Looking for affordable bluetooth headphones working with iPhone 4S iOS 5.. Going to be exercising quite a bit this summer and the wired headphones are a pain in the ass when using a jump rope or trampoline. I will mainly be doing podcasts and audiobooks; so I had a few questions. - Will the single piece headphones (the kind that business douchebags use for making calls in public) work with audio on a non hacked and modified OS? Like I said, I don't /need/ 2 headphones *even though I would probably pick them up anyhow* - What ones do you use? Do they have a returns policy (headphones tend to **** up around here)? - Do you buy them online or in store? Sorry if this isn't the correct forum; I didn't know where else to put it.
