About the Apevoix Grit
From the product page on linsoul.com.
The Apevoix is a tribrid IEM featuring three independent types of drivers. A 10mm dynamic driver (DD) powers the bass, 4 balanced armature drivers (BA) delivers the mids and treble, while an all new bone conduction (BC) driver presents incredible texture to your music. A total of 6 drivers in a 4-way crossover network ensures your music is accurate, detailed, and rich.
The Apevoix features a powerful new bone conduction driver that delivers an incredibly realistic sound. Using a 11mm latest generation of bone conduction driver, the Apevoix presents an entirely new listening experience by using contact-vibrations, rather than traditional acoustic tubes, to produce sound. The bone conductor targets the entire frequency range, with strong rumble in the bass and pristine texture in the trebles to enhance your music.
