Turn your M21 into a cassette.
A retro cassette-style case for the FiiO M21 that switches the player to a special retro UI and button control. Player not included.

In the case, the M21 switches to an exclusive retro interface with button control.
Three finishes
Titanium gold, black or blue to match your M21.
A DEEPER DIVE
Inside the Cassette.
FiiO’s cassette-style case turns the FiiO M21 into a retro tape player. It is a protective case with a precise fit and a magnetic opening and closing, light, stylish and made of tough materials, with cushioning to protect the player.
A retro interface to match
The case works with the player through contact linkage. Put the M21 in the case and it switches to an exclusive retro interface with matching retro sound effects, for a nostalgic journey: the touchscreen is paused and you control the player with its buttons instead. Take the M21 out and it switches seamlessly back to its normal system.
