My main reason for not wanting the beats headphones is that I much prefer the small in ear ones - how do people carry these big bulky headphones around with them all day without either being super annoyed by their size or accidentally crushing them?
I like the 20-30 EUR in ear headphones like these but I am not brand loyal at all, right now I have Philips:
Nice and soft to work well for my ears, cancels enough noise but still can be worn while walking around outside (no car = lots of time in public transport) and cheap enough that I don't mind replacing them once a year after they inevitably break due to wear and tear
