Yes, they looks well-made and will be great to see the drivers too.

Produce around 1975-1980, I think.

Oh my. Those are in immaculate condition, AND with paperwork

Very cool. Is there anything interesting in the literature?

I'm thinking of replacing the headband/flattened pads on my pair, but I'll probably end up stuffing foam inside, so it retains it's look.

My K340 has plenty of treble. Perhaps your electrets are not working as well as they should be? Also your pads look a little flat.

Makeover of a pair of vintage headphones:

2010-02-2814-33-35089.jpg


Pioneer SE-500 as a base model:
1) replaced single sided cable (with terrible oxidation) with a silver plated oxygen free copper stranded cable sleeved in PVC in a 4 conductor round litz dual entry cable
2) removed original headband and replaced with a Beyerdynamic leatherette headband
3) removed the piezoelectric drivers (though interesting technically, they sounded poopy) with SFI ribbon tweeters (120 ohm)
4) added additional damping to remove midbass resonance and to extend treble extension
5) removed fabric screen from the back of the cups (unnecessary IMO, but looks better now)

I think that they sound good, but probably because of the effort I put into them

. I've since given them to my younger brother and he thinks they sound pretty good as well

I don't think you'll ever see them on the street, but they have that distinct 1970's kitschy/classy style.

Hello all,
I picked these up recently and haven't been able to find any info on them, but I'm thinking about working on them a bit (there's some echo/distortion across the (reversed) left/right channels), and picking up some kind of replacement pads as the current ones smell a bit smokey. They sound like they could be half decent with a bit of love.
