Does iPod Classic 6th Gen support a headphone remote for pausing/playing, adjusting volume, and advancing the track?
I know that the 7th Gen does support this feature, and my iPod video (5th Gen) does not.
iPod classic, Other OS
The listing for Apple's EarPods

under Compatibility, shows it supporting back to "iPod classic 120GB (2008)."
The official list of iPods does not actually name iPods after the 5th gen model by a "gen" name, but if you look at the list

it is clear which one "iPod classic 120GB (2008)" refers to. There is an earlier "iPod classic" ("6th gen") model from 2007 that is apparently NOT supported by the EarPods. But it's possible that Apple's older headphones with remote control works with it.
