I use this headset for 1 year
Yes it is heavy, but sturdy. The contour of the ears in cilicone is pleasant which is important for a closed headphone. The sound is fairly straight and neutral and it is great for pre-mix when you can not use speakers. I also use it for recording studio and it's perfect. One of its advantage is that each piece is replaceable.
I prefer it to an AKG 271 studio and highly recommend it.
