Two V360 problems (Video, headphone port)

When I take videos, it seemingly stops recording at random times, why is that?

and the headphone port seems too small for regular headphones, whats going on with that?

Well my Motorola V635 does that sometimes, changes video length by a few secs.

As for the headphone jack, it is 2.5mm size.

so how do you get a headphone to work on it?

You'll have to find a headset with a 2.5mm jack. Also you might be able to find a adaptor that converts a 2.5mm jack into a 3.5mm jack.

Get a bluetooth headset, once you go bluetooth you don't wanna go back to the regular headsets
