Bluetooth DAC and Headphone Amplifier 

FIIO’s new sub brand —— SNOWSKY The brand is focused on being youthful, fashionable, unique and fun, while also bringing the traditional FIIO hallmarks of quality and great user experience. RETRO NANO, SNOWSKY’s debut product, is inspired by vintage tape recorders but also packs much modern tech. It is not just an eye-catching Bluetooth DAC and amp - it is a musical device toy that you can explore and relive the music of any era.

Note: Due to the larger memory usage of Android 13, and the JM21 being limited to 3GB of RAM due to cost constraints, it is recommended to only install streaming music apps for optimal user experience. Other apps are not recommended for installation. Additionally, to ensure sound quality and performance, please avoid running multiple apps simultaneously.
