A micro SD card must be "unfortunately" bought later. A high storage capacity is not recommended. While acknowledging the MusicMan memory cards up to 32GB, but missing a small display, etc. to access directly to song titles. There remains only the possibility of a single song via forward or Rewind button to search. Capacities over 8 Gb are therefore absurd, because the search else can easily degenerate into an endless employment. It makes sense, therefore, is to buy more SD cards with a smaller capacity. Another small drawback is a lack of shuffle function.
For small parties, traveling, beach visits, etc. the MusicMan is fantastic. Thanks to its performance and its relatively crystal clear sound can be unceremoniously sound for smaller rooms.
Despite these shortcomings, the device is highly recommended! For a small price you get delivered high quality.
