Making playlists on Fiio X1 is a very tedious task

but probably more rewarding that comparing power cords

Finding an on-ear headphone for portable use is a challenge. They tend to be out of the price range that I would be willing to pay,too bulky,don't fold,a seemingly lack of durability or desirable sound quality. Right now a Beyerdynamic T50p that is heavily EQ'ed is winning only because it meets most of my criteria but it is not that satisfying.

I can only see doing a power cord upgrade (is that even worthwhile?) with my custom desktop computer but I am long way from actually doing it.

Unless you're looking for throw-in-backpack-and-not-worry build quality (V-Moda), I've found the Thinksound on1 strike a very good balance in portability, efficiency, and sound, especially after some simple mods. They're discounted right now on Amazon ($214) and may even go lower during black friday.
