Meze Audio ASTRU

The Meze Audio ASTRU is the brand's first in-ear monitor in the mid-to-high tier -- bringing Meze's signature warm, rich, and engaging sound signature into an IEM form factor, with a tribrid driver configuration combining a dynamic woofer, balanced armature drivers, and a planar tweeter in a precision-machined aluminum shell. Meze's first IEM to feature planar tweeter technology.

Type and Technology

Tribrid in-ear monitor. Driver configuration: 1x dynamic bass driver, 2x balanced armature mid drivers, 1x planar magnetic tweeter -- a combination that allows each driver type to operate in its optimal frequency range, with the planar tweeter delivering high-frequency extension and transient speed that balanced armatures and dynamic drivers cannot match at high frequencies. Precision-machined aluminum shell. Detachable cable with 2-pin connector. Available in multiple cable termination options. 3.5mm single-ended and 4.4mm balanced terminations available.

Sound Character

Rich, detailed, and spatially expansive -- the ASTRU applies Meze's signature warmth and tonal density to an IEM, while the planar tweeter extends the high-frequency performance beyond what a comparable all-dynamic or all-BA design achieves. The tribrid architecture produces a coherent, wide-bandwidth presentation that scales with source quality and amplifier pairing.

Build and Comfort

Precision-machined aluminum shell. Ergonomic nozzle geometry for secure long-session fit. Detachable 2-pin cable.

Best For

Audiophiles who love Meze's headphone sound and want it in an IEM -- and those looking for a tribrid IEM with planar tweeter technology at a mid-range price point.
