> the area’s coating

Doesn't look like there's any coating. To me it looks like simple injection-molded plastic with a metal charging pad.

The water-proof part is the mesh in front of the microphone/speaker, and a seal/gasket where the shells meet so that no water enters the inside volume where it could cause electric shorts.

It‘s not fully clear from the picture - but some adhesives/glues are green. There‘s a possibility that the adhesive that was used to secure and seal the PCBA inside the earphone was leaking next to the charging pad, hence why it‘s visible outside.

Could also be corrosion, hard to tell from the picture.

It's origin is the HD580, which was released in 1993. That's 30 years ago.
The HD580 Jubilee (1995) and HD600 (1996) are small modifications of the HD580, and the HD650 (2003) has slightly less distortion.

It's old - ancient, if you were to apply the same metrics as for e.g. semiconductors.
But (passive) headphones are not semiconductors, and how good a headphone is generally doesn't correlate a lot with how old it is.

The HE1 is very (!) close to the Harman Target (not by coincidence but also not because they wanted to, Sennheiser‘s internal research simply yielded very similar results to Harman‘s).

So I wouldn‘t say the Susvara tried to copy the HE1‘s sound, it just was designed with a similar target in mind (transparent, uncolored sound)

With a load impedance that high you'll mostly be concerned about providing sufficient voltage. Current draw (and hence power) won't be high due to the high load impedance.

It's going to change the magnetic field.
This is - theoretically - predictable of course. Electrodynamics is a well understood field. But some of the parameters will be tricky to find out in your situation (magnetic remanence, for example).

Any number of things could happen, but the most likely outcome is that it's not going to "better" in any quantifiable measure.

Headphones with built-in filters have been around for a decade, maybe more.

Every TWS in-earphone, every wireless headphone has that nowadays.
