If you sell Series 2 drivers, I would be interested!

Ok, good. I was told that the series 2 was only black and that confused me since the black and white drivers look the same.

  This is the same series driver and headphones that I have. The left one is held on by the plastic, while the right driver is held on by 4 screws.

Strange. My second series driver is all white and has 4 tabs for mounting it to the Pro 4aaa. Sadly, Now my budget is extremely low, so it's unlikely that I will come across a first or second series driver to replace my broken second series driver.

Darn! I didn't see the post until today! Thanks for trying to help me, I really appreciate it.

I sadly only own one pro4aaa. But hopefully I can find a driver soon so I can put them to use. I also need to rewire mine. I might make the cord removable for easier storage for transportation. Then if it needed another cable replacement, it would be easy!

I have noticed the plastic pieces connecting the yolks to the ear cups are slightly different on some Pro4aaas. If you look at your pictrure it that last post and one before, you can see a difference.

Also, do you know where I can get the black padded head strap? Pro4aaa models are rare, so it's not easy to get one.

It got sold :( Oh well, I'll probably find one eventually. Is there any was to see what series driver they have without actually opening them up?

My driver just gave up on me for some reason, and it wasnt actually me who pulled the driver out, so when it got removed, the diaphragm got ripped off rendering the whole driver useless. It's really easy to break the drivers too. Oh, and Koss said that they cannot repair mine because they don't...

Wow, that is awesome! Now I can look for a pair to fix my Pro4aaas! I have the series 2 driver, but have never seen the series 4 driver. Thanks so much! Finally, I find out that they are the same!

Thanks for the reply! So does that mean that the Pro4aa drivers are the same as the Pro4aaa drivers? I've seen lots of Pro4aas that I could have got, but I thought they had different drivers.

I've heard that the 4AAAT isn't so great. Also, I've been looking on eBay for a while, but when they pop up, people always sell them as auctions and I can't seem to get my hands on a set! :(

Hmmm. Too bad these things are so old and basically non-existent anymore... If I had the money, I would probably try buying a new Pro 4AA or AAAT, but I really don't have much money to spend. Too bad there isn't some sort of replacement driver I could buy. Since I've been checking eBay and...

Thanks for the reply! Unfortunately, I have already emailed Koss, and was told that my product was no longer supported by the warranty(I saw quite a few threads about people doing that and their's being covered by the warranty). Then again, even if it was, mine has been opened and "modified" I...

Hi, I have a pair of old(not Pro 4AAAT) Koss headphones that I would really appreciate help on finding a driver for. I am for sure that it is the driver and it is the right driver. If you guys could help, that would be awesome! So, if you guys could assist me in finding a driver I would be...
