A protective sleeve made to go over the "jack" of instrument and other cables to keep them from getting damaged and to maintain sound quality.
I just picked up a new guitar chord and it came with Jack Caps for each end.
Wow, my chord is coming apart at the jack, I wish I had some Jack Caps to keep that from happening.

The caps that old men (Pappys) wear. You can tell if the car infront of you is going to be a pain in the butt if the driver is wearing one.
