I originally got to test this at AXPONA in Chicago, and the little device really was a lot of fun. I'm not much for the little games or graphics on the back display, but I have it pretty much always set on the VU-esque volume meter, or have it off.
But the sound is great! I was able to power IEMs with ease, but also more power hungry headphones like the i5 planars, or the Grell OAE1. I've been carrying it with me most everywhere I go instead of my ipod pros, and that is a high vote of confidence that I'd rather trade the music fidelity for the ANC of the ipods.

I mainly use wired IEMs, and MD3 makes the whole experience effortless. Better sound, better power, and no annoying dongle hanging from the USB port.

Being able to charge the phone while listening is huge. My old dongle forced me to pick one or the other, especially during long flights and workdays.

I've lost count of how many times I've accidentally yanked a dongle DAC while pulling my phone out of my pocket. The magnetic attachment keeps everything secure and feels much cleaner for daily use.

I was worried the display was the main selling point, but after listening for a few days, it's clear the audio performance wasn't treated as an afterthought.

Functionally and practically speaking its a great product that does everything it promises, built in magnetic support and the screen is a great convenience. However it absolutely refuses to play nicely with my Samsung phone, one workaround is to use the charging usb port to connect my phone however then I cannot using the passthrough charging feature, this workaround also doesn't always work preventing me from using my MD3 on my phone completely. Cannot recommend if you primarily use a samsung phone for listening (not sure if other devices are affected). Hopefully a firmware update will fix this and change my outlook to an easy 5 star review.

I’m not really a professional sound user but I have notice that it makes my music listening sounds much cleaner and available to distinguish the instruments in the background. Great product overall

Estupendo DAC portátil, transparente, nítido... profundo y con buen paisaje. Cómodo y fácil de configurar, perfecto para el día a día, junto a los IM4 con cable balanceado o no, no querrás dejar de escuchar tu música preferida, ya sea clásica, jazz, folk, blues, rock o cualquier otro estilo.

The magnet doesn’t work through a case and barely attaches without one. The magnet can’t support the weight of the cord for my headphones. I used to use a Earmen DAC and the Fosi definitely sounds better. But I bought it for the magnet and overall I am disappointed with my purchase.

Compact and light for its form factor, and like the animated screen savers

Other than the sleek look and idea , don’t really see a difference it made when it came to audio . sound is tinny and not really an upgrade to listening straight from my phone(iPhone 16)

It has a great design, and is very portable making it the perfect on the go IEM companion

No esta mal, pero a la hora de subir el volumen no se puede subir con el dispositivo que seria lo mas intuitivo, hay que subirlo en el md3.
Ademas su volumen es bastante bajo en comparación con otros de la competencia como por ejemplo en FiiO ka11 que tiene una respuesta de volumen bastante mejor

I currently own a Fosi IM4, DS3, MC 331 and now the MD3. They are all really good at what they do. Some days I grab the DS3, others the MD3, the passthrough USB-C on the MD3 is really helpful, and being MagSafe too. I will definitely be adding to my collection when I van afford it!
