rate of 800kHz to adjust frequencies based on the user’s ear canal shape and environment.

For voice communication, the hardware includes a triple-microphone array. This system uses specialized algorithms to filter wind interference and background chatter in office environments.

Audio is delivered via a 12mm dynamic driver. Users can modify sound profiles through a 10-band equalizer found in the HeyMelody companion app.

What connectivity and smart features are included?

The earbuds use Bluetooth 6.0, which supports a dual-device connection. This allows a user to stay paired with a phone and a laptop simultaneously, Android Headlines reports.

The touch-sensitive stems provide several control options:

• Vertical swipes to adjust volume.
• Double-taps to trigger a remote camera shutter.
• Shortcuts to activate digital assistants.

The system also supports real-time AI translation for immediate audio dubbing during travel.

What are the battery life and pricing details?

Battery performance varies based on the use of noise cancellation. When ANC is disabled, the earbuds provide 9 hours of playback on a single charge, totaling 48 hours with the charging case. With adaptive ANC enabled, the single-charge life drops to 4.5 hours, with a total of 25 hours including the case, according to Android Headlines.

The Enco Air5s starts at CNY 329 (roughly $44) in China. Oppo has begun rolling out the product across Mexico and Southeast Asia, though final pricing may vary by region.

This release positions the Air5s as a budget-friendly alternative for users who prioritize the comfort of an open-ear fit over the complete isolation provided by traditional silicone-tipped earbuds.
