THIEAUDIO Valhalla Flagship IEM: Redefining Audio Excellence
The THIEAUDIO Valhalla sets a new benchmark for flagship in-ear monitors (IEMs), boasting an unparalleled 19-driver configuration per side. Featuring meticulously tuned Sonion and Knowles drivers, the Valhalla combines precision engineering and cutting-edge technology to deliver superior clarity, deep bass, and a refined tonal balance. Designed for audiophiles and professionals, this IEM ensures an unmatched listening experience.
Precision Bass System (PBS)
At the heart of the Valhalla lies THIEAUDIO’s proprietary Precision Bass System (PBS). Engineered to replicate subwoofer-level bass impact, the PBS uses a specially crafted resonance chamber and low-frequency filter cavity. This innovation achieves a precise 10dB bass shelf with sharp decay at 200Hz, extending bass frequencies to an ultra-low 5Hz-20Hz range. A pressure relief valve minimizes ear fatigue, combining impactful bass with long-lasting comfort.
Unrivaled 19-Driver Configuration
The Valhalla pushes the limits of audio technology with its industry-leading 19 drivers per side:
-
4 Sonion subwoofers for deep, controlled bass
-
10 Sonion low-midrange drivers for rich, warm mids
-
4 Knowles mid-treble drivers for sparkling highs
-
1 Knowles ultra-treble tweeter extending clarity up to 40kHz
This innovative design reduces driver workload, enhancing resolution, clarity, and tonal accuracy across the entire frequency range.
Advanced Acoustic Engineering
The Valhalla incorporates a sophisticated 4-way crossover system with a 4-bore acoustic tubing network, ensuring seamless transitions between frequencies. Unlike standard designs, it employs multiple 2nd-order networks for pinpoint precision, resulting in unrivaled audio clarity and balance. Impedance neutralization technology guarantees consistent performance regardless of the source.
Premium Grade 5 Titanium Housing
Crafted from aerospace-grade Grade 5 Titanium, the Valhalla offers exceptional durability without compromising comfort. Its ultra-lightweight, precision-CNC construction delivers a robust yet ergonomic fit, ensuring hours of fatigue-free listening.
Handcrafted Quality & Precision
Each Valhalla IEM is meticulously handcrafted by a single skilled engineer over an entire day. Components are individually measured, hand-paired, and subjected to rigorous quality control, including:
-
Post-assembly audio testing
-
Cosmetic inspections
-
Accessory verification
This commitment to craftsmanship ensures every unit meets the highest standards of quality and performance.

The Valhalla’s tuning reflects THIEAUDIO’s acclaimed signature sound:
-
Bass: Subwoofer-like impact with a 10dB shelf, decaying at 200Hz to prevent midrange bleed.
-
Midrange: Smooth 1dB slope from 200Hz-800Hz for natural warmth and balance.

The iem is designed aesthetically that it fits like custom made
Sound impressions :
Treble is perfectly done with being sibilant, Mids sounds very organic and clear, Bass is the best part here it's a step up from their previous flagship v16.
Staging is better and so is the resolution, A total flagship level iem which punches above the price tag
Thanks to Pritam for his exceptional customer service and deal .
Definitely recommended
I am a fan of listening audiophile music. Before I receive Valhalla, I am enjoying music with Shure SE846. Shure Se846 is a highly reviewed IEM. After I hear the audiophile music from Valhalla it is observed some thing special additions in the musical instruments which felt the musicians are performing live infront of me on the stage. The fit of the IEM shell in the ear snug and comfortable. Those who are audiophile listeners ready to spend good amount of money for iems can go for this.

Have a great features and I am very happy after buying this m71 thanks audio store 🙏🙏

Time Spent with this DAP is more than 50 days, used many IEMs from Budget range to high end.
OBSERVATION & EXPERIENCE SO FAR.
- Wide soundstage, it's creating a spacious listening experience.
- Smooth and refined sound, with good bass & trebles. I liked it.
- little high Volume doesn't hurt ears because of spaciousness which this DAP creates.
- Main unique point is Vocals & Instruments separation, it's best.
- So far, I noticed Battery back up is really good. Will check it over time and provide feedback.
- Does not get warm that too after using for hours.
- Best software & Shanling Music app, it's very fast ( I use 1TB fully loaded Micro SD card.)
Please Note - Little more care is needed while handling as it has Glass tubes. Again it's unique offering & tubes makes music more enjoyable.
CONS-
1. Charging time ( it will get solve by software updates in future, Brand has co
nfirmed it in their post)
2. Only one colour option is available from Brand.
3. Some settings currently not present, Brand may add in future updates ( DSD gain Compensation, PEQ, MSEB, Night light short cut in quick pannel)
CONCLUSION-
a. Highly recommend those who want detailed & immersive experience.
b. THREE IN ONE- One DAP but three modes, all three sounds differently. One mode Transistor (without Tubes) and two Tube modes (Triode & Ultra- linear).

Sterdy & beautiful cable. I am using it with Hidiz MP145 Planner Magnetic IEM. It add details to music over stock cable. Makes all aspect of sound quality better.

I am writing review after One month regularly uses with my two DAP - Shanling M8t, Hiby R4.
POSITIVES-
1. Best Soundstage
2. Balanced sound
3. Musical & Makes music more enjoyable to ears.
4. No fatigue despite of metal construct.
5. Weight distribution is really good.
6. Largest Magnetic planner in the Category.
7. Details & instruments separation at best.
CONS-
1. Small ears may face challenge. Plz contact team ATS before purchase. Normal ear size, No issues with fit & long usage.
2. Stock cable is good but doesn't suit this IEM.
I am using this with Divinus Auram cable, which goes really well with this by appearance as well as by performance.
CONCLUSION-
1. Very very happy with the purchase. It's my main IEM in daily music journey.
2. My suggestion is Music enthusiast must have atleast one 'Planner Magnetic IEM', believe me I found that the the songs which I am listening since decades are sounding differently with some more details with this IEM.

The KZ Castor is an excellent choice for budget audiophiles. It delivers superb sound quality that rivals much more expensive headphones, with clear highs, rich mids, and deep bass. The build quality is solid, offering both durability and comfort for long listening sessions. At its price, it’s a fantastic value, outperforming many premium options. Highly recommended!

i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.

Delivery was fast and item received was in good condition

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service
