The sound is just amazing, no matter the volume, it sounds always correct precise and crisp on. However, one should not expect too powerful bass because of KH is tuned neutral - but that was indeed mentioned already to suffice.
In my opinion, one should mention that the Aureol no headphones for being "on the road" in the classical sense. Who does not want to forfeit during a train journey or on the bus with the neighbor, should blast the music in no case here - the headphones are built open, meaning the sounds from the inside penetrate almost unhindered into the environment and just the other way around. Therefore, my opinion is the area of application on the sofa rather than on the road.
Otherwise, just buy it - I give my no longer here!
