Can't speak for those 2, but I had issues with my Hifiman 400i and the online store I purchased it from (
https://www.electronicsforless.ca/) simply replaced them under warranty, no shipping fees, both ways. It's also common policies for amazon and others. This was a few weeks after receiving them though. Longer term, you're typically dealing directly with the manufacturer and that I don't know... Also had issues with Schiit products though, and they covered the shipping back if I recall correctly.
Did Verum pay for any of the shipping though? Having to pay for both way shipping for the other side the world to get your defective product repaired must really suck... :\ I guess 'free' pads are a nice touch, but if you've paid 40-80$ or whatever in shipping to get your defective headphones fixed, they're not really free after all, probably cost less than the return shipping costs. A warranty in this day and age is just a given, even required by law. Without it, just selling defective products without at least free repairs would be akin to fraud and there would surely be severe, legal or otherwise, repercussions.
