A tribrid in-ear monitor combining a 10 mm dynamic driver, balanced-armature drivers and electrostatic drivers. It is designed as a refined, high-resolution monitor for audiophile and professional listening.

The HearWiki takeAI-condensed

This in-ear monitor uses a tri-hybrid driver setup, blending a 10 mm dynamic driver with balanced-armature and electrostatic units for a detailed, layered sound. Aimed at critical listeners, it delivers a polished, high-resolution performance that suits both audiophile enjoyment and studio-style monitoring. Its wired, 2-pin connection keeps things straightforward for those who already own quality cables and sources.

What works

  • Layered, high-resolution tuning across the frequency range
  • Tribrid driver design offers a cohesive blend of dynamics and detail
  • Comfortable fit with standard 2-pin connector for easy cable swapping
  • Good value for a flagship-level technical performance at this price

What doesn't

  • Requires a quality source and amplifier to shine fully
  • No noise isolation features, so external sounds can interfere
  • Bulky shell may not suit smaller ears
  • Wired-only design limits portability convenience

ThieAudio Monarch mkII REVIEW! Awesome, but be warned

Super* Review36.9K viewsSep 2022

The reviewer bought the Monarch MKII after being impressed by a demo, and finds it a significant improvement over the original Monarch, with a more balanced, mid-range-focused sound and excellent technicalities. However, he warns that the earpieces are very large and may not fit many ears, which can affect bass response and comfort, so he recommends trying them before buying.

Thieaudio Monarch MKII Review - Second Time's the Charm

The Headphone Show30.3K viewsJan 2022

The reviewer finds the Monarch MKII a solid improvement over the original, with exceptional mid-range detail and layering that punch above its price, but notes a less impressive bass and treble, a forward upper-midrange that can get harsh, and a metallic treble timbre. Despite these criticisms, he recommends it, though he still prefers the Symphonium Helios at this price.

Bad Guy Good Audio Reviews28.2K viewsNov 2021

The reviewer compares the Monarch MKII to the original Monarch and finds the MKII a clear improvement, especially in male vocals, which now sound more natural and authentic. The bass guitar and kick drum also show better definition and authority, though the reviewer notes it still may not satisfy bassists seeking self-monitoring. Overall, the MKII is seen as a well-executed refinement that splits the difference between the original Monarch and the Clairvoyance.

Monarch MKII - BETTER than the original?

The Headphone Show17.6K viewsApr 2022

The reviewer finds the Monarch MKII to be a solid IEM with excellent tonality, particularly in the mids, and good technical performance, but he struggles to recommend it at its $999 price point. He notes that while it improves on the original Monarch's tuning, the upgrade in resolution is minimal, and he suggests passing on it unless the price drops closer to the original's $730.

My thoughts on the THIEAUDIO Monarch MKII

TylersEclectic4.3K viewsJun 2022

The reviewer finds the Thieaudio Monarch MKII to be an excellent, warm-sounding IEM with strong bass, mids, and forward vocals, though the highs are slightly subdued and not very sparkly. It performs well for music across genres, but the reviewer did not enjoy it for gaming, finding the sound mucky in that context. Overall, it's a recommended purchase for those seeking a fun, easy-to-listen-to IEM, though the reviewer personally prefers their Mest MK I.
