IEM Description
The Monarch MKIV is the latest evolution in Thieaudio’s Signature Series, now featuring a tuning switch that lets users toggle between two distinct sound profiles: STANDARD mode offers a studio-neutral tuning with clean mids and refined treble. RUMBLE mode adds +3dB sub-bass for a warmer, more powerful low-end response. It sports a lightweight T6 aluminum shell, an advanced 4-way crossover system with 9 passive components, and the upgraded IMPACT2 isobaric dual-subwoofer setup for tight, impactful bass. Treble is handled with precision thanks to improved EST driver integration for smoother and more extended highs. The MKIV also introduces the new Chocolate modular cable system, offering both 4.4mm balanced and 3.5mm unbalanced terminations with silver-plated OFC wires. A versatile flagship IEM combining technical excellence with customizable tuning.
The driver configuration is Tribrid. It consists of 2 Dynamic Driver, 6 Balanced Armature & 2 Electrostatic. This IEM was released around June 2025.
