I find most of the Beyerdynamic higher impedance headphones (including the DT770/DT990 Pro 250ohm) sound very different (especially lacking bass + sub-bass) when you try drive them on a phone. For transparency, most of my testing of this has been on slightly older phones (around 2-3 years ago) and most of the newer models don't have headphone jacks.
Other phones I've got which are not driven well include: Senn HD800S, most planars including {Hifiman HE1000, Hifiman Arya, Audeze LCD-2}, .
With one of the planars I own (the Dan Clark Audio Aeon 2) I've listened to them on an iPhone with an AudioQuest adapter and it sounded fine, but still the dynamics seemed much better on a proper amp.
