I know. Very user friendly clipped on the outside of my pants pocket. Easy to skip tracks without looking. But if I'm walking around and doing stuff and bend the wrong way, it pulls loose easily. No more hard yank at my head.
But yeah. The cost. I was also thinking the other day that if I was going on a trip where charging would be a problem, just buy an extra one as an alternate for when the battery runs out.
Just strap an army belt of external USB battery packs around your waist like JK1 does.
JK1 is a fascinating fellow.
