Judging a headphone by specific codec support just doesn't make sense. Support for acoustically transparent codecs is good enough. Nobody has every demonstrated an ability to reliably distinguish high bitrate mp3 or AAC from lossless. There are still benefits to lossless from a preservation perspective, but for actually listening to music it really doesn't matter.
