The JOLIKE M4 Music Player is a versatile portable device designed for a rich audio and visual experience, offering a range of functionalities beyond just music playback. It features a 2.4-inch TFT Full Touch screen, providing an intuitive interface for navigation and control.

Function Description

The primary function of the M4 Music Player is, as its name suggests, music playback. It supports a wide array of audio formats including MP3, WAV, APE, WMA, FLAC, and ACC-LC, ensuring compatibility with most music libraries. Users can access their music through various organizational categories such as "All songs," "Last played," "Artists," "Albums," and "Playlist." The device also supports a "Local folder" view, especially when a TF card is inserted, allowing for direct file browsing. Playback modes include "Sequential Play," "Single Cycle," "All Repeat," and "Shuffle," catering to different listening preferences. Music control is comprehensive, offering options to play, pause, skip to previous or next songs, rewind, fast forward, change play speed, add songs to a favorite list, and access song-specific settings.

Beyond music, the M4 Music Player also supports video playback. It is compatible with AMV and AVI video formats. Similar to music, video files can be accessed from local folders or a TF card.

Another key feature is the FM Radio, which allows users to listen to their favorite radio stations. The device offers options to save presets, auto-tune, and record FM radio broadcasts. Users can also select different tuner regions, including Common Band (87.0 MHZ ~ 108.0 MHZ), Japan Band (76MHZ ~ 90MHZ), and Euro Band (87.0 MHZ ~ 108.0 MHZ).

The M4 includes Bluetooth connectivity, enabling wireless audio streaming to Bluetooth speakers or headsets. This enhances the listening experience by removing the need for wired headphones. However, it's important to note that the M4 cannot pair with smartphones, and ACC-LC music format is not supported under Bluetooth playing mode. For FM radio listening via Bluetooth, wired headphones are required to act as an antenna.

For file management, the device features a "Folder" function, which sorts MP3 and SD card memory by edit time, with the most recently added file appearing at the top. Renaming or modifying files will move them to the bottom of the list within this view.

The M4 also serves as a "Recorder," capable of voice recording in MP3 and WAV formats. This can be a useful tool for classes, speeches, or meetings.

An "E-Book" function is available, supporting ONLY TXT files, allowing users to read text documents on the go.

Additional functions include Photo viewing, a Stopwatch, Alarm, Calendar, and Theme customization, adding to the device's utility beyond its core media playback capabilities.
