01 Custom LCP+PU dynamic driver

The composite diaphragm balances stiffness and damping to produce low-frequency impact with controlled decay.

02 Four balanced armatures

Dedicated BA drivers add midrange articulation and refined treble detail above the dynamic bass foundation.

03 Hybrid crossover

Electrical and physical acoustic filtering coordinate the five drivers and reduce unwanted overlap.

04 Resin shell

A lightweight resin body is paired with a CNC metal faceplate for comfort and a more premium finish.

Airoso is tuned as a warm, engaging hybrid, using dynamic-driver body below and balanced-armature clarity through the mids and highs.
