dude the least you should do is try them!! you cant just sell them because somebody has told you the westone's are better, thats better for them not you. try them and appreciate them, give them at least a good amount of time of listening because your brain will adjust to the sound, try a variety of music and if they really are not for you then sell them in the as new condition.
you wont lose too much money and its worth at least trying them because they could be the best thing you have ever heard!!!
