Wow, that's a big endorsement for the MV1. I would like to audit one of these myself If I see them. I did check out their international shipping and was using KSC75 as example the shipping fee came out to be more than $20. That's 20% if a headphone cost $100.
There is a distributor here and there are some retail stores that sell Koss products the choice are however limited. I think more people are familiar to even Skullcandy brand than the brand Koss. They should definitely do better in their channel coverage.
