Key Features

Hybrid Dual-Driver System – Precision-Tuned Sound

The EarFun Air Pro 4 Plus features an advanced hybrid acoustic system combining two specialised drivers.

• 10mm Composite Dynamic Driver: Delivers deep, powerful bass and rich midrange performance.
• FeatherBA™ Balanced Armature Driver: Reproduces detailed high frequencies, clear vocals and intricate musical textures.

Working together, these drivers provide a balanced, engaging listening experience with improved separation and clarity across a wide range of music genres.

Nano Side-Fitted Acoustic Architecture (NSAA™)

EarFun's innovative Nano Side-Fitted Acoustic Architecture positions the FeatherBA™ balanced armature at an 11-degree angle relative to the dynamic driver.

This design helps reduce acoustic interference between the two drivers, improving high-frequency clarity and overall sound coherence.

The result is more precise audio reproduction, allowing you to appreciate the finer details of your favourite recordings.
