Time to split up the special’s page into two so one for headphones and another one for electronics. Here I’ll list my used electrostatic headphones, either they were a part of my personal collection or were a part of some lot I bought so I refurbished them before listing. Feel free to contact me at firstname.lastname@example.org if you are interested in any item here. I will reply to every mail so if you haven’t received a reply within 24 hours then feel free to send me another email. Email gets lost all the time or is flagged as spam. All prices in US dollars (USD).
Just a quick note about the used headphones. With all electrostatic phones it is possible that they have developed squealing as debris enters the drivers with age. This is something I actively look for and will put in the description (which most sellers would never do) but I might miss some as it can be so subtle. Most of the time this is a minor issue and only comes into play when nothing is playing or on very quiet passages but it’s something I mention if I come across is. Most of the Stax drivers are glued shut so they can’t be cleaned once this has come up. Also the headphone stands the phones sit on are not included.
I’ve been converting normal bias SR-X Mk3 models over to Pro bias for years now using Pro bias drivers pulled from Gamma units but this is something different, pro bias drivers using the normal bias shells with my own diaphragms. I had bias rings custom cut to my specification and they fit inside the normal bias shell and with some more modding, they are turned into pro bias drivers. The diaphragm is 1.4um and uses my own custom coating and I’ve copied the stock Stax sound but it is not a 100% copy. I made them a bit warmer to suit my tastes better as the stock SR-X mk3 pro can be a bit bright. Then I fit a Stax Wide PC-OCC cable and new earpads to the set to round it all off. So a faithful copy of one of the best Stax headphones ever made. 🙂

King Sound H-03 which I’ve modified and fitted with custom made earpads made to my specs. Stock these sound pretty terrible but the new alcantara/leather hybrid earpads clean up sound a lot and so do the internal mods I did. I had the H-02’s back in the day and I never got them to sound this good. They will also come with the original earpads if the buyer wants them and the original box.

Stax SR-303 in very good condition. The plan was to sacrifice this one to make a Sigma 303 but I found a poor condition 404 with excellent drivers so this one is spared. This is one of the last made which is evident by the silver protection mesh inside the drivers. It has the stock earpads but the foam is all gone. Not a problem in my book so I just cleaned them out and tried them. No noise issues, no imbalance or anything like that.

This is an odd one, it seems to be a SR-Lambda Spirit but it has a new arc with no markings on it. This has clearly gone in to Stax for servicing at some point as the arc is new and so are the earpads and the damping inside the earpads. They do sound lovely and I bought them just because I was curious. I’ve been trying to trim my collection down so these are up for sale.

My second trimming of the headphone collection this year is under way and here is one of my favorite Lambdas, the original normal bias SR-Lambda. I have four of these so some have to go. 🙂 These were always the overlooked part of the Lambda line back in the day until I bought a set and was shocked at how good they were. The SR-Lambda Pro always got all the attention but I found these to be more balanced and even handed, better treble and bass too. This set has been cleaned from head to toe and fitted with new black earpads. The crumbling foam inside the earcups was removed and the damping used there cleaned up.

This is the second SR-Lambda I have for sale. This one is fully stock and with the original earpads. They were in good condition so I left them in place. The foam is long gone but it has no impact on the sound quality. I took this set apart as well to remove the crumbling foam from inside the earcups and cleaned the damping pads. I also remove the silistors inside the earcups as they can cause problems these days.
