the best thing is to go to a large electronics store or headset
specialist shops and try out the headsets one by one; best if you
use your own favourite music track, encoded at a reasonably good
bitrate (mp3 - 192kbs 44100Khz =<, lc-aac - 160kbs, 44100Khz,
wav 1411kbs, 44100Khz, 16bit).
also focus on the dB per Ohm to find out its energy efficiency and
make sure the headset can reproduce the human auditory range of
44100Khz or higher.
