Okay thanks and I have one more question, I have the Sennheiser HD 518's and these are gonna be my upgrade from them to be used on the go cause I feel the 518's are too bulky and the cord is too long. Do the Pioneers have better sound especially when it comes to bass? Just curious.

Thanks for the responses guys and yes I have considered build quality, I did read some reviews on the skullcandys about the headband cracking so that kinda scares me away from them. But they do have a lifetime warranty which is great, just wouldn't want to have to use it alot. I think I'll go...

I'm choosing between these two headphones to use for portable use (style did play a part in the choices). I have seen many good reviews on both headphones when it comes to sound quality, and now I just need to compare the two. I would really like to know which has better bass in terms of quality...
