Latest news in the world of fake Koss Porta Pros?

post #1 of 3
Thread Starter 

Today I've unwrapped a pair of Koss Porta Pro Black Beauty which came from ebay which were sold as damaged packaging for the not stupidly cheap price of £22 (about $35)  I'm aware that ebay has a bad rep for Porta Pros so at the first opportunity I unpacked and examined them, then put them on and came online to check how to detect fakes.

 

I last heard a pair years ago but they were modded and I had a different DAP so my memory isn't reliable for the sound and I don't want to mod these until I'm sure they're genuine or I'll not get my money back.  My last pair had a right angle jack and black non-sleeved cable, the new ones have a black and white sleeved cable and a 60 degree plug (not right angle but nowhere near straight...)

 

So far I've gathered that these are good things:

 

No noticeable smell

All pads are black

Has the bin sticker near the jack

Sounds pretty good (no burn in, no modsthey can't be great...)

Comfort zone works

All fonts and pics look crisp and perfectly aligned

Has little Koss on earpieces just below the headband

 

And these that may be bad:

 

Sides are numbered 3 and 4 (but the background is smooth, so this is ok?)

No 1/4 adaptor

Case kinda looks like the fake one where the string exits, and the logo background isn't smooth it has feint vertical stripes

 

 

They came in packaging that's nothing like any pic I've seen in the fake guides (the only pic I can find is on head-fi - mine looks like this but it's black) but as all the guides are years old so it may have changed.  The drivers measure 56 ohms on my meter, so pretty close to expected and it's a cheap meter.

 

Is there anywhere with an up to date list of things to check?  Has anyone even seen/heard of a fake pair with a black headband?

 

Thanks for any help and I hope your presents are less worrisome than mine! :happy_face1:

Thanks, from the look of those mine are genuine - the corner bit is slightly rounded and doesn't fit perfectly as in the first genuine pic, and the bottom surround is one smooth and quite wide band not angular as in the second fake one. 

 

Seems I can get on and mod them :etysmile:
