These look all around good to me, they got great reviews and are a very good seller on amazon.
The Sony's got a lot of good reviews and look very comfortable, but I did get some advice from an audiophile who said he auditioned them and said they were total rubbish. So I'm kinda confused here. I did some research and to be honest these got a lot of good reviews from a bunch of different places. I heard the bass was unbeatable but the mids and highs were not so good.
The same audiophile that told me the Sony's were rubbish suggested the pioneers. There a litle more than I want to pay but not by much.
I did some research and found out that the panasonics where cheaper and had better mids and highs but still can't compete with the thumbing bass of the Sony XB500s
I'm not an audiophile but I do have respect for good sound quality and to be honest i am learning toward the sony XB500s sense i love bass and all i listen to is dubstep and some rap. I'm open to your opinions. NOTE: I do not plan on going out and buying an amp. I just want to use these headphones to listen to music on my iPod touch.
