The true wireless earbud market is fiercely competitive, especially in the mid-range segment. OPPO, a brand known for its value-oriented audio products, is back with an update to its popular Air series. The OPPO Enco Air4 earphone promises an enhanced audio experience with larger drivers and a focus on core features. But does it stand out from the crowd? Let’s tune in and find out.
First Impressions: Familiar, Lightweight Design
The Enco Air4 continues the series’ tradition of a lightweight, semi-in-ear design. This style is a great middle ground for those who find fully in-ear silicone tips uncomfortable. They sit gently in the ear without deep insertion, making them ideal for long listening sessions. The charging case is likely compact and pocketable, emphasizing portability. While the design language may be familiar, the real upgrades are hidden within.
Key Features: Where the Enco Air4 Shines
OPPO has focused on improving the fundamentals with the Enco Air4. Here are the standout features that define this model:
-
New 12.4mm Large Dynamic Drivers: This is the headline upgrade. Moving to a larger 12.4mm driver (from the 12mm or smaller drivers in previous models) theoretically allows for richer, more powerful sound with deeper bass and clearer treble. OPPO claims this “New Sound Version” delivers a more balanced and immersive audio profile, which is crucial for music, podcasts, and movies.
-
AI Call Noise Cancellation: While not necessarily featuring active noise cancellation (ANC) for music listening, the Enco Air4 employs AI-powered noise cancellation specifically for calls. This means the built-in microphones use algorithms to isolate your voice and suppress background noises like wind or street traffic. The result is clearer phone and video calls, even when you’re in a noisy environment.

-
48-Hour Total Playback: Battery life is a strong suit. The earbuds themselves offer several hours of playtime on a single charge, but the real endurance comes from the charging case. With the case, you get a total of up to 48 hours of battery life. This is a significant advantage for travelers or those who frequently forget to charge their devices. Quick charging is also often included, providing hours of use from just a short charging session.
-
IP55 Waterproof Rating: The IP55 rating makes the Enco Air4 a reliable companion for workouts and commutes. This rating means they are protected against dust ingress and low-pressure water jets from any direction. In simple terms, they can handle sweat during intense exercise and light rain, offering peace of mind for active users.
-
Low-Latency Mode: For gamers and movie watchers, audio sync is critical. The Enco Air4 likely features a low-latency mode that reduces the delay between the video on your screen and the sound in your ears. This ensures a more synchronized and immersive experience when gaming or watching videos.

Who Are the OPPO Enco Air4 For?
These earbuds are an excellent choice for:
-
Comfort-Seekers: Users who prefer the feel of semi-in-ear earbuds over in-ear tips.
-
Value-Conscious Listeners: Anyone looking for a well-rounded pair of earbuds without a premium price tag.
-
Frequent Callers: People who need reliable call quality on the go.
-
Active Individuals: Thanks to the IP55 rating and lightweight design, they are great for the gym, running, or commuting.
-
Long-Haul Users: The massive 48-hour total battery life is perfect for those who are often away from a charger.

Final Verdict
OPPO Enco Air4 appears to be a thoughtful and solid evolution of the series. Instead of packing in every possible feature, OPPO has focused on core improvements: a larger driver for better sound, robust battery life, and reliable call quality.
For those who prioritize comfort, battery endurance, and clear calls, the Enco Air4 presents a compelling package. While audiophiles seeking ANC might look elsewhere, the Enco Air4 successfully carves out a space as a strong, value-driven contender perfect for everyday use, workouts, and long commutes. If you’re in the market for dependable, comfortable, and long-lasting earbuds, the OPPO Enco Air4 is definitely worth putting on your shortlist.
