I'll have to take some pictures. It just has a very thin layer of foam, so thin that it provides no padding at all. I'm afraid if I add padding, I'll decrease the bass. What ever I end up using for ear pads will need to be very thin.

The leather is very thin, but I'll wait for your pictures before I say more.

Having taken the HOK80 apart, I noticed that instead of air tight paper tape on the back grilles as the Grundig has, the HOK has a plastic disc, and a net (!).

I think even the traditional Yamaha pads might be a little too thick. I should get to working on them one day this week.

The HOK80 was easy to take apart, following the instruction from ericj, and out fell the annoying ring dingus.

As for sealing them - there's really no way to seal between the cup and the baffle, but you should seal the driver to the baffle and then apply vinyl tape over the holes in the baffle - or stuff them with poster tak.

That gap around the edge of the earcup, well, best you can do is stuff the edge of the earpad collar in there, probably. But it's not a big deal.

It looks like these could be difficult to seal properly.

And you cannot reassemble the headphone without that annoying ring dingus. But i believe that the careful application of tacky substances can make reassembly much easier.

Yes - a plastic disc that looks like it was recycled from flash and grind in a pan on the stove, then smeared out on a table with a pallet knife and cut out with scissors.

In other news, behold the power of RelentlessSearch:

I know you posted that picture before but I couldn't find it and I was too lazy to use ludoo's search. I'm amazed that doesn't kill the bass, but it does eliminate the pain.

Fortunately, I wouldn't have bid against you anyway since I already own one.

I even gained a bit of bass impact with this mod

Per agreements made yesterday - when we feared that other search ninjitsu lurking in the darkness may drive the price to ten times what we ultimately paid - two are going to F2D.

It's good to have two on hand when developing a damping strategy, but i won't have a need for two after I've gotten somewhere with the mod. So, ludoo, you have 1st dibs on my 2nd pair. And i do kinda want a YH-50(a,s).

Wow thanks a lot, I guess we have a deal then (plus cash/shipping/whatever you feel the T30 are worth in respect to the HP50A). The 50A are recabled with Mogami, but I still have the original mono cable and a couple HP3 ones if you want to bring them back to stock. The pads are great, they were NIB when I got them, the box is not mint but in nice condition. It will also be the occasion to send you some felts so we have a common ground for modding.

Four of them!? Amazing.


I will follow your re-assembly instructions carefully for the HOK. But first I will seal them up good.

As for the bass issue, there are two contradictory theories. One says closer=more bass, the other more distance = more bass extension.

It is pretty strange we're all paying over the odds for old orthos when there's brand spankin new ones filling the shelves of every pro music shop on the planet. Personally I blame wualta for trashing them early on in this thread and putting us all off

However, with their latest tweaks and new pads it might well be worth a look as soon as I can dig up a spare $65 or so. At the very least I'll have another driver to dismember.
Yeah, that's exactly why I want to try the new stuff out for myself. The T50RP is the first truly new headphone I have ever bought, actually. And I bought it for a price under the going price of a lot of the older orthos today. And damn, the sale is over at Musician's Friend. I guess I'm not going to also pick up a T40RP MkII for cheap.

Of course, if you have something like RelentlessSearch, you may still save money buying vintage over new.

Eric.... Holy crap man, amazing find/deal! Congrats.

DAC, I don't think there is one true way. Both work. I just re-jigged my T40 pad setup on a niggling doubt and wham! More, deeper, better bass using the trusty old weatherstrip. Thick stuff this time. It really is great stuff. I previously had another earpad inside but the thick strip works even better.

Oh, in case you were wondering, it's to make them supra-circum for both bass and comfort. Sounds awesome.
