M23

As an iteration model of the M11 Plus series, the M23 not only continues the classic hexagonal honeycomb design and the 18:9 golden ratio of FIIO, but also sees significant upgrades in configuration, performance, and user experience. It aims to fully create a mid-to-high-end portable Android HiFi player that combines both excellent performance and listening experience
