I use this headset for almost a year. For headphones designed for DJs, it is not top its flexibility (the headphone Official Sony all the Dj's, is much more flexible!), But those who have broken are really raw, and I wish them luck with their turntables!
For it is not fragile as long, and pulls no evidence as I have read it is a Sony!
I do not recommend it more for MP3 players or other, as its cable footprint (~ 3 meters?) Is really designed for applications dj and prod.
So, balance sheet, price / quality ratio very correct, it covers a very wide frequency with a clear and well distributed (and then must not dream, it's not worth to € 200 in a headphone that is used primarily - I speak to beginners - to stall a tempo!).
Only real complaint flexibility, and yet it is a very good headphone.
