The FiiO SK-JM21 is a protective case made for the FiiO JM21 player, in eco-friendly PU leatherette with an inner steel ring frame, raised button covers and a Velcro top flap. It suits JM21 owners who want a fitted, wear-resistant cover in blue.
Who the FiiO SK-JM21 is for
JM21 owners: FiiO designed the SK-JM21 specifically for the JM21, and it works with either the pre-installed PET screen film or a tempered film.
Daily carry: FiiO says the PU leatherette resists wear and dirt, and an inner steel ring keeps the case from deforming.
Wired listening on the go: The bottom headphone jacks and USB-C port stay uncovered, and the Velcro flap keeps the player from slipping out while you plug and unplug headphones.
Button feel: Hot-melt raised button covers give clear, accurate button feedback through the case.
Skip it if: you own another player such as the M21 or want a screen film included; the case is cut for the JM21, and the SF-JM21 tempered film is sold separately.
