Headphoneus Supremus
Got my E18 on the sell list if anyone's interested. While it offers excellent sound on the go, I mostly used it in tandem with my MDR-7550 which I recently sold. With the RE400, the difference is not as apparent as with the Sonys. The RE400s are just not that source picky so if anyone is interested at a discounted rate, they're just about 2 months old.
