Why do you feed your expensive headphones with the sub-par audio from an iPhone A/D converter (probably listening to lossy compressed MP3 in the first place)?

As long as you do that, the pain of having a (free) dongle attached to it kind of fades in comparison.

Maybe it's convenient to have high quality headphones for high quality listening, but then also be able to use that with other devices?
