Hello I'm looking for a software to equalize my headphones
See here:
 
I was auditioning headphones to replace a set of grado sr80 and was having trouble finding something that I could comfortably wear all day (not that the grado checked that box either) and totally fell in love with Koss's 60 ohm driver headphones thanks to their light weight and fun sound signature. I then fell down the rabbit hole of modding them to further improve their sound and comfort, there is a whole community of people designing and making mods for every variation of koss 60 ohm driver. Here are a few of my own DIY projects to improve usability, comfort and to a lesser extent sound.

Have you tried the Koss KPH40?: https://koss.com/products/kph40-utility?variant=46100555268327

To my ears they sound very similar to the PortaPro, but the headband is simpler and I found them more comfortable: https://audiosciencereview.com/foru...ro-review-on-ear-headphone.29137/post-1683557
 
Yes, I have tried the kph40 and I very much like the steel headband it comes with. The first image above is a kph40 band with kph30i drivers attached with 3d printed adapters and yaxi pads. The sliders have also been replaced (the OEM sliders broke) and a 3D printed "suspension band" added to avoid the metal band coming into direct contact with the head. The result is pinnacle comfort for me :)
 
Yeah it's really impossible to beat the KPH40 for comfort it seems. I also have AIAIAI tracks but the movement range on the earcup isn't enough to sit flat on my ears. I have the pictured Sennheiser PX100-II as well as the PX200 which are nice but still get uncomfortable due to the clamp. I have some vintage Sony that are like the KPH40 but the drivers are definitely vintage sounding. I also have the KPH30i but the original headband clamps like crazy.
