NEW JadeAudio/FiiO JM21 Android 13 Hi-Res Music Player MP3 with Snapdragon 680, Bluetooth WiFi USB DAC 12.5H Playtime
(Black) 3G+32G
(Black) 3G+32G
Condition: New
Patented Desktop Mode, Specialist in Battery Protection
The M21 is the first entry-level FIIO digital audio player to implement desktop mode.
When desktop mode is enabled, the M21 will only operate on power from an external power source.
The built-in battery is neither charged nor discharged, so it can be used safely even while powered without draining the battery. This extends battery life and prevents performance degradation over time. Long-term use at a desk will not affect portable use time
Portable and desktop, performance is dramatically improved by selecting the mode
In portable mode, it operates at standard voltage, while in desktop mode, you can select "Super High Gain" which allows high voltage operation.
