Description
ThieAudio HYPE 4 MKII redefines what a mid-range hybrid IEM can achieve, delivering exceptional audio engineering and a completely redesigned architecture for superior performance. Built from the ground up, the HYPE 4 MKII introduces upgraded Knowles balanced armature drivers, a Gen 2 IMPACT2 sub-woofer system, and a precise 4-way crossover network, resulting in outstanding clarity, power, and musical realism.
Unmatched Bass Performance With Gen 2 IMPACT2 Sub-woofer
Equipped with two 8mm composite diaphragm dynamic drivers enclosed in ThieAudio’s proprietary pneumatic chamber, the HYPE 4 MKII produces thunderous, ultra-focused sub-bass without affecting midrange accuracy. The IMPACT2 system delivers deep rumble and fast decay, ensuring tight bass separation ideal for modern genres, stage monitoring, and immersive listening.
Upgraded Knowles Balanced Armature Drivers for Superior Detail
Featuring a complete overhaul in driver configuration, the HYPE 4 MKII uses imported American Knowles BA drivers for enhanced tonal accuracy. Dual RAB units deliver rich and textured low-mids, while the ED-33465 driver presents articulate upper mids and natural vocal presence. A Knowles RAD-33518 ultra-tweeter, positioned directly in the nozzle, extends treble air and sparkle with electrostatic-like transparency—perfect for precise imaging and expansive soundstage.
Refined Tuning for a Studio-Neutral Yet Musical Signature
The tuning philosophy strikes a perfect balance between professional reference neutrality and musical enjoyment. With a 9dB sub-bass boost that cleanly rolls off at 150Hz and a warm 400Hz midrange emphasis, the HYPE 4 MKII remains natural, clean, and engaging. Treble features controlled decay for exceptional texture and detail without harshness or fatigue, making long listening sessions effortless.
Premium Build Quality & Hand-Crafted Precision
Constructed from CNC-machined solid aluminum blocks, hand-finished, and anodized for durability, every unit undergoes multiple inspection phases to ensure perfect driver matching and long-term reliability. Internally, a 4-way crossover and 4-tube acoustic system with 7 passive components achieves unmatched coherence and technical performance.
High-End Modular Cable Included
The premium cable uses 7N ultra-OFC copper and silver-litz wiring for maximum signal integrity, paired with a modular plug system supporting 4.4mm balanced and 3.5mm unbalanced connectors for maximum source compatibility.

"Unbeatable planar clarity, smooth treble, and deeply immersive soundstage at this price point!"
I recently purchased the Letshuoer S12 Ultra from The Audio Store, and pairing it with my Samsung S24 Ultra, FIIO BTR17 (via 4.4mm Balanced), and Apple Music Hi-Res Lossless has been nothing short of extraordinary. It delivers a truly world-class listening experience!
Key Highlights:
Planar Technicalities & Imaging: The 14.8mm Planar driver offers lightning-fast transients, laser-sharp instrument separation, and a surprisingly wide, holographic soundstage.
Smooth & Energetic Tuning: Compared to earlier S12 iterations, the Ultra brings a much smoother upper-mid/treble presentation with zero sibilance, while retaining authoritative, deep sub-bass rumble.
Synergy with BTR17: The dual ES9069Q DAC and clean THX amplification from the FIIO BTR17 give the S12 Ultra all the juice it needs to shine.
Build & Accessories: Excellent CNC aluminum shells, ultra-comfortable ergonomics, and a modular 3.5mm/4.4mm silver-plated cable right out of the box.
Verdict:
If you want an endgame-level portable audio setup without breaking the bank, look no further. Kudos to The Audio Store for the lightning-fast delivery and top-notch packaging! 🎧 absolute recommended!
The DAC works like a charm. Works with various devices. Recommended even if it does not come with PEQ. Try Equalizers of your choice to tune the sound as per your taste. I have paired it Duonic (improved bass version)
Just received my order and these little thing is fabulous. Like it just increased my iems potential. Solid quality and looks premium. Easy to carry comes with a fabulous quality case which you can use to store your iems too. Moreover there was really a difference without it and with it in sound and overall. So go for it without any hesitation ✌️
The audio quality is amazing. The noise barely escapes to outside. Overall a great purchase worth the price
I was impressed by fast and well managed delivery 📦 . Coming to moondrop space travel 2 ultra..one word awesome..I was searching for tws loud enough and quality sound and I am fully amazed by sound.
Very best audio quality each and every vocal was crisp and clear in future I will buy more Iem from audio store❤️
After using the Roseselsa Aurora, I can confidently say it's one of the best budget IEMs I've tried. The tuning is fun, vocals are detailed, the bass has good impact, and instrument separation is impressive. It's comfortable, well-built, and makes every song enjoyable. Definitely worth buying if you're looking for a quality IEM. 🎧⭐⭐⭐⭐⭐
Nice dac
I've purchased this kz edx pro 2 with mic and type c I've received in just 2 days and the product is absolute perfect and build quality and audio experience is so good I've loved it and the look also is so good, the quality of mic is good though compare to other mics audio is perfect and smooth for me.
I opened it fastly then at the end i saw take a video while opening sorry audio store. But tbh the wire quality is so good and delivery also came before expected date. If someone reading this comment the 1 reason to buy from audio store is they keep affrodable prices when compared to headphonezone and concept kart and offcourse amazon and the quality is also on top notch
Great little DAC! Clean, detailed sound with better clarity, tighter bass, and good instrument separation. Compact, easy to use, and a solid upgrade for any IEM.
My first pair of IEM and I absolutely loved it🥰
I’ll recommend the audio store and purchase more in future
I am choosing a well good brand product
The product has a sturdy build and the ring light adds a clean, aesthetic touch that enhances its overall look. Using it with my KZ Castor Harmon Edition feels like listening to my favorite song for the very first time, with sound quality that is clear and immersive. It works smoothly with both Samsung devices and Windows, and the customization options on Windows make it highly versatile. The quick delivery in just one day was the icing on the cake, making this a well-rounded purchase that combines design, performance, and convenience.
Pairing this Harman Target Version with a Samsung A17 playing Apple Music and FLAC files and Fiio X1 DAP as a secondary source with FLAC files. When tuned to give preference to Mids as i prefer to hear the voices more than anything else, this comes out as a sweet sounding combination and tracks like Racy Chapmans Fast Car and Massive Attacks Teardrop shine beautifully. The Castor Pros are best listened at about 40% volume and and infact they do actually sound amazing at a high volume for bass heavy tracks such as EDM but for Trance and Rock the cymbals and snare drums sound better at 40%. This pair of iems and the combo sounds like money well spent so far and next i want to try analytical IEMs like the 7Hz. Thanks to the Audio Store for the rushed delivery.
