Fun fact: if you measure Verum One without an ear model at all, and only using a flat foam coupler that absorbs all reflections, the frequency response is an entirely flat line from 10Hz to over 10KHz. That means that all the variables and bumps in the FR comes from how the reflections interact with your ears. Pretty insane, really. Different pads will tame different bumps in different places. ZMF lambskin pads (I chose Auteur pads) lower the 1KHz bump a lot and make the transition to the treble much cleaner. It also boosts the area from mid bass all the way up to the mids a little. It also lessens the bumpyness of the treble so it's flstter and smoother. The sub bass changes are miniscule, but it drops off a little more than with the airtight pleather pads. I would kill to try pads that had pleather outside, microsuede towards the face, and velour inside. The Cascadia Impact pads are on my list of pads to try out. If you have problems with the treble, they are so incredibly linear that you can just put a few layers of felt over the driver to adjust it, and you won't lose a lot of detail in the highs like you will with many dynamic drivers. I also EQ mine, as I do with all my cans, because I can. I mostly just refine the FR so it's really smooth and linear, and then I apply my own preferred target curve. Not a big change, though!
