    Does anyone have any info on the Koss XTR-9's?

    I've only been able to find some auction listings on estate sites and on eBay, but I haven't really seen any information besides that. Even when looking at Koss' own history page, there doesn't seem to be a mention of the headphone at all. Maybe I'm not looking hard enough, but does anyone have...

    Koss K-500 vintage headphones

    After all, the company Koss during the leadership of its founder John Koss was truly great, and then the optimizers came and it turned out what happened. Otherwise, how to explain the fact that the company could produce small-scale batches of headphones for "human testing". The case in the...

    Koss KSC75 vs Porta Pro?

    I've been looking at these two headphones as the best "beginner" audiophile headphones because of the low price. Does anyone know how they differ in sound? From what I've heard so far, the Porta Pros sound relatively warmer.

    Koss HV/X replacement pads?

    Koss finally stopped selling replacement pads for my HV/X. The pads were great except that they literally disintegrate after a few years. The original pads came with adhesive on them which stuck to the smooth plastic of the headphone. Does anyone know what pads might fit this headphone?

    Electrostatic headphones - membrane coating loss?

    HI Folks, Not too long ago, I bought a near-mint, still boxed pair of early 70s, Koss ESP-9 electrostatic headphones. Obviously old, but in good cosmetic shape & seems barely used. After several weeks I found the time to hook them up. I wired the E-9 energizer to the back of my Kenwood 700M...

    KOSS KSC75 vs Soundmagic E10C

    I am in a need for a new daily driver after I lost my E10Cs a few days ago and I've heard quite a bit of good things about the Koss but how do they compare to the E10Cs. I liked them well enough for outside stuff because of the decent sound and reasonable price. The Koss cost less and supposedly...

    For Halloween: Re-animating the JVC HA-RX330

    So, for Halloween, I decided to do a small audio project - to BRING the DEAD back to LIFE! Perhaps worse than dead, take a dull, lifeless sounding headphone and turn it into a real killer... The Victim: I found a clearance JVC HA-RX330 at my local Fry's for the undead price of $4.99! I snatched...

    KSC75 Over the Ear Project

    The project was initially inspired when I ran across the StratoKOSSter thread by accident while troubleshooting a problem with my Sony MDR V6. I read the thread and was pretty encouraged by the results claimed. Since I am somewhat handy I thought I would come up with my own design. Here is a...

    Replacement Pads for Koss K-6

    I found a pair of Koss K-6 at an antiques store and impulse bought them. Now I'm trying to refurbish them. There is a crackle when the cable is moved and they only work when the cable is in one particular position, so I will be either redoing the connections or the entire wire, but I digress...

    Koss PortaPro's or Sony MDR-XB550AP?

    They cost almost the same and I just wonder which one of them would you buy if you had my needs? So I'm looking for a pair of on ear headphones that I'll be able to use mainly at the gym but sometimes at the buss too. My priorities are: sound quality > Isolation > Comfort > Durability > sound...

    Is there a way to still buy AKG K26? Or similar recommendations? (watch Pontypool before reading topic!)

    Hi everyone! I am a huge Koss Porta pro fan and I use it as my main driver with fiio e10k. PC use almost exclusively. I like the adjustment mechanism, build, how light it is, comfort and of course sound quality(I like warm, bassy enjoyable sound). I would like a headphone quite similar but...

    Koss TNT/88. . .My first pair of headphones

    Hello all,   So today I finally got on it to hunt down my first pair of headphones I ever used, the Koss TNT/88.  I have absolutely no earthly clue about them, as they are basically as old as me from what little bit I did find on them.  I found an article talking about the "new Koss TNT...
