Yes, but I believe kstuart is talking about testing headphones for review and/or recommendation purposes, not personally using them for enjoyment.
That said, I'm guessing kstuart is right about the need for a reference. After all, that's how visual equipment (like televisions and monitors) is calibrated and tested: with test patterns and color swatches. You can verify the TV looks good with your favorite movies and games afterwards, but there does need to be some sort of reference or standard as well -- and I'd assume this would/should apply to audio equipment such as headphones too. (Disclosure: I've been a videophile for longer than I've been audiophile, and would still actually consider myself much more the former than the latter.)
That said, I myself have pretty much sworn off headphone reviewing because I'm not into enough genres.
