I know there is already another topic on this but I thought I would ask anyways. I was checking on the availability today of the S4 and noticed that the Custom 2s are actually the same price. It's tempting to go for the Custom 2s because I expect a $200 pair of headphones will outperform an $80 pair, but I suppose each has its own pros and cons. I am a student and I use public transportation often because of this. My old iPod headphones just don't really cut it while trying to blast over the sound of the bus. I would also like to be able to use my headphones for active use, like running or biking. If type of music makes a difference, I am very diverse with what I have. I'll swing from hip-hop right to acoustic to rock and back again. I also won't only be using these just for transportation. I'll plug them into my laptop while studying or into my ipod while waiting between classes. I was sold on the S4's before but I'm having second thoughts now.. HELP! Thanks everyone!
