Hi all. it's been a while since i posted anything here. I was going to post the headphone mod i made on my PortaPro. in 2014 i bought a headphone from Lithuania on ebay for 10 usd a Vintage Soviet Headphones ToH-2 (Tone-2) It made me think i could use the headband and put the drivers in, and it does fit it looks like Sennheiser 414! as you can see i put on the Koss logo plates on as well sounds great and it sits firmer on my head than the original PortaPro headphone band
