First off, these are durable! I have already AKG K141MkII, and compare this two i must to say Superlux HD-681 B hold on its own very well especially when thy cost a lot cheaper. I used these to check my work from professional monitors and I'm surprised when I check with these because they're so flat. For the price, there is no better product! For a headphone to sound this good for such a low price is nothing more than a bargain. The clarity of music and separation of instruments is something i was greatly pleased with, especially when listening to soft rock, ballads or similar music. Naw on comfort - the elastic headband makes easy to find the correct position. The standard ear pads are very big and don't apply any unpleasant pressure to my ears. Thy OK for wearing on head for a couple of hour or so...maby even more - i just don't use headphones more than that..feu hours then pause..
Overall they do sound really great, by it..thin nobody will regret!
