I just look at it like this: where other headphones are so comfortable you forget you're wearing them, Grados are as comfortable as they can be and still deliver their awesome sound

If mobile use in a public space is important to you then don't purchase Grados (unless you want an in-ear, which would lead me to recommend the excellent GR8 or GR10 from Grado).

Grados win again for me

But I kept reading how good these Grados sound

While some will prefer a tighter grip, the Grados never feel loose-fitting

Where other headphones are laid back and accurate and will relax and lull you, Grados will wake you up, energize you, and make you take notice

Because although Grados will do fine on straight line outputs, they like the extra power and really sing with more headroom

Pretty much everything, from the grinding of a bow on cello strings to the breathing of pianists and artifact noise on small audio files, all bloom as if someone just put them there afterward, and loud and soft sounds suddenly give music a more rollercoaster-like experience
