    Hi there, wondering if anyone can give me some advice. I have someone offering to sell me Koss Pro/4X but cannot find anything really substantial. Are the Pro/4x's good headphones? I have seen good things from the Pro/4AAA version. I do listen to a lot of music with good bass so I am wondering what the difference between these headphones are? Thanks for any help/advice!
