Most units support standard Audio CDs and also list compatibility with CD-R and CD-RW recordable/re-writable discs.
Dedicated transport/ripper models can rip CDs to USB drives or create digital files (including lossless formats) for tagging and management with a companion app.
Some portable players include anti-skip or shock protection to reduce playback interruptions; one model specifically lists 60 seconds of anti-skip protection.
Several units pair CD playback with AM/FM radio; some include cassette decks or recorders. Many also offer aux inputs and headphone jacks for connecting external devices.
Many models use LCD or LED displays (including negative-LCD styles), with on-unit screens for menus on some devices. Several also include remote controls and front-panel buttons for direct operation.
