A quadbrid flagship IEM with a dual-sided bone conduction driver alongside dynamic, balanced armature, and electrostatic drivers.
Official product pageOverview
The MEST MKII uses an 8-driver-per-side quadbrid configuration: one dynamic driver for bass, four balanced armatures for mids/treble, two electrostatic drivers for ultra-high frequencies, and a dual-sided piezoelectric bone conduction driver positioned between supporting plates for full-range refinement. The single-piece carbon fiber shell has gold foil accents on the ear cavities, and the included cable is 4-core 24AWG OCC copper with selectable 2.5mm/3.5mm/4.4mm terminations.
Pros
- Quadbrid 8-driver-per-side configuration: 1DD+4BA+2EST plus a dual-sided bone conduction driver
- Single-piece carbon fiber shell with gold foil accents
- 5-way crossover for driver integration
- Includes AZLA SednaEarfit Xelastec eartips in the box
Cons
- $1,499 is the most expensive product in this batch by a wide margin
- Bone conduction driver technology is a newer, less-established approach than pure BA/EST designs
- 12.3Ω impedance is unusually low, meaning source noise floor matters more than usual
