Thanks for the pix!

I've only ever had an HP3, and I passed that on a while ago, so I can't really comment on yamaha similarities... but I don't remember any headphone I've had being damped like this one.

The driver sits inside a ring of thick black felt which is indeed around the vents.

Was the driver held in place only with the foam holding it to the baffle? ( besides the friction from the felt ring ) or does the cup fit there hold it in place when the curved clamps in the picture get seated back down?

It looks like only the felt holds the driver in place. It's a VERY snug fit.

Earside the driver sits against the thin rubber ring to form a seal, so it's kind of important to not push the driver on the ear-side otherwise the seal breaks and bass drops. (obviously I don't mean it 'drops the bass'... you know what I mean)

The 'ex' foam seems to only be there to provide basic damping and more likely prevent sound reflections from the inside of the cup.

 

So yeah... one could say the driver is actually not held down at all. Because in truth, it isn't.

Dual headphones also have drivers suspended using just foam.

and TDS-16 small versions:)

The U70 driver is also held in place by felt.

Actually I think the PMB8 and U70 share the same (or very similar) driver. 

Which is weird because they have quite different specs.

 

Anyway I was more referring to it being the first time I've seen a ring of felt around the driver edge for damping, not a driver being held by felt/foam.
