Meze Audio has unveiled a new high-end pair of in-ear monitors aimed squarely at serious listeners.
Called the ASTRU, the new earphones promise flagship-level sound performance. However, they stick to a surprisingly simple design: just a single dynamic driver.
That approach is a bit unusual at this level. Many premium IEMs rely on multiple drivers to achieve greater detail and separation. However, Meze says the ASTRU is engineered to deliver similar layering and resolution using a single 10mm dynamic driver.
The secret lies in its unusual diaphragm design. The driver uses a multilayer composite structure with more than 80 ultra-thin layers of gold, applied through a 48-hour vacuum sputtering process.
Furthermore, that dome is bonded to a titanium layer and mounted on a PEEK base. This combination, Meze says, helps balance fast transient response with the warmth and physical punch dynamic drivers are known for. The result, at least on paper, should be a sound profile that’s detailed but still full-bodied.
The build quality is just as ambitious. Each ASTRU shell is CNC-machined from a single block of pure titanium, then finished with a multi-stage electroplating process to create a satin texture.
According to Meze, producing each matched pair takes up to seven days of precision processing. This is a sign the company is leaning heavily into its usual craftsmanship-focused design philosophy.
The earphones ship as a complete portable listening setup. In the box you’ll find a premium balanced cable with a 4.4mm termination, CNC-anodised aluminium hardware, and a 4.4mm-to-3.5mm adapter for broader device compatibility. Five ear tip sizes (XS to XL) are included. Additionally, there is a protective pouch and a soft PU leather carry envelope.
On the spec sheet, the ASTRU features a 10mm dynamic driver, a 5Hz–35kHz frequency range, 32-ohm impedance, and 111dB sensitivity. Total harmonic distortion is listed below 0.1% at 1kHz.
The ASTRU will make its public debut at CanJam New York on March 7. Afterwards, it will go on sale worldwide from March 20, 2026 via Meze’s website and selected retailers.
Pricing is set at £819 / $899 / €899, positioning the ASTRU firmly in the premium IEM space. Though it is still short of the four-figure prices many flagship earphones now command.
