I'm listening to Mnozil Brass with fresh erstandenem devil Aureol Fidelity headphones, and it's as were sitting five brass musicians to me: From the high trumpets on the flugelhorn, trombone to bass all lines come completely lifelike, strong but not intrusive. The build quality is solid, a whole set of different sized earpads, a connection jack for a large entrance, a cleaning cloth and a practical carrying case are included. I have 2 other high-end in-ear headphones that were much more expensive, but the devil are clearly the best.
