So, today i walk to a local Sony Store and ask them if they still have a leftover stock for old Sony HPM-83 headset. And they have one, and they even have no idea how much this thing were. They ask me 5 bucks for it, but i'm being a cheapskate and ask them 4 bucks of it with 6 month of warranty. They agreed, suprisingly, and now i ends up with one of the best 4 bucks i ever spent in my live.
