Excellent former top of the line headphones from Beyerdynamic
Dynamic W shaped forward sound signature with decent resolution. Very good sound stage for closed-backs. I much prefer this to flat neutral headphones. Good sub-bass with slight bass bloom and not as detailed bass when compared to other premium headphones such as Fostex TH-900mk2.
Excellent sound isolation with not too much clamp force. Lightwieght and comfortable for a several hours. Great for travel. Lots of aftermarket cable options as the headphone connections are slim 3.5mm style. Very tough and robust design.
Bought as a back up vice and works well. Obviously smaller and not as stable (or heavy) as full sized vice but perfectly suitable for freshwater flies and smaller saltwater patterns at a push. Fully extended it is 7" to 8" tall.
The fact that it can break down into a small flat box 6.5" long means it is ultra portable. I like the fact that it is easy to get spare jaws and parts for it also.
Terrible backing. Its 3 times as thick as the equivalent Orvis and SA backing. There are unexplained fraying in several places along the 200yards length. I stripped it back off the reel and binned it. Then ordered Orvis Backing.
