Bluetooth headphones for running?

[Tcrumpen]

Part of my daily commute is a 1.3 mile walk/run to and from my office and i'm currently using wired headphones which because of them snagging on my hands or fingers from time to time are slowly breaking the headphone jack on my phone, even though i plan to be buying a Fiio M3 soon i still will use my phone as a backup device and therefore as much as i might hate the whole bluetooth headphone craze i'm in the need of some to make sure that my headphone jack doesn't break any further

 

So i'm in the need of some suggestions, my budget is up to £50 (approx $70), as these will be commuting headphones, i don't want to pay top dollar for them, i am willing to loose some audio quality for easy replace ability
