By Mike Portables 13/05/2010 The Porta-KSC75Adhisan, a local forum member, showed me his Koss KSC75. It’s a oKSC75 with a Porta-Pro style frame. The frame is a knock-off design of the original PortaPro. Surprisingly, it’s plug-and-play with the KSC75 housing. Rate this post Mike Facebook Previous article“Warm and Detailed”, and More.

If only Koss still makes these clipon phone. It's more neutral as in less bass bloat compared to the PortaPro and the worst of them KSC75. Reply May 14, 2010 MikeThanks for the info, thuantran. Reply May 14, 2010 MikeI guess I forgot to add that the whole point of this mod is that the Portapro clone costs only $5, and that it's a cheap way to get Portapro headband, which works better for some people than the original KSC75 clip. Reply May 14, 2010 EarfoniaThis is what I'm looking for 😀 Thank you!Already pm Adhisan for the place to buy it 🙂 Reply May 15, 2010 MikeYea.. let's make a Headfonia Group Buy for these $5 Portapro frames!

The headband shrinks the soundstage and makes the bass boomier. Leave a Reply Click here to cancel reply.
