Additionally, the MZ-N1 is equipped with a backlit display, facilitating easy navigation even in low-light conditions.

Another notable characteristic of the MZ-N1 is its impressive battery life, offering hours of continuous playback on a single charge. This longevity made it an attractive option for users on the go, ensuring that their music would last through long commutes or road trips without interruption.

Furthermore, the MZ-N1 features a headphone amplifier that enhances sound quality, providing a richer audio experience. The player boasts a range of sound customizations, allowing users to adjust equalizer settings to suit their preferred listening style.
