EarFun has announced the Air Pro 4+, the first sub-$100 earbuds to combine Hi-Res Audio certification, dual-driver sound, adaptive ANC, and Auracast wireless audio sharing.
The new model is powered by Qualcomm’s QCC3091 chip and supports aptX Lossless, LDAC, Snapdragon Sound, and Bluetooth 6.0.
It also features Google Fast Pair, AI-enhanced call microphones, and QuietSmart 3.0 adaptive noise cancellation, which is capable of suppressing up to 50 dB of background noise.
The company says that its six-microphone AI-enhanced system ensures calls are crisp and natural.
EarFun’s dual-driver design combines a 10 mm dynamic driver with a FeatherBA balanced armature, which they say creates a richer, Hi-Res-certified sound profile. The company’s new Nano Side-Fitted Acoustic Architecture (NSAA) aligns the drivers at an exact 11-degree angle, improving treble clarity and reducing magnetic interference.
Battery life on the Air Pro 4+ offers up to 54 hours of total battery life, or 36 hours with ANC enabled, complete with wireless charging and a fast-charge function that delivers three hours of playback in just 10 minutes.
Designed from data gathered from 10,000 ear models, the Air Pro 4+ uses a three-point ergonomic fit and is rated IP55 for dust and water resistance.
Rocky Deng, EarFun’s CTO, said: “Through extensive testing, we discovered that setting an 11º angle between the two drivers minimises high-frequency attenuation caused by interference. This innovation delivers clearer, more natural highs, redefining what’s possible for earbuds under $100.”
The Air Pro 4+’s Auracast is included as part of the Bluetooth LE Audio standard, enabling a single-source device to broadcast to multiple receivers. This allows, for example, friends to share the same music stream or travellers to tune into airport announcements directly through their earbuds.
Award-winning designs for the Air Pro 4+
The Air Pro 4+ has already garnered multiple design awards, including the 2025 Red Dot Design Award, an IFA Innovation Award, and “Best of IFA 2025” titles from TechRadar, PhoneArena, and CHIP.
Available now via www.myearfun.com and Amazon, the EarFun Air Pro 4+ look set to redefine what consumers can expect from affordable wireless audio.
