Introducing IMPACT2 (Impact Squared), the latest technological breakthrough from ThieAudio, revolutionising the personalised audio industry. IMPACT2 is a cutting-edge subwoofer solution featuring (x2) 10mm composite diaphragm drivers arranged in an isobaric design. By adding another 10mm subwoofer, the bass's power and texture are significantly enhanced, while the in-house isobaric chamber design ensures consistent frequency and pressure. As a result, you can enjoy superior bass quality without compromising on tonal integrity. IMPACT2's dual 10mm subwoofers deliver a truly immersive audio experience with enhanced bass that takes your listening pleasure to a whole new level.



The Monarch MKIII has undergone significant updates, now featuring Sonion's latest electrostatic (EST) drivers, and benefiting from ThieAudio's advanced tuning strategy.

With these improvements, the Monarch MKIII delivers a heightened sense of staging, atmosphere, and overall resolution, elevating your listening experience to new heights. Additionally, the MKIII's mids have been carefully refined to enhance the separation between individual driver ranges, maximising their output while minimising Total Harmonic Distortion (THD).



At the heart of the Monarch MKIII lies ThieAudio's unwavering dedication to achieving exceptional tonal quality. The MKIII maintains its studio-monitor-like tonal signature, ensuring a clean, natural, and highly detailed sound with a focused sub-bass impact. Retaining its tonal legacy, the MKIII incorporates a genuine 4-way crossover with 9 separate passive components, upholding its commitment to tonal excellence. The IMPACT2 technology further enhances the sub-bass, delivering punchier results, while the mids from 200Hz to 800Hz remain neutrally flat. This characteristic tonality in the mids closely mirrors the precise audio reproduction of studio monitors used in professional recording environments.

An outstanding IEM

Though i didnt buy the Monarch MK3 on headphonezone i feel i have to write this review. It really is fantastic and once you start listening on it you will not want to listen on your other IEMs for a while. The clarity,detail,bass and treble extension are spot on. Songs feel presented on wide soundstage and are presented beautifully. Great value for money. My endgame IEM.

Thanks for the great review! We're glad you love the ThieAudio Monarch MKIII!
