Precision 4 Balanced Armature Drivers

Each side features four balanced armature drivers, two handling the low range and one each for mid and high ranges.

Eight drivers deliver robust bass and delicate treble tones.

What is a Balanced Armature?

A Balanced Armature unit used in premium earphones employs a metal-based ultra-thin diaphragm that directly receiver vibrations from the armature and metal drive pin to produce Hi-Fi sounds.

This high-end driver unit delivers clear and flat sounds and is ideal for noise isolation and treble reproduction. Even the most subtle sounds are clearly produced thanks to the lack of coil-produced vibrations.

High, Mid & Low Crossover

A sophisticated crossover separates sound signals into three frequency ranges to faithfully reproduce sound through four balanced armature drivers.

The 3-way crossover deliver a harmonious and perfectly-balanced sound, from the deepest bass to the clearest highs.
