Oppo Enco Air5s Unveiled: Exciting 12mm Drivers, 48H Battery & Bluetooth 6.0

Key Highlights

• Real-time adaptive ANC technology
• Up to 48 hours total battery life
• IP55 water and dust resistance
• AI voice & translation features

OPPO is stepping into a new direction with the Oppo Enco Air5s, its first semi-in-ear true wireless earbuds. Instead of silicone tips that go deep into the ear canal, this design sits more gently in the ear—something that instantly makes long listening sessions feel less tiring.

What stands out immediately is how OPPO is trying to balance comfort with intelligence. Semi-in-ear designs usually struggle with noise isolation, but here the company is clearly relying on adaptive software to make up for the physical gap.

Interestingly, this approach makes the earbuds feel more “open,” yet still smart enough to adjust to your surroundings in real time.

 Price & Availability

Design & Comfort

The Oppo Enco Air5s focuses heavily on comfort-first design. At just 3.9 grams per earbud, they are among the lightest in their category, and honestly, you can feel that difference the moment you put them on.

Because there’s no silicone tip, there’s less pressure inside the ear canal. That makes them ideal for people who dislike the “plugged-in” feeling of traditional earbuds. What stands out is how naturally they sit—even during walking or light workouts.

That said, the semi-open design does mean you lose some passive noise isolation, which is where OPPO’s software comes into play.

Audio Performance

The 12mm drivers deliver a sound profile that feels lively rather than overly flat. Vocals come through clearly, and there’s a noticeable boost in bass compared to older semi-in-ear earbuds.

Interestingly, the tuning feels slightly consumer-friendly—meaning it leans toward enjoyable rather than analytical sound. That’s actually a good thing for casual listeners.

At higher volumes, separation holds up reasonably well, though it won’t match premium in-ear sealed designs. But for daily music, YouTube, and podcasts, it performs comfortably.

ANC & Smart Noise Control

This is where things get interesting.

The real-time adaptive ANC system constantly adjusts based on how the earbuds sit in your ears and the surrounding noise. So instead of one fixed mode, it actively reacts to your environment.

There’s also a voice-cancelling system designed specifically to reduce nearby conversations. Honestly, this is useful in real-world situations like cafés or public transport where human voices usually cut through normal ANC.

It won’t completely silence everything like high-end flagship earbuds, but for a semi-in-ear design, it’s surprisingly capable.

Battery Life

Battery life is one of the strongest parts of the Oppo Enco Air5s.

• Up to 9 hours per charge (no ANC)
• Around 4.5 hours with ANC on
• Up to 48 hours total with case

What stands out is how OPPO has optimized standby and case efficiency. Even with ANC enabled, the total endurance is still quite practical for daily use.

Features & Connectivity

OPPO has packed a lot of smart features into this compact design:

• Bluetooth 6.0 for stable connection
• Dual-device pairing
• Slide volume control
• AI translation support
• Digital assistant integration
• Spotify quick launch

That’s actually impressive because these features usually appear in higher-end models.

Final Verdict

The Oppo Enco Air5s feels like OPPO’s experiment in making semi-in-ear earbuds smarter rather than just louder or more isolating.

If comfort is your top priority, this is one of the most practical designs in this category. The adaptive ANC and long battery life make it more versatile than typical semi-in-ear options.

However, if you want maximum noise cancellation or deep bass isolation, traditional in-ear earbuds will still perform better.

For everyday users, though, this is a refreshing and very usable upgrade.
