I use DT880 Pros. Kim uses DT770s, I think. I’ve also used AKG240 Studios and Ms.
Beyerdynamic is indeed the same company that makes microphones. The Sennheisers IMO do not sound anywhere near as nice as the Beyerdynamics.
DT770s on Amazon @ $180 if you want closed back (250 Ohm model).
DT880 Pro @ $240 if you want semi-open (250 Ohm model).
