First of all I want to say sorry for my English . I am watching for a new pair of headphones over-ear for under 250$. I want to use them on the bus so they must have a bit of noise issolation. I also want to "fold them together" that I can store them in my backpack. I listen to electronic music but also to rock,... (A lot of styles). (They must be available in Belgium). Can someone help me to find the right ones?
