Care Guide
The FiiO SK-M21C is a cassette tape-style case exclusively for the FiiO M21 (case only). The M21 unit is sold separately.
It has been opened for confirmation but is unused.
The SK-M21C is a specially developed and customized cassette tape-style protective case. When the M21 is attached, it automatically switches to a retro UI. Furthermore, by turning on the retro sound EQ installed on the M21, the SK-M21C's design and the M21's sound will evoke nostalgia for the golden age of cassette tapes. When the protective case is removed, it seamlessly switches back to the original system, providing smart and comfortable operation.
《Features》
● Made of highly rigid and transparent polycarbonate material, balancing portability and visual appeal.
● Implements a dedicated UI and EQ that allows you to re-experience playing cassette tapes. (*)
● Intuitive and easy attachment design, like inserting a cassette tape.
● Internal protective padding securely guards the unit from impact and abrasion.
* When the SK-M21C is attached to the M21, dedicated terminals come into contact, enabling multi-function, volume adjustment, playback stop, and track skipping. Touch screen operation is disabled while attached, and operation is done via physical buttons.
