THE M23

The 299g heavy M23 (329g for the stainless steel model) measures 136.5mm in length, 75.7mm in width and 18.1mm in thickness (without the silicon case).

To have a better idea about size I placed the M23 right next to the M11S and the M15.

On the left side we find the power button (there's a RGB ring around this button which changes color according to audio codec and content quality), volume touch panel, and a multifunction button.

Moving to the right side here we find the back/play-pause/forward buttons, desktop mode switch (external power required) and the hold switch (locks out all buttons).

Two USB-C ports (power in for desktop mode and charging/data) and a microSD card slot are present at the base.

At the top we find a 3.5mm single-ended in/out port and a 4.4mm in/out balanced port.

The rear of the M23 is polished and features numerous logos.

FiiO bundles a basic silicon case with the M23 which gets the job done.

Here you can see the power button and its RGB LED (blue for lossy tracks, green for SQ lossless, yellow for HR lossless, purple for MQA and green for DSD).
