Hi, I know the question sounds odd but.. anyway..
I would want to buy a pair of in-ear headphones for I am trying to seriously learn english. I am surrounding as much as I can with the language: listen to the radio, attending courses, watching tv-series, films, listening to audio books.
The only thing I am missing is a good pair of headphones that perfectly isolates you, to wear while driving the car or walking around the city. I am not comfortable yet with every word: I need a very good isolation in order to understand the speaker at my best...
Do you have any clues? Of course, the cheaper the better :)
