EarFun Air Pro 4+ Review (2026): Flagship Codecs, Mid Price

This EarFun Air Pro 4+ review looks at a pair of true wireless earbuds that aims to deliver flagship-level codecs, such as aptX Lossless and LDAC support, along with adaptive noise cancelling, wireless charging and long battery life, at a mid-range price. It suits budget-minded listeners who want a feature-rich pair with long battery life and are willing to accept a few compromises on build and call quality.

This article is based on the manufacturer's specifications and on what independent expert reviews report. It is not based on hands-on testing by us. Across five expert reviews the earbuds average 8.5/10, so the overall picture is positive, with some clear caveats covered below.

EarFun Air Pro 4+ design and build

The earbuds and case together weigh 54g, and the case measures 60mm x 50mm x 28mm. The earbuds come in Black, White and Blue.

Reviewers describe the fit as light and comfortable, which matters for long listening sessions. The buds carry an IP55 rating for dust and water resistance. IP55 is not a submersion rating, so treat them as splash-resistant rather than waterproof.

The design is where reviewers are least enthusiastic. A common criticism is that the look is plasticky and generic, and that the case lid and hinge feel a little weak. The earbuds are built to a price, and the case is the part to handle with care.

Sound: dual drivers and codec support

Each earbud pairs a 10mm dynamic driver with a FeatherBA balanced armature driver. The manufacturer says this dual-driver layout delivers deep bass and crisp treble.

Expert reviewers generally describe the result as warm, rich bass with clear mids for the money. They also say that treble and soundstage are not class-leading, and that there is no spatial audio. If you like a full, enjoyable, bass-forward signature, the praise is encouraging. If you want an airy, analytical sound, it may feel a little restrained.

Codecs: the standout feature

Codec support is one of the strongest points of the spec sheet. The earbuds use Bluetooth 6.0 on a Qualcomm QCC3091 chip and support:

• aptX Lossless
• aptX Adaptive
• LDAC
• LC3
• SBC

The manual also lists AAC. In practice, a codec only helps if your phone or player supports it too. If your source device handles aptX Lossless or LDAC, you can get higher-quality streaming than the basic SBC codec allows. Reviewers single out this wide codec support as one of the model's strengths.

Noise cancelling: capable, not class-leading

The QuietSmart 3.0 system is an adaptive hybrid design rated at up to 50dB of noise reduction. Adaptive ANC adjusts to the noise around you rather than applying a fixed level. That is useful when you move between a quiet office and a busy street.

This is also the area where expert opinion is most mixed. Reviewers found the noise cancelling average in some tests, with lower rumble and high-frequency noise being the weaker areas. Those who need the strongest possible isolation, for example frequent flyers, should keep expectations measured.

Battery life and charging

Battery life is a major selling point. The manufacturer quotes:

• ANC on: up to 8 hours in the earbuds, and up to 36 hours with the case
• ANC off: up to 12 hours in the earbuds, and up to 54 hours with the case

The case has a 600mAh battery. The headline 54-hour figure assumes ANC is off, so expect noticeably less if you leave noise cancelling on all day. Even the ANC-on figure of 36 hours with the case means many people would only need to charge the case occasionally.

Charging is flexible. The case supports USB-C and wireless (Qi) charging. Fast charging is quoted at about 3 hours of playtime from a 10-minute charge. One of the manufacturer's own comparison tables lists a lower figure, so treat it as a rough guide. It is still a useful safety net when you are heading out the door.

Connectivity and everyday features

A lot of extras are packed in here, and several make daily use easier:

• Multi-device connectivity: reviewers mention multipoint support, so you can stay connected to more than one device, such as a phone and a laptop.
• In-ear detection: playback responds when you take the buds out or put them back in.
• Auracast: this Bluetooth broadcast feature lets compatible devices share or receive audio in venues or with other listeners.
• Low-latency mode: latency is rated at under 50ms, which helps keep audio in step with video when you are gaming or watching.
• AI translation: real-time AI translation is available through the EarFun Audio app.

The translation feature is a bonus rather than a reason to buy. The facts available do not go into detail on how it performs, so treat it as a convenience extra.

Call quality

For calls, the earbuds use a 6-mic AI array with cVc 8.0 noise reduction. On paper that is a strong setup. Reviewers, however, report that the microphones sound dull and thin in noisy environments. If calls are a core use case, particularly in loud places, this is a notable weakness.

What experts like and criticise

Reviewers consistently praise:

• the warm, rich bass and clear mids for the price
• the wide codec support
• the long battery life, up to 54 hours with the case with ANC off
• the inclusion of wireless charging, multipoint and Auracast
• the light, comfortable fit and IP55 rating

The common criticisms are:

• average noise cancelling in some tests
• a plasticky, generic design with a case lid and hinge that feel a bit weak
• dull, thin call mics in noisy settings
• treble and soundstage that are not class-leading, with no spatial audio

The scores reflect that balance. Tom's Guide gives it 4.5/5, SoundGuys 8.2/10, RTINGS 7.9/10, TechRadar 4/5 and Techaeris 9.3/10. The spread from RTINGS at the lower end to Techaeris at the top suggests that how much you value the feature set, as opposed to ANC and call performance, will shape how happy you are.

Who should buy it, and who should skip it

Buy it if you want a lot of features for a mid-range spend. That means high-quality codecs, wireless charging and up to 54 hours of playtime with the case (ANC off). It also makes sense if you prefer a warm, bass-rich sound and a comfortable, light fit. It suits budget-minded listeners who want feature-rich earbuds with long battery life, and the IP55 rating adds dust and water resistance.

Skip it if class-leading noise cancelling is your priority, if you want a premium-feeling case and finish, or if you take a lot of calls in noisy places. Anyone who wants spatial audio should also look elsewhere.

How it fits in its category

The Air Pro 4+ leans heavily towards features and battery life, and gives up some polish in build, ANC and call quality. If you are still comparing options, see our guide to the best wireless earbuds for alternatives with different strengths.

Verdict

The EarFun Air Pro 4+ makes a strong case for itself on features. It brings aptX Lossless, LDAC and LC3 support, up to 54 hours of playtime with the case, wireless charging and a light, IP55-rated fit to a mid-range pair of earbuds, with a warm and enjoyable sound that reviewers like. Its 8.5/10 average across five expert reviews reflects that. The compromises are real, though: average ANC in some tests, a plasticky case and weaker call mics in noise. If those trade-offs do not bother you, it is an easy earbud to recommend for the feature count. If they do, it is worth looking at rivals before you buy.
