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 had ordered Tanchjim Bunny, amazing service and quick arrival of product before promised date. Totally recommend to everyone.
I really loved the design and detailed view of the iem earphone which I have received, I am so happy with the performance of the earphone, it was like listening to my same old songs like a new detailed enhanced version.. thanks for the product and quality

Good
This cable is great

Product with good budget. Great with my audioculer m61 mp3 player.

This is my first DAP and I have received it in good condition. So far, the music playback is perfect and I am loving it.

Got these after I ruined the cables for my Truthear Nova. Definitely better than the stock cable and the mic quality in my testing was pretty clear as well.
For the price, it's really a great product. The best part is that, many high end DACs do not allow the use of earphone/headphone's mic and inline remote but this one does. I am extremely happy with the product. Thanks a lot for such an awesome product. 👍👍👍👍👍👍👍👍

I absolutely fell in love with this IEM. This is an IEM that made me rethink what correct/natural should sound like. This one has a lot of bass which is good and bad depending on the tracks that you are listening to. The mid range is tonally correct. And the treble is very interesting. Interesting in the sense that there is not much lower treble or mid but there is noticeable amount air and upper treble presence which makes this non fatiguing and also helps percussion instruments cut through the bass. I really love the presentation. The only part where this IEM falls apart is in complex tracks. There it gets a bit jumbled up. And one thing is that you have to play them at higher than normal volumes to truly enjoy them and open up the vocals and treble otherwise they do sound muddy. They scale very very well with volume

It's a 6 star out of 5 star. Just don't look at anything else. Earaudio cables are best. It's neautral and clean and slightly warm because of copper.

It will be hard to believe although I hear a subtle noticable difference in the audio quality from the OEM cable.

It feels like i am hearing the songs for the first time. My first IEM and I am very happy with the sound. Perfect bass, not as much as you get in regular headphones which ruins the song.
Love the way you had packed my product. Also, the product was really good. Had a good audio quality compare to which you get in market nowadays. Happy to be your customer. Looking forward for more products. Thank you.
Good quality cable and sound quality.
The soundstage and imaging in games is awesome. I can hear every minute detail
