They are isolating all noises around really well, I'm able to listen to music on low volume and I can still hear everything clearly.
At the same time they still breathe which makes them one of the most comfortable headphones in that price range, their size is good and they fit perfectly on ears, default pads work nice (additional velvet pads are included for those who need something with softer touch).
I use them with coiled cable (it's also included) which allows me to keep my workplace out of unneeded additional cables lying around.
Overall quality is good - they are made out of durable materials (unintentionally dropped them & pulled the cable few times and I can say that it's impossible to destroy them during normal work)
If you are looking for good studio headphones - you are in the right place.
