I never had the opportunity to listen to them before purchase, but I went ahead anyway, since I love my Focal Twin speakers and needed an extra pair of closed back headphones for both recording and reference. The fit is ok and the leakage is low. However I feel there is something going on in the mid that makes them feel somewhat lackluster, boring and "nosy" for lack of better words. I most likely won't be using them for mixing and stick to my Beyerdynamics and Akais for that. In hindsight, if I had been able to listen to them beforehand, I would have gotten something else.
