Time for an absolute chonkster...

National (Technics) EAH-88 (1972*)
2-Way Headphone

did someone say crossover?

I can't remove the 'smaller' 50mm driver as it's glued in.
BUT - looking through the front grills it appears to be a mylar-dome with a fabric dust cap.

Still pretty cool looking, it does look it's trying to be a coaxial, but it's not

This version has 'Sennheiser' embossed into the dome.

It reminds me how some Koss like the dynamic 10 have their logo embossed on the dome as well. I wonder if it causes any sound differences?

Sennheiser HD540

looks just like the HD250 Linear and HD560 driver.

Leftover test wire?

Apart from the driver themselves, I'm surprised at how different the mounting and construction is. I expected them to be more similar

Elecom HS-ARMA100BK

Titanium coated 50mm driver

Sony MDR-V6

Not sure how old this one is, but it's Made In Japan.
It looks like it has a dark coloured coating on the driver magnet.

The ultra sticky foam cleans up REALLY nicely with only isopropyl alcohol.

Sony MDR-CD999
50mm
Amorphous Diamond Deposition

First a size comparison with V6 (ignore the crap in the top right)
SO much of the baffle is just DRIVERRRRRRR...

The absolutely beautiful palladium coated drivers of the Sony DR-Z7. Doesn't look as good as the gold of the DR-M7, but still very pretty
