REVIEW AFTER ONE MONTH DAILY USE
Initially, my set up was 'Samsung S 23 ultra + Simgot ew 300 DSP' for daily music listening hobby.
While upgrading from this set up, 1st I bought HIBy R4 DAP, used it for 10 days with same IEM and then decided to go for another big upgrade for iem. After trying existing iem on multiple phones, surprisingly I observed that 'Hiby R4 DAP' is superior even on high-end phones in terms of sound quality.
While upgrading IEM, I kept below criteria and told Mr. Pritam the same.
1. IEM with crystal clear sound with all details & balanced sound.
2. Ultra wide Soundstage & clear imaging
3. Clear stereo effect
4. It should separate Instruments sounds when there are multiple instruments in song/music.
5. It should handle bass heavy songs without compromising vocals & trebles.
6. Comfortable for long hours.
Now after using it more for one month, I can say that -THIS IEM HAS FULLFIELD EACH REQUIREMENT & ASPECT OF SOUND QUALITY.
Only downside I felt that Packaging and Case should be premium in this price tag.
EXPERIENCE WITH AUDIO STORE -
I had some options for IEM in my mind based on previous listening sessions at audio store office as well as youtube & web reviews.
I recently visited audio store office two times for some other product requirement, All those previous options, I tested all of them again. I found that Mr. Pritam's suggestion to buy MK3 over other IEMs is worthy.
Thanks a million Mr. Pritam for always helping & guiding before taking any major purchase.
Yet to burn out ; on slight use its very good on treble & music seperation and bass also good but not top notch, i’m using it with hyby r6 proii which has lot of equalizer setting still exploring best sound settings as per harman curve.As of now it sounds very good as i upgraded from final e5000 and will update the review further after some days of listening.
Thank you for sharing your thoughts on the ThieAudio Monarch MKIII IEM. We appreciate your feedback on the treble, music separation, and bass. We're glad to hear that you have upgraded from the final e5000. We hope you continue to enjoy your new IEM and we look forward to any updates on your listening experience. Happy listening!

Our team takes great pride in providing a product that delivers impeccable performance and clinical precision across the entire frequency spectrum.

These are good and, I can listen to them for days even at 40% volume through a KA3 or KA5 Fiio dac no problem, I generally listen my music at 2% to 8% volume on other iems as they start hurting me after 2 or 3 songs but these are so smooth. Also with these I can hear my music at 2% volume but after 40% volume they come alive and the full potential is opened up so in the beginning I did not find any difference with these as I was listening to my usual 2% volume but once I thought let's try one song at higher volume and Bingo. Also my ears are big so these fit perfectly like a glove and passive noise restriction happens. All my Iems I have re tuned to sound good so they all sound great but I can only enjoy those while in front of my pc because I can't carry my tuning with me but these I tried to tune and soooo little tuning is required I was amazed so now I can carry a almost perfectly tuned iem along with me 😃 that's nuts. Also I have an unboxing video of it on YouTube link is below enjoy👍🏻🙏🏻

Best Budget IEMS. This was my first time buying this iems and i didnt got single complaint for this. its just good for this price point
New on this IEM journey and I must say they sound better than my 3x priced headphones.
I like the sound and clarity.
Coming from Juzear Defiant and Punch Audio martilo, I would say that this is the best I have till date. Excellent in terms of clarity and technicalities. Being a medium sized IEM it is very comfortable for long listening sessions. Kudos to TAS for their excellent service.
I visited the experience store at Pune and Pritham and his asistant were very warm and welcoming. They patiently explained the pro's and con's of the Hidizs and gave me alternatives to try like the Truthear Nova and Simgot Supermix. Experiencing the different IEMS helped me maake a solid choice of what I wanted.
Also took time to sample an open back Sennheiser HD660S and the Hifiman Sundara. Was able to clearly make out the differnce betweeen a planar magnetic and DD. That helped me know what my prefernces were. Truly enlightening experience ended with a great purchase in the HIDIZS MP145.
These are my first IEMs. After a bit of research, I decided to go with the KZ Castor Pro as my first IEM. I'm really impressed with the audio depth, the crispness of audio and the clarity and separation of instruments and vocals. The music feels much different than the usual TWS earbuds which I was using before! The packaging was good, and delivery from Audio Store was good! Glad to have officially entered the IEM clan!
The Audiocular Spark DAC is amazing and it really enhances the audio quality compared to using my IEMs directly on my PC. The build is excellent, durable and it also comes with a carrying case. The packaging and delivery were both good. Really glad I bought this from here!
Unbelievable this TANCHJIM Bunny Type-C DSP whenIwas unboxed and listen immediately lheard totally theatricale experienced.It'stotally mesmerized me in sounds. In this price unbelievable soundquality. That's why this TANCHJIM Bunny Type-C DSP is more value than itsprice. Thanks once again to Pritam ji for suggestingme so wonderful IEM.
I herd of them and brought them was concerned but the audiostore team was gental and the quality of product was superior
Sound quality is very very neat and clean and in depth. Best purchase ever.
It's an amazingproductforthe price
I purchased these during christmas- and my initial impressions were that these were packaged well, and felt very premium in hand, except for the cable.
The bazz is very lacking, and the iems are unusable without tuning. After tuning these sound full, and have beautiful clarity. Definitely recommend if you can tune them. Also very good for video editors and others who need stock audio
It sounds wonderful 👍
I am very satisfied with my purchase and currently enjoying hi-res audio with my iem. Best looking and build quality is also good under 1K
This is my first IEM. I like the way it sounds. Though I expected much better soundstage but it is good. After using this, I will definitely buy my second IEM. Trust The Audio Store, they delivered as expected. Actually someone suggested me on reddit to go with audio store and I will definitely recommend others the same.
Just got some time with these and here's my honest take:
Comfort: These things are stupid comfortable. Lightweight shells that disappear in your ears, zero fatigue even after long sessions. Stock tips are meh though—nothing special, you'll probably want to tip-roll.
Sound:
- Vocals are pushed forward and warm with less sparkle/energy up top. Great for that intimate, smooth vocal presentation but not if you want bright, analytical vocals
- Bass is elevated and textured but definitely not basshead levels. Hip-hop/EDM heads will find it lacking
- Treble rolls off early = excellent sibilance control. Zero harshness or fatigue, perfect if you're treble-sensitive
Who's this for? Warm vocal lovers and anyone tired of harsh, sibilant treble. Long listening session champs.
Who should skip? Bassheads, treble sparkle chasers, people wanting analytical/reference sound.
For the price, these carve out a nice niche—they're not trying to do everything, just warm and smooth really well. Worth it if that's your vibe.
