Meze ASTRU 10mm Driver (1DD) In-Ear Earphone
- Visceral, full-bodied, rich-sounding audio
- High-performance 10 mm single dynamic driver with the resolution of a multi-driver configuration
- Multilayer composite dome: 80 ultra-thin gold layers + titanium coating over a PEEK membrane
- CNC-machined titanium chassis, precision-engineered for long-term comfort
- Electroplated nickel wax guard
The Meze Audio ASTRU's design is understated, leaving all of the glory to its performance and sound quality. Historically, IEMs have been regarded for their eye-catching designs with flashy faceplates. Over the last couple of years, I've noticed a shift in the IEM market. We're moving away from big bling and toward understated minimalism, where design is only part of the equation. Meze Audio has always approached their IEMs with this mindset, and the ASTRU is a clear example of that.
The ASTRU doesn't feature any huge logos, colorful faceplates, or wacky designs. It builds on the ergonomic foundation of previous Meze Audio designs–the ALBA and ADVAR–and refines it for improved long-term comfort. It's got a titanium body, a grooved shape that mimics the natural ear, and a single small logo on each IEM that's out of sight when you're wearing them. Each IEM shell is CNC machined from a single block of pure titanium, then refined through a multi-stage electroplating process that applies an electroplated nickel wax guard for built-in protection and a smooth satin finish.
The ASTRU's design is indicative of Meze Audio's commitment to comfort and craftsmanship. Rather than producing as many units as easily as possible, they've chosen a process that takes up to seven days per pair to complete. And what you get is a precise fit with a lightweight feel and long-term durability that doesn't compromise sound transparency.
If you've read any of my IEM reviews before, you know I've historically struggled with fit and comfort. I have small ear canals, so what fits most usually doesn't work for me. The overall shape of an IEM greatly contributes to this; the larger the housing is, the harder it is to achieve a tight seal. I've auditioned IEMs of all shapes and sizes and shuffled through many types of ear tips, so at this point, I've got it down to a science. While a pair of custom-fit IEMs solves any qualms you might have, the ASTRUs are strictly offered as universal-fit IEMs.
Growing up, my younger brother was a very picky eater, so any time we ordered fast food, all his sandwiches had to be plain. After many years of this, my dad swore he could tell if the sandwich was plain based on the weight of the bag alone. I used to think he was crazy; how could you tell without examining the product? Well, in the same way my dad could judge a sandwich by weight, I can judge an IEM's fit on looks alone. As with anything, there's room for error, and I don't always get it right, but in the case of the ASTRU, I could tell these earphones would fit me perfectly as soon as I opened the box.

Due to recent changes in U.S. trade regulations, additional tariffs are being imposed on products manufactured in China and imported into the United States. As many of our audio products are made in China, orders shipped to U.S. addresses may be subject to an added tariff charge at checkout, reflected as a "U.S. Import Tariff Surcharge". Please note that this surcharge amount is determined by U.S. import policies and may vary significantly depending on product categories and any future policy adjustments. These charges are necessary to ensure compliance with U.S. customs requirements and to allow us to continue serving our U.S. customers reliably. We strongly encourage you to review the total cost at checkout before placing your order.
This surcharge is temporary but necessary during this period of significantly increased operational pressure as a result of the ongoing geo‑political situation in the Middle East.
Orders shipped to Gulf Cooperation Council (GCC), Africa, US and EU regions may be subject to an added surcharge at checkout, reflected as a "Temporary Emergency Situational Surcharge". Please note that this surcharge amount is determined by our freight partners, and may subject to adjustments according to situational updates.
