THE JM21

For the JM21 FiiO has used an aluminum and plastic enclosure with the colors sky blue and silver.

By default, the enclosure comes with a silicon cover and as you can see  compared to the M11S the JM21 is smaller/thinner/lighter.

With the silicon cover removed the JM21 weighs just 156g and measures 120.7mm in length, 68mm in width and just 13mm in thickness.

On the left side of the player FiiO has placed the power on/off button and the volume up/down buttons.

Moving to the right side we find the previous, play/pause and next buttons and the microSD port (supports up to 2TB cards).

At the base of the player, we find a 3.5mm single ended port (PO/SPDIF), USB-C charging/data/audio port,  and a 4.4mm balanced port.

There's also a lanyard opening on the lower right end of the enclosure for people who may want to secure the player on them.

The rear is made of plastic and lists the Hi-Res player compatibility.
