By Mike Portables 13/05/2010 The Koss KSC75 Adhisan, a local forum member, showed me his Koss KSC75. It’s an 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 Mike Thanks for the info, thuantran. Reply May 14, 2010 Mike I 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 Earfonia This is what I'm looking for 😀 Thank you! Already pm Adhisan for the place to buy it 🙂 Reply May 15, 2010 Mike Yea.. let's make a Headfonia Group Buy for these $5 Portapro frames! Reply May 15, 2010 Earfonia Count me in, thanks! 😀 Reply May 15, 2010 adhisan very nice photos mike.. 😀 actually i got the porta-frame headphone information from my friend @ indonesian forum kaskus.us audio sub forum.. and after he post it,, the headphone become "most wanted" n little hard to find,, im very lucky to get mine,, the seller where i buy it said that mine is the last stock.. anyway the headband not just changes the way it looks n comfort but also changes the overall sq,, it brings the overall warmness that the stock ksc75 lacks 😀 Reply May 15, 2010 Mike So you got the last copy huh… very suspicious. 🙂 Reply May 15, 2010 Earfonia I hope, with publications like this, the price won't go up 🙁 Reply October 23, 2011 DodgersKings323 I did this too because i preferred the ksc to the PP, but now they are my grandmas portable rig 🙂 Reply February 24, 2014 Nicolas Chupick I tried this at home with a genuine PortaPro frame and a KSC75 and I was unimpressed. The headband shrinks the soundstage and makes the bass boomier. Leave a Reply Click here to cancel reply.
