Monarch, Pushing beyond the Pinnacle

At their times, the original Monarch and the Monarch MKII set new standards for best-in-class performance in the global IEM industry. Not only did it redefine the price-to-performance bracket, but it forever changed how IEM manufacturers engineer and tune IEM’s. Keeping with the times, the Monarch has undergone another revision to revamp its technical and tonal performance.

Enhanced Ultra-Treble Output

The Monarch MKIII has been updated with Sonion’s latest electrostatic (EST) drivers and re-tuned to better exhibit these drivers’ full potentials. Thanks to our new tuning strategy, the ultra-treble frequencies at +15kHz to 20kHz have been increased for a more comprehensive upper frequency extension. Compared to its predecessor, the Monarch MKIII will have a greater sense of staging, atmosphere, and an overall enhancement in perceived resolution thanks to the treble extension. 

Balanced Tonal Signature

At the core of the Monarch MKIII is THIEAUDIO’s commitment to tonal excellence. The Monarch MKIII retains a studio-monitor like tonal signature with a focused sub-bass impact for a clean, natural, and detailed sound. Engineered with a true 4-way crossover with 9 separate passive components, the Monarch MKIII stays true to its tonal legacy. Thanks to IMPACT2 , the subbass is punchier, but the mids from 200Hz to 800Hz retain their ruler-flat neutrality. This tonality of the mids mimics the true sound of studio monitors used in recording studios to deliver accurate audio reproduction.

Furthermore, compared to its predecessors, the Monarch MKIII mids have been revamped with a new tuning strategy, which better separates respective driver ranges to maximize output while minimizing the total harmonic distortion. This means the mids on the MKIII will sound higher in resolution while retaining the same monitor-esque tonality. The treble has also been slightly re-tuned to offer more coherency throughout the region, as well as little more clarity and definition. This slight tonal modification better mixes with the renewed ultra-treble response, providing a more crisp sound signature.

unbelievable

these are my first pair of iems since i started in the audio scene. i can’t even believe how they sound. the imaging, depth, texture, soundstage, separation… its perfect. paired with a neutral source, the sound is balanced but really full and with a lot of body. it’s really impressive what this iems can achieve. absolutely recommend them

My first and last IEM. 🐐

I have done my research and also with the help of chatGPT to have a broader understanding of the audiophile world. You need a dac, and an iem? Get this. I listen to ALL THE HIT songs of drake, kendrick, j. Cole, pac, biggie, Jay-Z, Eminem, NWA, Ne-Yo, Usher, Chris Brown, Outkast, Michael Jackson, Eagles, Journey, Air supply, Bryan Adams, Whitney Houston, Celine Dion, Guns&Roses, Metallica, Led zeppelin, Linkinpark, Redhot, ac/dc, paramore, my chem, greenday, kiss, and all the popular EDM from david guetta, zeds, daft punk, kygo, avicii, illenium, marshmello, thefatrat. I have a very broad playlist bro. They all sound amazing!! 🤩🤩🤩🤩

If you listen to any of the mentioned artists above, or maybe if you could relate to some genre? Then they all sound amazing using the monarch mk3. I’m currently using a hip dac 3 that has a burr-brown chip, and idk how to differentiate a tube amp, solidstate burson dac, or any feliks-audio dac/amp. Thats why I just decided to buy a hip dac 3 instead. But I’m soon to be upgrading to an ifi gryphon for my dac and buy a meze empyrian 2 for my endgame headset. Im sick and tired of chasing the new bluetooth headset or earbuds that cant even listen to a 💿 44.1khz CD - Quality 🤦🏻‍♂️ what more for buying a $400 sony/bose earbuds that cant listen to 96khz Hi-res? I feel like its a waste of money and people are missing out. You coulda bought a moondrop or a hype 4 with that $400. I lost the case tho and the 2.5mm jack and 3.5mm jack within a week. It would be nice if they sell the case on the website or maybe get me a free one since this is a pretty good glaze and shill 😂 but overall bro, this is a solid 9.5/10🔥

Great Headphones

I love everything about how they sound. Sounds amazing with music and gives perfect footsteps positions in games like sonar(I know that's probably not the intended use but its the best at it I've heard from my headphone collection). My only complaint is that occasionally the glue will wear out and you will have to glue the seam back together, which is easy but annoying(especially if you let it come all the way off as it may rattle if you don't put it back together perfectly). I know the plastic is the lightest option and these are very comfortable and durable but I wouldn't mind having a aluminum case with screws as an option.

Not seeing 1500$

Idk, I just don't see 1000$ of value here. As some people say on forums, single driver is more coherent then any multi driver, and I have to agree. Coherency is important for imaging accuracy, and I can't justify going multi driver for like a small barely tangible increase in details.

Are these good? Yeah sure. But I could see this as more of a 300$ iem then 1000$. Kiwi Ears is close to eating this market even with their Quartet.

End Games?

I've been into this for a long time and own various high-end headphones. But Monarch MK3 managed to surprise me! Finally a WOW effect. Excellent tonal balance, very natural and detailed sound. Really looks like end games
