SMSL M20 Review

Another highlight is the LEDs surrounding the unit. These LED lights illuminate during use and serve as indicators for volume and even navigation assistance. It’s a flamboyant decision since many gamers like to play in dimly lit or dark rooms, and these lights aren’t exactly subtle.
That said, there’s a feature that allows you to turn them off. In well-lit environments, LEDs are not overwhelming, and I kind of like them. They look very “cyberpunk” combined with the naked internals.
On top of the unit are three buttons: a red button on the right for menu selection and two black buttons for volume up and down. They are tactile enough, though the feel is closer to a soft click than a mechanical press.
These buttons handle filter switching, output mode selection, USB UAC mode, filter selection, and MQA mode without the need for an app. The “menu” is actually on the bottom side of the transparent top panel.
You get assistive LEDs to know what’s what. The usage is simple, although the labeling is hard to read due to the small font size.
