In this video, I take a deep dive into the Meze Audio Astru, a new high-end in-ear monitor that challenges the limits of single dynamic driver performance. Crafted from pure titanium, the Astru brings a level of technicality and resolution that reminds me of much more expensive flagships. I’ll share my impressions of the soundstage, imaging, and that unique gold-sputtered diaphragm that sets it apart from the Meze Alba.

I also put the Astru to the test against the legendary Sennheiser IE600 and a mystery $1,000 multi-driver challenger to see if exotic materials truly equal better sound. Plus, I’m introducing my brand-new scoring system to give you a clearer look at how these stack up in terms of value, comfort, and timbre. Whether you’re a fan of the Chord Mojo 2 or the Hiby R6 Pro II, I’ll explain why your source gear matters more than ever with this specific tuning.
