Well many _tools_ look like they've been designed in a cave without light but do their job better than those "megaparty 8000 with x-tra glitter" toys.
HD25-1 is going to be my next set, been playing with Pioneer 5000's and I get a headache because they're so heavy and not padded enough on the top arch. When playing in a club etc, you really don't have time to enjoy the sound quality through your headphones, that's why there should be a good set of monitors (Bosc's or komodo;) in the booth. I mainly listen to music from headphones at night when my wife is sleeping, so I need good sound that can be weared for many hours. At day time my crappy speakers will do the job.
Buy quality, that's the way to stop the crap from being produced.
Dj headphones are not build to withstand cold, plastic shatters very easily in -15C. Keep those wires under your jacket.
