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!
