I also would have thought it had made sense with a shorter straight cable. I think for DJ's they will use the coiled when out n about doing gigs but the straight would be used portably. I think it would have been smarter to pick a shorter straight cable, IMO 1.5 m. Two different length cables had complemented each other better, not that many DJ's use straight cable @ while DJing I'd imagine so the length for that purpose isn't really needed IMO. Since these headphones doesn't look like something only DJ's will use I also favor the idea of a shorter (~1.5m) straight cable.
(+1.5m is perfect for me at home ^^)
+1...I agree on the shorter straight cable. Would have been nice to get the best of both worlds. I've been using the coiled cable since I put these on. When I put on the straight cable, I realized how long, and also useless it is. No DJ will ever need to use a cable that long. That is why coil was invented!
