A couple of questions that I'm sure aren't too tricky, but are bugging me.
First, I know that iOS headphones can't be used with my 7 without h/w mods, but I'm still uncertain on what 'phones can be used, especially bluetooth models. Specifically, the Arctic Sound P311 interests me but I can't find confirmation that they'll definitely work with the 7. Anyone have experience of them? Or recommendations on cheap'n'cheerful travel-friendly equivalents?
My second question may be a silly one, but is there any difference between USB cables? I wanted to get a second, spare, cable for charging the tablet and today found an extremely cheap one but don't want to use it if it's gonna blow it up. Or whatever.
All answers will be gratefully received.
Thanks!
