Koss Grado Pro

Hope you like my revamped Koss Porta Pro speakers.
Putting on big Grado pads on Koss KPH30’s is a well known modification among enthousiasts.
But this is for the Koss KSC75/KSC35/KTXPRO1 and uses a double Parts Express head band and a 3d printed insert to keep the speakers nearly centred and to spread the pressure the double bladed head band provides. That pressure is necessary for the rims of the pads to form the contours of your face.
The boost in sound is amazing.
On request, I can make you a pair.
Just let me know.

Nice. I want to do the same with my porta pros. Can you share the 3d model, please?

[@Jansen-Hessels]

The 3d model is mot available for legal reasons as I am in the middle of negotiations with investors. Only a complete assembled set can be arranged. This will be with mmcx 3d domes, yaxi pads and earhooks or parts express headbaand, audio jack, lightnig or usb-c cable.

Podrías mostrar cómo se hace?

[@Jansen-Hessels]

All you need is two parts-express headbands. Take all 4 stems of, Take the two steel strips and stack them on top of each other. Then push the double band back into the stem. Takes some trial and error, but there is just enough room to fit two layers of steel strips like fitting just a single one. The center fitting for the speakers is 3d printed. That is the best way. But speakers with Yaxi pads will also fit well inside the Grado pads. As I am going to sell this “Koss Porta Grado” modifications I can not disclose all details. Drop me a mail at [e-mail] if you want to learn more about buying a ready to use set. For Porta Pro speakers I can offer white,black,red or blue speakers with MMCX, spreaker fittings and Grado pads. Enjoy

@@douglascardenascabrera6843 Thanks. I love these Koss and want to give them the best setting to excel . But there is no “one size fits all” , I do not wear these very much outside. To still enjoy the Koss I take my Koss Banana Pods with me. Yes, Koss Porta Pro speakers with ear hook! kzbin.info5VBfHpHCZPc?feature=share
