I bought myself a new AUX cable by Belkin, but after plugging it in I discovered I will need to either buy an adapter or change my case as the aux cable's jack is too big (or the case's slot is too small...) and I simply can't push it all the way through. First of all, I am (or used to be) a big fan of my Neo Hybrid, because it gave me just enough protection at the same time being considreably light, but do all Spigen's cases have the same issue with the headphone jack? I mean, if I were i.e to buy Ultra Hybrid or Slim Armor would I encounter same problem with fitting my jack without an adapter? Second of all, I was trying to find a suitable adapter, but online it seems quite hard to estimate if it's going to fit in or not... I.e this one: link. This is another one I found, but it says there it's 2.5 to3.5 mm, so I guess it won't work? (I'm sorry for asking dumb questions, I guess I've never been a headphone jack expert..).
