What makes some eartips so expensive, they can't cost much to produce? And why are most sold in packs of three different sizes? I don't know anyone with three sets of different sized ears. Am I supposed to keep one set and throw the other two away?

I've tried out nine variations which can't all be called ksc75's. These are: Standard Ksc ..with Kramer mod ... with grill mod. Rewired with silver plated upgrade cable Standard...with Kramer mod...with grill mod. Porta Pro drivers with Ksc earclips standard...with Kramer mod....with grill...

Thanks for your kind offer Willbur, but I already have three sets of KSC 75's all with different mods and another pair with porta pro drivers . I am still trying to find the "perfect " solution

I think they're a lot cheaper in the U.S. compared to U.K

Yep that's them! Yes although the KSC 35's are black, I think they have the same driver as the Porta Pro. I have tried fitting the Porta Pro speakers into the KSC 75 clips, and this is my favourite combination. The problem is you can't seem to buy the clips separately, so you have to...

Has anyone tried the replacement Porta Pro speakers available on eBay? They look okay, and if they sound the same it could be a cheap way to make a pair of KSC 35's

Got up early ready for the 1More crystals....waste of time..... they couldn't be added to cart!

It's available on EBay under " New audio silver plated cable for Koss porta Pro headphones"

These are very good earphones. They do need different tips to the ones supplied to get the best out of them

Recabling the Koss is straightforward because they are easy to disassemble and not too fiddly to work with. They would be the ideal project for someone attempting their first recable. The silver cable really opens out the sound, improving clarity and tightening the bass. They also respond well...

recable with the new audio upgrade silver plated cable available on ebay

I guess it's hard for reviewers not to let their preferences sway their opinions

No...I just used standard cable from a broken set of earphones. I have tried experimenting in the past with high grade cable and to be honest have found the results, considering effort and cost, largely disappointing. Which is strange considering the difference speaker cable can make.

My SHE3800 came with a J cable which I put up with for a couple of days before I re-cabled. They sound okay, but when compared to the TY-HI Z there seems to be a curious bloating to the mids, and a lack of general lack of air and openness. In fact I find the TY preferable in every way

The she3800 doesn't have controls, but I believe there is a version that does. It is more expensive.
