If anyone is curious, this is what the guts of the Pro 80 looks like.
What exactly have I done this time?
Well firstly, I decided to replace that gawd awful wire (if you can call it that) that connects the right driver to the distributor on the left. The original cable is like 30-32AWG tiny, TINY, IEM style cable. I replaced it with 26AWG solid core silver plated copper wire, 2 per contact (4 in total), with a simple twist braid since solid copper doesn't tend to look good with a round brain for some reason.
As well as, I upgraded the 3.5mm chassis socket to something with more grip on the patch cable.
And, pièce de résistance, are the ports. I've been thinking quite a while, a couple of months now, on how I could possibly improve the Pro 80s without damaging permanently any part of the headphone. I've seen people poke holes in the paper baffle, and modify the plastic baffle, thing that I wouldn't be willing to do. So I started thinking, "why not use a tried and true method?", the bass port holes. Looking inside the cup, I found a good non-evasive location for a port hole (see picture; anywhere dead centre of that plastic rings is a safe place). A port hole was kind of a no brainer really, if it doesn't work you can plug it; a lot of headphone companies already do this like ZMF. I started with a 1mm hole and worked my way up to a 2.5mm hole which feels like the sweet spot. I used SineGen to sweep the frequencies every time I made a change. I was tedious and time consuming, but so worth it in the end. The change in sound is a punchier bass response, which is a little bit more controlled, with a noticeably more low bass presence. Most importantly, it's a mod that all of us can do quite easily without spending any money at all. You could also make the holes bigger to increase the bass response even more. Additionally you can make multiple holes and get some rubber plugs and make the bass response adjustable. Do what you will, as I say.
