I find them a bit boring compared to some other headphones, or at least compared to others I own. They are very competent tonally (and come with tuning pads for minor adjustments), but they lack the impact and dynamics I would normally look for. It doesn't lack bass, but it has a somewhat polite feeling and presentation to it.

As I described it to a friend once, it's like a butler was bringing my music to me rather than a normal waitress. It's the same song, just more polite
