Great U.S quality built
TRLDEX, 26.11.2020
At this price range it's hard to beat the M4, especially for a device coming from an U.S. manufacturer (this is not a Made in China product!).

My full review can be read here: >
Pros:
- 60dB of gain is more than enough, even the SM7B should work fine;
- pre-amp noise is quite low, maybe not as low as the Clarett 2Pre, but definitely not something that can be heard with ease;
- the ESS DAC chip really shines, so who needs a rather cheap audio interface without noise on its outputs and with a very low THD then this should be the one;
- the OLED VU-meters are a great addition here, probably the only interface adding such VU-meters on this price range;
- case and all knobs are metallic/aluminum, so quite nice to touch;
- all input gain & output volume is digitally controlled, this means there's perfect channel matching;
- no pops in the speakers when powering ON/OFF the interface;
- power button on the back;
- needs no external power supply, it just relies on computer USB power (tested on Win and MacOS and works flawless);
- powerful dedicated headphones amplifier (works even with AKG K701);
- full-scale TRS input plugs that bypasses the gain controls (directly connected to ADC).
- loopback virtual interfaces (made by the Windows drivers) really helps when need to record what you're listening to your computer (could be anything from a Whatsup call to listening music or to audio dubbing a video recording).

Cons:
- VU-meters are a bit slow, but the upper red light peaks are helping a lot when clipping occurs;
- 48V buttons are too close to the XLR mic plugs, when unplugging the mics I tend to press the 48V buttons with my big rounded fingers.

Great clarity and sound for this price
Svarog, 27.05.2020
I'm using this in my home studio setup, connecting two pairs of monitors, headphones and some mics and guitar.
The build quality is great, metal chasis and pots, beautiful LCD display with meters, and rubber bottom pads so it doesn't slip around.

The headphone amp drives my 250 ohm DT990 without a problem. I keep it at about 60-65% while mixing and at about 50% for mastered material and it is loud enough for me, with a lot more gain if you need it.
Sound is crystal clear, which is expected as it has professional converters.
The only thing that bugs me is that there is no volume control for output 3/4, at least no practical and fast way to do it. So switching to my secondary monitors to check the sound is a bit of a hassle.

Pros:
Sturdy build, clean converters, great LCD, two pairs of outputs, good headphone amp.

Cons:
No volume control for output 3/4

Early days but performing well.
Christian3535, 16.11.2020
I spent a lot of time looking for a good affordable USB interface. Most of the reviews I read on other popular brands all mentioned issues with problematic drivers, USB noise and glitches etc. This MOTU M4 hasn't crashed or dropped out on me yet, the drivers went straight in and work with Reaper and Omnisphere. The sound quality is excellent and the drivers are fast and stable giving me low latency for my soft synths without using a lot of processor power. I have a moderate mobile setup using a Microsoft Surface Pro 6 running Windows 10 Pro. This only has one USB socket on it so I've connected the MOTU M4 on it and I've used the MOTU M4 MIDI din sockets to connect my other mobile gear. I suppose I could use a USB hub but I am concerned this migh cause problems. I like the way I have it but I might try a USB hub one day to see what happens. The loopback feature I will be trying next as I like the idea of doing some studio live streams on youtube or facebook and the M4 loopback feature makes it easy to stream the audio to both the internet and M4 outputs at the same time. I highly recommend this interface.

Amazing!
Orim, 01.07.2020
This little black box has it all:
- amazing sound
- very “quiet” almost no noise microphone preamplifiers
- incredibly natural sounding preamps for instruments (all kind of guitars)
- very clever combination of inputs and outputs
- phantom power individually switchable for each channel
- great sturdy build (I dropped it just when unpacking, was moment of terror, but the interface works perfectly) :)
- unbelievable short latency time

I bought it for my home studio to replace constantly problematic Focusrite Scarlett 4i4 3gen (which replaced TC Impact Twin).
Using and abusing it for 3 weeks now, and it just works. Works perfectly well with:
- Windows 10
- MacOS
- iPadOS

I am using it with USB-C cable, but this device works without problems connected to USB-A port (USB 3 and USB2) - tested on my laptops.

If you’re looking for quality interface for your home studio, this one is wort to try.
I am very happy. In the last two years I changed/checked dozens of USB audio interfaces. Always was some problems - either noisy preamplifiers, or non-working drivers, or devices not working after OS update.
This MOTU M4 seems to “just work” :-) I am happy.
