I just got mine in the mail and I had zero problems with the fit. And then I tried them with the cable over my ears and that's where I came across all the fit problems. Normally I wrap the cables around my ears for a better fit, but I haven't had those issues so I'm leaving them hanging.
I tried them out of my a P51, a Pico Slim, an Audinst and the GLite and I impressed with how well they scale up better amps. The GLite was by far my favorite but they still sounded great out straight out of a DAP's jack. Still prefer my full sized headphones, but the isolation is going to be perfect for trips.
