EarFun Air Pro 4 Review: Budget ANC Earbuds That Deliver

You would never guess from looking at the slim EarFun Air Pro 4 just how much technology is packed inside. The earbuds sit securely, barely protrude from the ears, and deliver well beyond their price — which is the best news of all, because they are comparatively cheap for what they offer.

The Air Pro 4 come in four finishes — black, blue, matt white and glossy white. The practical stem design makes them especially easy to position, and they stay comfortable for long sessions without ever feeling like a foreign object. Five pairs of soft silicone ear tips cover different ear-canal sizes, and there is no rule that says both ears must wear the same size — if one canal is smaller, mix and match.

Stamina is a strength: over seven hours per charge at full volume with active noise cancelling engaged, with the case adding three full recharges plus roughly half of a fourth. Switch off ANC and the transparency mode and the buds run a full ten hours; lower the volume and they go further still.

Everything, including volume, is handled by touch gestures. Out of the box, a single tap lowers volume on the left and raises it on the right; a double tap on the left pauses or resumes; a triple tap skips back on the left or forward on the right; a long press cycles the noise-cancelling modes on the left or summons calls and the voice assistant on the right. All of it can be remapped in the companion app, and the touch surfaces can be disabled entirely — for one ear or both — which is handy for falling asleep to music without accidental taps. On calls, speech intelligibility is very good in both directions and transmission stays interference-free.

EarFun's app earns its keep. There are three primary modes — noise cancelling, transparency and normal — plus a low-latency game mode. Within ANC there are five options: deep cancelling for full isolation, a balanced setting for quieter surroundings, automatic adaptation to the environment, automatic adaptation to the ear (both AI-driven, using measurement microphones), and a dedicated wind-noise reduction. Transparency comes in a let-everything-through standard flavour and a voices-focused natural one.

The Air Pro 4 support aptX Adaptive, aptX Lossless and LDAC — codecs that transmit with little or, in the case of aptX Lossless, almost no loss. All are selectable in the app; enabling LDAC requires the buds to restart, after which they reconnect without fuss. LDAC costs some battery and nominally some range, though in normal indoor use there was no significant difference and no dropouts.

For tuning, the app offers a wealth of equaliser presets, plus a custom curve that can be saved as its own preset. Heard with all processing switched off, the EarFuns do not disappoint: bass lines arrive punchy with a gentle spring and a slight lift, giving the sound satisfying volume while leaving the mids and upper mids room to breathe. Only in outright resolution do they concede ground — and then only against considerably more expensive competition.

In short: the EarFun Air Pro 4 convince across the board. They deliver more sound and more features than the low price suggests, and their snug, comfortable fit should suit most ears. For budget noise-cancelling earbuds, they are an easy recommendation.
