I like to use my own headphones, so this unit is basically unusable

As other reviewers state, the unit and headphones become inoperable after any amount of sweat.

On my FIRST jog the unit went crazy

Mine is sitting unused at home - I would much rather carry the bigger iPhone to the gym than try to deal with this poorly designed unit.

I hate this unit, and may put it up on eBay for .99 cents.
