Although a great fan of Beyer DT100s, I thought I would give these a try. (Used to have K140s, if I remember the reference rightly, as alternatives for studio foldback - not as bulky as DT100s.)
I have used them for setting up sessions, monitoring live recordings, mixing, - and even just listening to music! From both analogue and digital sources.
Isolation is good. Audio quality is excellent, across the frequency range.
They have become my regular 'cans'. Only limitation - a bit large to be portable.
They are comfortable, well made, and easy to use. The detachable - and therefore replaceable - lead is a good feature.
The supplied ?" to 3.5mm adapter screws on, so the lead cannot be pulled out inadvertently - good.
