Remote controls are a necessity with any CD player, but especially those that hold more than one disc. A good remote will let you program multiple discs. Some players let you play one track or all tracks repeatedly. A-B repeat lets you cycle a segment you've defined. This feature lets you play consecutive snippets, usually 10 seconds, of each of the tracks on a disc.
Headphone jacks with a volume control are the most convenient.
