The most common middle sleeves, e.g. computer and external device are the USB Type A - B cables, where the A connector plugs into the computer and the B plug in the external device. For smaller peripheral devices, mobile phones and tablets, smaller USB plugs were also developed, such as Mini-A, Mini-B, Micro A and Micro-B, as well as a number of manufacturer-specific USB plugs.
Typically, more expensive USB cables are used for Hi-Fi systems for uncompressed digital audio transfer or longer cable runs, as these USB cables are better shielded and with higher quality raw cable/conductors and connectors, as well as with more precise/better assembly quality. This reduces the cables' influence on mechanical/electrical noise, and thereby the data transfer with less digital noise (jitter), which can affect the sound quality or transfer speed.

Hi-Fi USB cables and filters here.
