The goal of Thieaudio was to serve as a creative platform for gathering the best teams of engineers to inspire revolutionary audio products for audiophiles and professionals alike. For each project, we hand select the most innovative and renown engineers in his or her field to oversee the design, engineering, and manufacturing of the products. We are proud to present two top-of-the-line signature series In-Ear Monitors - the Monarch and the Clairvoyance
Gathering the momentum from the success of the Thieaudio Phantom planar magnetic headphones, and the Voyager and Legacy series In-Ear Monitors (IEM’s), the two new monitors utilize the latest driver technology from the Danish manufacturer, Sonion - the Electrostatic (EST) tweeter. The EST driver features an ultralight membrane in a small tweeter chamber that is powered by an independent transformer to extend the in-ear monitor’s treble range up to 80kHz
From the tuning to the technical capabilities, the Monarch was designed to bring out the best that In-Ear Monitors can offer. The sound signature had to be analytical to bring about precision and a reference-style tuning. This necessitated a linear midrange section which would place all instruments balanced with one another and provide an overall clean and lean sound The mid-treble transition peaks at the inner ear canal resonance point and is sustained through the entire upper frequency range to maximize detail retrieval and overtone presence. Yet, careful attention was placed in making the trebles smooth and void of sharp peaks or dips to eliminate any uncomfortable upper harmonic irregularities. We find the Monarch to be among the few IEM’s on the market to truly and cohesively integrate the balanced armature and EST drivers in a manner that shines forth the best of their potentials The Monarch stands as Thieaudio’s best display of technological and sonic innovation and is ready to redefine the musical standard for In-Ear Monitors. On the other end of the spectrum, a 10mm dynamic driver and multi-balanced armature woofers have been implemented to bring about a punchy subbass impact. The lowpass point was selected below 150Hz to create an even cleaner midrange section, while still allowing a powerful subbass to lay down the foundation y
Thieaudio was launched in 2019 as a creative endeavor of Linsoul Audio. We are committed to the continual expansion on the limits of high-fidelity audio. We welcome you to join us and experience excellence in musical performance! In reality, the utilization of this driver configurations effectively enhances the extreme-treble response and thereby provides a protracted treble decay, a more airy atmosphere, and enhanced sound resolution. The correct implementation of EST drivers can make normal balanced armature driver earphones seem dull and lackluster in comparison. Pairing the EST driver with a newly developed biopolymer dynamic driver and traditional balanced armatures, we have styled two unique IEM’s. The Monarch focuses on a precise treble response with extreme detail retrieval and high level of clarity. It is an exceptional candidate for a CIEM (Custom In-Ear Monitor) fit due to its characteristic sound signature. The Clairvoyance emphasizes a natural tonality with a powerful subbass and a smoother treble section. A re-envisioning of the popular Harman curve, the Clairvoyance emphasizes a clean sound with an impactful subbass and extended high frequencies. Both models are ideal for any circumstance in which uncompromising tonality and technicality are needed, and we could not be prouder to present the pinnacle of Thieaudio’s engineerin

If you are considering purchasing, DO IT! My simple sincere recommendation.
ThieAudio Monarch are absolutely amazing delivering amazing sound including my DSD256 albums from my AK Kann Cube in absolute perfection!!
Don't get them as CIEM, thieaudio is lacking the expertise to make CIEM. The nozzle was too short and not sealing properly. After waiting for months, they couldn't make them.
If you want those, get the universal.
Considering all the components within the monarch it is lacking in any substantial bass response. The mids and highs are ok but due to the obviously missing bottom end I will probably never listen to music with these. While waiting for these customs to be built I was using a pair of inexpensive KZ ZSX and the difference is so outstanding I will use the KZ's from now on. I recently acquired an ASTELL&KERN SP2000 and the monarchs were a major let down. It's difficult to sell custom IEM's.
Ordered them back in January, then a huge surge of orders + CNY got a projected delay till mid-April. Then I was super surprised they actually shipped them mid-March, and they literally arrived in 2 days despite me being in another continent. The box is one of the simplest I've ever seen, just the IEMs, a few eartips, a cable, and a leather case. That's how you know they got nothing to overcompensate for, the sound from these beasts is unbelievable. Here is my Pros/Cons list.
- Soundstage widest I've seen on IEMs. You close your eyes on some songs designed for holographic testing and you just forget you're sitting on your couch at home.
- Sibilance, imaging, resolution, etc are just... phenomenal
- Instrument separation and detail is so high that it's honestly almost overwhelming (very hard to use those for background listening, it's like going to a concert and playing on your phone, you can't not focus on it)
- Subbass is impossible to describe. I didn't even think it's possible to have something so tiny almost give me a good concussion from a subbass-heavy song.
- Highs are probably clearer than my own ear can interpret. You know how 4K TV looks crisper than reality? Yeah that's the Monarchs when it comes to highs. Quite rare to find a company that uses electrostatic drivers and actually knows how to tune and implement them.
- The universal faceplate is super beautiful (picture doesn't do it justice), cable is so bright, shiny and durable, and the case is super elegant, large enough to fit them, but small enough to be very portable (and it smells like genuine leather! although I don't know if it's actually that).
- The IEM body fits quite snuggly into the ear, and the general design is very smooth (spatially and stylistically)!
- EDM sounds stunning on these, and honestly everything else sounds excellent (I tried alllllllllllllllll sorts of metal subgenres, plenty of rock, and a few classical pieces plus a bunch of test tracks).
- The IEMs are definitely not suited for those with small ears (or even medium ears). They're quite large, which means they fit quite tightly, but might cause some ear pain after some hours for those with average ears.
- The mid-range is extreeeemely neutral. This is a huge plus for those who seek it, but for me, I think I'd have preferred the dip from the subbass to the mids to be a little later such that the mid and high bass ranges are stronger. I think it gives the music a little more body, but perhaps they did this on purpose because when I equalize to raise the mid and high bass by a bit, it actually gets very overwhelming when combined with such a powerful subbass response.
- I'm super happy they added the nozzle lip, but.. I feel like they forgot to consider that now all the eartips provided are super tight on the nozzle. I felt like I was going to rip the tips off when I took them off.
- Although I very much love the cable, I would have personally preferred a 90 degree bend instead of a straight plug. It's just easier to sit with my phone in my pocket without fearing I'll break the plug.
Suggestions to ThieAudio:
- Perhaps you should consider writing "Monarch" in addition to "ThieAudio" on the faceplate, or even on the inside. To distinguish them from the Clairvoyance without having to look at the contours and faceplate tiny differences.
- It would be nice if you add some more ear tips. Nothing fancy, just other sizes of spinfits.
- The little bulge at the top of the IEMs, next to the vent, is a little too bulgy and kind of presses on the ear anthelix. Would be awesome if you reduce it.
- I think it would be nice if you adjust the 2pin connection so that there is no gap at all between the cable and the IEM, to prevent dirt issues in the long-term.
Conclusion: I know I listed many cons, but it's just because..... these are the best IEMs I have ever heard by FAR, and I want them to be perfect (I'm hoping my opinion is heard by ThieAudio, I know they already took in consideration some customer feedback before). It almost like they hired the best audio engineer in the world to incorporate and tune the drivers in these IEMs, but they only hired the second best physical product designer (shell, cable, etc.). Do I regret buying these? No way, best purchase of the decade. The Monarch easily competes with IEMs currently sold for over 2k bucks. Also, thank you Linsoul for the awesome customer service! You made an audiophile very very happy.
Utterly outstanding headphones.
I have a pair of Noble Kaiser K10s and the Monarchs absolutely kill them.
Highly, highly, recommended.
Loved this set, check out my video review here: https://youtu.be/Y7Y02X5XOeU
Very fun sounding sub bass. Bass in general lacks a bit of punch + no texture to bass at all, but still addictive fun iem for electronic music. my only gripe is that's it's simply a disgrace that for 700$+ of one's hard earned money they manufacture iems with no recessed sockets! that's simply unacceptable. You can see a fraction of a millimeter of bare pin contact. very disappointing design decision. Own a pair of fearless s8p for example - the sockets there are much more secure.
Excellent clarity across the board. The sound signature is a bit like a mix between an HD650 and HD800. All the clarity you want with a very natural tone. The slight issues I have with the tuning are the slightly too boomy sounding sub bass and there is some kind of peak (probably 8K) that adds a bit of spice to the treble but it's not bothersome for someone who is fairly treble sensitive.
Absolutely mind-blowing sound. Would recommend as #1 IEMS sub $1000. Changed out cables to Linsoul Nymph, so I don’t have to use the bulky adapters.
