Aesthetics.

The Enco Air4 showcases a sleek, minimalist aesthetic typical of OPPO, with a glossy finish on both green and white versions. The earbuds are slim and ultra-light (just 4.2g each), with ergonomics that ensure a snug, comfortable fit for long listening sessions. The matte texture ensures that the earbuds and charging case are wear-resistant and fingerprint-proof.

The charging case is compact and feels sturdy, magnetically securing the earbuds without adding bulk to your pocket or bag. I always loved the OPPO Enco Air series Earbuds’ case design, the fact that I can easily slip it in my shirt or pants pocket comfortably.

Performance.
OPPO Enco Air4’s 12.4mm drivers deliver a surprisingly robust soundstage. Bass is punchy but balanced, vocals and mids are clear, and the treble is crisp without sibilance. The sound signature leans slightly toward warmth, making it ideal for pop, hip-hop, and modern genres, but still versatile enough for classical or podcasts. When running “Can’t stand the rain” by The Rescues, I was enveloped in the three-dimensional auditory space. There was a clear separation of the different instruments and elements, while still feeling the openness of the track.
The adaptive ANC is outstanding at this price. It expertly suppresses city noise, transport rumbles, or chatty offices. The transparency mode is natural and adjustable, letting through just enough outside sound for safe awareness.
Call quality is another high point: the AI-powered mic array isolates your voice even on noisy streets, and low-latency mode keeps audio-video sync tight for gaming or streaming.
App Experience.
Setup with the OPPO HeyMelody app is quick and intuitive. Here, users can update firmware, adjust ANC/transparency, set EQ presets, and customize touch controls. The app’s interface is clean but isn’t as feature-rich as some competitors — advanced EQ fans may crave more manual control. Still, the basics are well-covered, and multipoint connectivity works reliably.
The Bottom Line.

The OPPO Enco Air4 exceeds expectations for its price, blending hi-fi sound, powerful ANC, marathon battery, and smart features in a refined design. Small misses like the lack of wireless charging and deeper EQ options don’t overshadow its core strengths. These are among the best-value flagship earbuds for 2024, whether you’re commuting, working out, or just need stellar all-rounders.
TLDR:
Great earbuds for your ears and wallet.
