Hi! I'm still pretty new here. I don't mean to hijack this thread (my question is still pretty relevant), but my own post didn't get too many responses. As a result, I am still unsure of what headphones to buy. I have so far picked out the Superflux 681, Panasonic RP-htf600, JVC HARX700, and the AKG K518 LE. I am open to any other suggestions. I mostly listen to rap, pop, r&b, and occasionally classical music. These will be used with my iPod, phone, and sometimes my computer. I do not have any amps. I do have a $40 limit and would prefer to buy from Amazon because I have a $35 gift card. I need to use this out of the house at track meets. I was going to get the Superflux but someone said that they are great, but not very portable. I am thankful for any help that can be provided.
