Classic Tube Charm with Modern Transistor Power
Meet the xDuoo MH-02. This DAC/Amp merges old-school tube charm with modern digital muscle, giving you the best of both worlds. With the soulful warmth of tube amplification and the crisp, detailed transients of a Class-A transistor buffer, this hybrid amp delivers music the way it’s meant to be heard—warm, rich mids combined with treble that sparkles with detail.
High-Resolution USB DAC Decoding
Plug in the MH-02 and get ready for an earful (in a good way). This little dude decodes high-res audio up to PCM 32-bit/384kHz, DSD256, and MQA 32-bit/384kHz from any device you’ve got lying around. Thanks to the CS43131 DAC chip, you get crystal-clear decoding.
Hybrid Amplification: Tubes Meet Transistors
All hail the hybrid amp. The MH-02’s double 6J1 tubes give you that smooth, warm sound that makes everything feel like a lazy Sunday morning. The transistors, on the other hand, bring the muscle, with a Class-A buffer that delivers both low-end oomph and high-end sparkle. It’s like putting a rocket engine in your grandma’s Buick.
Powerful Output for Any Headphone
With 1300mW of output power, the MH-02 isn’t messing around. High-impedance, low-impedance—doesn’t matter. This thing can drive whatever headphones you’ve got.
Adjustable Gain for Precision
Do you have finicky headphones? No worries. The MH-02 has a gain switch that lets you tweak the output to match your headphones’ impedance. High gain, low gain—just flip the switch and you’re set.
Versatile Line Out for Pre-Amplification
Need a pre-amp for your gear? The MH-02 has a line out that runs through the tube stage and is controlled by the volume knob. Hook it up to your amps or active speakers and hear your sound quality jump up a notch.
Ear Protection with Built-In Circuit
No one enjoys a loud POP when they turn on their gear. The MH-02’s built-in relay mute circuit ensures you won’t have to deal with that nonsense. It keeps your tubes happy and your ears unscathed. Easy, breezy, and totally hassle-free.
Elegant Design
Wrapped in a sleek, sandblasted, textured shell, the MH-02 isn't just about great sound—it looks fantastic too. Simple, clean, and ready to blend into any setup without shouting for attention.

I was looking for IEM Tangzu but they were loud and bass was little low as per my ears.Owner or Associate at store suggested me Audicular i liked the sound as well as bass effect its great product.
The Sennheiser IE 200 delivers impressive value for the price. Comfort-wise, they’re lightweight and fit snugly thanks to the ergonomic design and included foam/silicone tips—great for long listening sessions. Build quality is solid despite the plastic housing, and the detachable braided cable adds durability. As for the sound signature, it’s balanced and clean—tight bass, clear mids, and smooth treble without harshness. Bonus points for the dual-tuning feature that lets you slightly tweak the sound. A fantastic entry-level choice for anyone looking to step into the audiophile world.
There sound is pretty good
Good quality
a very well made cable from Dunu with modular plugs and a very secure fastening system (q lock), no microphonics noted, contrary to many reports, usage : Shure se215 + 4.4 plug + Hiby r4 and it really opens up the Shures and the over ear loops are very comfortable too
This is really warm sounding as advertised. Especially vocals are more engaging. The fact that its driven by phone power doesn't affect the sound quality in anyway like in other dacs I have experienced brighter, thin sound or few peaks in upper midrange. If earphones are having good sensitivity then this dac provides good enough power. Although bit bulky build is very good. I'm sure it can withstand frequent drops also. Have not tried the filters and listening to default filter only. One thing I noticed is although on paper power output is good for 32ohm its only good at driving earphones and not headphones. Distortion kicks in when volume is increased even at high gain setting. I'm only guessing current supplying capability for dynamic driver headphones is not sufficient. Tested with 300ohm HD600.
The sound quality is so much better than any other wireless earphones
The quality of wire is superb.
The mic quality is also good.
Length and feel of wire is good. Sound quality with my Tangzu warner is excellent

Have bought this on 17 Aug 2024 and after using it for almost half a year i can surely say this is the best one in this price range...
I like how crisp and clear the audio is, also how good the IEMs respond to EQing, which unlocks a lot whole lot of possibility

Recently bought this after seeing some positive reviews
Fit:
Unlike many reviews which talks about it's fit issue, it's a wonderful fit for me with the stock large size narrow bore tips. I usually go for medium or small size silicone tips but for this one large one fitted well. i guess large size long stem eartips fits well with this iem.
Sound:
Vocals and string instruments sounds forward but never thin or sharp or fatiguing and has a sweet timbre. I guess it's due to its thick note weight and the quality of dynamic driver.
Bass in general is good. But i would prefer little bit more sub bass quantity. Also prefer the bass to be a bit tighter. Not too tight as i am not a fan of too tight bass. Basically here bass decay is slow and i would prefer it to be moderate.
Treble has just enough energy and details but relaxed.
Overall it sounds very nice with a pleasant timbre.
Note that i replaced the stock cable with fiio ls-b 4.4 mm cable.

Great set to start your tip rolling journey!
Got the delivery under 24 hrs.

This is wonderful product and quality is great. Very good working with mic.
And support samsung s22 ultra.
The Moondrop Blessing 3 is a hybrid IEM with excellent performance and a largely neutral sound signature with a slight bass boost. It offers impressive detail retrieval, resolution, and instrument separation for its price.
Pros:
* Excellent detail and clarity: It reveals subtle nuances in music.
* Balanced sound: Largely neutral with a well-controlled bass that doesn't bleed into other frequencies.
* Good technicalities: Strong imaging and separation of instruments.
* Comfortable for wearing for long periods
* Solid build quality
Cons:
* Fit can still be an issue for those with smaller ears.
* The cable could have been better.
Overall an excellent IEM for me.... Well done Moon drop!!!
The KZ ZSN Pro 2 offers exceptional sound quality at an affordable price. With a hybrid driver setup (1 dynamic + 1 balanced armature), it delivers a punchy V-shaped sound signature with deep bass, clear mids, and sparkling highs. The soundstage is surprisingly wide with good instrument separation and imaging. Build quality is solid, featuring metal faceplates and a comfortable, ergonomic design. While the cable and accessories are basic, the overall performance makes the ZSN Pro 2 a fantastic value for budget audiophiles.
