New Head-Fier
Hello everyone.
'Seems to me like it really is kind of byzarre trying to compare fully open headphones like Portapro and fully closed headphones like Pro4AA. Like comparing a drone and a helicopter. Thus, in the idea of melting these two together, I am planning to mod Koss Pro4aa "Frankensteen way" (or "lemon incest" way) by putting PortaPro drivers inside. I hope it will not be too hard adjusting the famous piece of blue plastic inside the old black plate.
More to come in 2019.
To be continued...
While waiting, see this other mod thread please:
