UPDATE:
Too bad the owner/builder turned out to have such a demeanor. I bought mine before all the flap arose.
In any event, I feel fortunate to own them and enjoy listening to them very much every now and then, especially with an all tube amp.
They sound first rate in their clarity and accurate timbre yet they lack the slam and drive that some other headphones have. Also, I experienced distorted sound on several classical piano concerto recordings and it turned out to be the sound of the earpad magnetic metal rings resonating. I fixed this by removing the metal rings and using small glue dots to hold the pads in place over the drivers. I experienced the same issue with the original liquid wood Nighthawks and it was caused by the vibration of the plastic earpad rings that came with the Nighthawks. Once the rings were removed, the ugly reverb resonance and distortion went away.
The pads listed below sell for only $10.20US per pair and are less thick than some of the pads others have been recommending, which I find curtail the Verum 1's midrange magic. The inexpensive YDYBZB brand protein leather pads improved the overall sound of the Verum 1 even more than the pads that came with the Verum 1 or the optional perforated OEM pads that I purchased from the Verum website and even bested higher priced pads I have tried.
