Default Koss 60 ohm driver transplants

This thread is here for all of us to mention their interesting Koss 60 Ohm driver transplants. I'm sure we're all familiar with the famous Koss 60 Ohm driver - its the one used in such headphones as the Koss Porta Pros, the Koss KSC75 and the Koss UR-40. This driver has long been considered the "king of the low-end" as it offers performance that is way above its price point. In fact, its been performing this well for about 25 years!!! I think this famous Koss driver really deserves better than the crappy enclosures Koss usually uses it with and I'm not alone in this belief - there have been many people transplanting their Koss drivers into various more or less exotic enclosures, including the Sennheiser PX100, some Sony models and of course various DIY woody enclosures.

I will soon post pics of my own somewhat extreme transplant over here (UR-40 ie. 60ohm titanium drivers transplanted into Koss Pro4AAAT), after my replacement earpads arrive (I want the first pictures to make the best impression they can). In the meantime, please, tell us (or show us) some of the cool Koss 60ohm driver transplants and mods that you have done.
