Enjoy Crystal Clear Bass with IMPACT2 Tech inside the Monarch Mark 3

The MKIII features not one - but two 10mm composite diaphragm drivers in an isobaric design.

The additional driver enhances the texture of the bass, while keeping pressure and frequency consistent.

This allows for you to enjoy quality bass without giving up overall integrity.

Close your eyes and feel the bass throughout your body.

Monarch MK3 Frequency Response

THIEAUDIO's engineers have retuned the Monarch MKIII for a balanced, studio-neutral sound with a slightly warmer low end.

The legendary sub-bass impact remains, but has been tamed for a more natural bass presentation that doesn't muddy the mids.

Additionally, the Ultra-Treble range has been expanded - allowing for greater staging, atmosphere, and enhancement in resolution.

This means you'll be able to hear your music in greater detail than ever before, while still retaining the impactful sub-bass and bass of the Monarch MKII.

Feel And Hear The Texture with the Monarch MK3 In-Ear Monitors

THIEAUDIO has improved the physical texture of the cable by using a soft braided paracord material.

Additional strands also provide a slightly meatier feel and a richer sound, so that you can both feel the texture with your hands and hear increased texture in the sound.

Admire Supreme Craftsmanship with the Monarch MKIII In-Ear Headphones

The Monarch MKIII features an ergonomic and lightweight design, allowing for hours of listening pleasure.

The precision engineered medical-grade housings allow for ultimate comfort and premium styling.

This means that you can enjoy audiophile-grade performance while on-the-go.

Rid Your Tunes of Distortion with the Monarch MK3

Consisting of a true 4-way crossover with 9 passive components, the Monarch MKIII maintains ruler-flat neutrality in the mids while still allowing for punchier sub-bass.

A new tuning strategy also revamps the mids, separating driver ranges to maximize output, while minimizing harmonic distortion.

These features together make for a higher resolution sound and retain studio-monitor quality, so that you can hear your tunes clearly.

Connect the Monarch MKIII To Your Audio Source with SMARTSWITCH Tech

The Monarch MKIII comes equipped with THIEAUDIO's new Smart SwitchTM cable system, so that you can connect to any audio source.

This modular design allows you to easily switch between 2.5mm balanced, 3.5mm unbalanced and 4.4mm balanced connections for seamless pairing.

THIEAUDIO Monarch MKII vs MKIII

This product is the update to the THIEAUDIO Monarch MKII. If your ears are more sensitive to treble or would like higher levels of bass/sub-bass, check out the MKII here.

Bass:

Prominent mid-bass in the MKIII creates impactful and full bass signature overall, while the MKII can have a slightly cleaner bass and mid-bass sound due to its leaner tuning.

Mids:

The Monarch MKIII is more full and bodied in the mids, allowing for excellent resolution - separating male and female vocals more effectively than the MKII.

Treble:

The higher levels of treble in the MKIII can bring more detail to the table, while the MKII is more reserved in this aspect.

Detail:

The MKIII has a slightly better resolution due to the improved mid-range tuning, making your music clearer than ever.

Package Contents:

The MKII and MKIII contain the same items upon shipping.

THIEAUDIO Monarch MKIII vs Prestige LTD

Choosing between THIEAUDIO's top IEMs is tough. If you enjoy more acoustic tunes or natural notes, check out the Prestige LTD here.

Benefits of the Monarch MKIII:

Harder hitting bass, more fun/unique sound, and higher levels of treble.

Benefits of the Prestige LTD:

Reference-style bass tuning with impact, tighter tuning, less treble, and smoother sound overall.
