How to do a KPH40 > Porta Pro Wireless 2.0 Driver Swap

How’s it going!

First off, I dont even know if this is possible or has already been done but I wanted to ask how to do this.

I love my KPH40’s and wish I could make them more portable so they are easier to take places (folding up to put in case and pocket). I bought a Porta Pro thanks to the prime day (week) sale that I plan to swap out the driver housings with the KPH40 to fix the portability but I’m wondering how far I can go, this is Koss *mods* after all.

So naturally, I wanted to know if it is possible to put the KPH40 drivers/driver assemblies *into* the Porta Pro Wireless’ chassis to use the wireless functionality and do it without sacrificing the great sound quality of the KPH40’s.

How would I go about doing this if it’s possible at all?

Thanks!

Helmet ID/History?

Hello,

I bought this helmet ages ago at, of all places, a lumber yard and its been sitting on a shelf since then.

I have almost no idea what it is other than that its for a very small head, barely fits on mine, and is an Adrian (I think) helmet of some kind with the imprint of a firebomb or tree emblem of some kind that has long since been removed.

I have no clue what time period its from really but it appears to still have its original liner, or at least whats left of it.

Looking for any info on it from people deep in this stuff (helmet lore). I’m an aviation guy myself so I don’t even know where to start with infantry helmet ID outside of ID’ing the pots of the major players.

Anything helps, thanks!
