The left phone on my portapro has started making some "scratching" sounds sometimes. Mostly on prominent bass. It goes away by itself after a while. The headset is maybe 6 years old, so the receipt is long gone. Koss won't fix it for free without this. Maybe some of you know what the problem could be, and how to fix it by myself?

If I can't fix it I was thinking of buying the ksc75's and putting them on the portapro headband. Not a bad replacement, but if possible I want to try and fix these and save the money...

Check the Koss website, they have a lifetime warranty. Send them in to Koss and they'll send you a new pair, no receipt required.

I e-mailed koss awhile ago about the warranty. They said "Please include: $6.00 for US warranty or $7.00 for Canadian for the return shipping and handling per stereophone (money order, cashier's check, or personal check: payable to Koss Stereophones), a note describing the failure, as well as your contact information: return shipping address, phone number and email." Nothing about needing a receipt. Although this may be only for Canada/US

Sounds like you have some dirt, dust or a hair in the driver. Take off the pads and clean it.

I'll try and clean it first. I have a long history of breaking things, so I have to convince myself it's safe...

On the Koss norwegian homepage it says that the warranty can not be claimed without the original receipt shown. And that the headset should be delivered in the store they were bought! This sounds like bs...

Why should any of this be necessary when there's a lifetime warranty? If I can't fix it, I think I'll try and send them in anyways. Maybe they'll just fix it...

How did it all work out for you?
