OK these are just beyond sick! Wireless Bluetooth version of my Resto-modded Koss DJ Headphones!
And they’re switchable from Bluetooth to wired connection! A removable cord is realized with a mini-DIN plug. The cord features a holder for the 1/4″ adapter, and a section of bungee-cord strain relief.
Folks, it doesn’t get more 70s than this!
And they sound better than most modern headphones.
Get them while you can! A beige pair of Pro4/A is coming soon too
I’m reaching absurd levels of over-the-top with these Koss DJ headphones! LOL

OK, these are just too gorgeous!
These beauties are Koss Pro/5LC, and are basically the same headphone as the Koss Pro/4AA that I resto-modded in a previous blog post.
The Pro5/LC has a squared-off earcup instead of domed, and features level-control dials along the bottom edge. (Thus Pro5/LC) I removed the dials and filled the gap with epoxy putty and painted it to match. It’s hardly visible.
Yes, they are for sale, and yes they are expensive! It’s a entire day’s work for me to build a set of these headphones. I sell the beige Pro4/AA for $550, and these are $600, because of their rarity, and the extra work involved filling the gap left by the removal of the level controls. They come with lifetime earpad replacement for $20, and a $50 flat-rate repair warranty.)
Why don’t all DJ headphones do this? I’ve installed a locking mechanism to the headband on my Koss resto-modded DJ headphones! No more fumbling to adjust while I’m playing. If you buy a set from me, they will now come with this feature.
Did you know that stereo headphones for personal music listening, were invented right here in Wisconsin? In 1958, John C. Koss, and engineer Martin Lange, Jr. invented the Koss SP/3, as an accessory to a new stereo portable record player. The headphones were a smash hit, and proved more popular than the record player!

Hi Chris! I bought some refurb stuff from you a couple years ago to rebuild an old 555. I got the input board and the soft start power supply. I just wanted to circle back and tell you how it’s working out. I recently was able to get an Audio Precision System 2 analyzer in trade for some work. I have been learning how to use it and thought I’d run the 555 on it!
This is just a small sample – looking amazing:
The frequency response is very flat. And the THD+N is really low even at very low volume. THD is even across the frequency range.
Nice stuff, Chris! You gave me a lot of help and it’s sort of kicked off a hobby for me. I’ve been fixing up old gear in my spare time and have had a lot of fun with it.

My buddy Tim has a Lenco turntable with a synchronous AC motor, and paid me to build this “Nigel’s Speed Controller”. Basically, it’s an AC power re-generator that produces a much cleaner AC power supply. A low-distortion sine wave generator feeds an audio amplifier, that feeds a transformer that steps up the voltage to 110-120VAC.
