Im sorry if I wasn't clear, the main use is electric music and movies on the road and at home, I want the best sound I can get at this budget, and if it means less portability I dont care.
Then get M50 (or again maybe M35). The introduction of M50x should drive the price down a little.
If you later decide that the longer cord bothers you, send it in to BTG audio for a recable. Note: I found the straight cable version easier to wrap up for transportation.
