Used headphones

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 spritzer@mjolnir-audio.com 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.

A Stax SR-L700 Mk1 with upgraded Mk2 forks in very good condition.  The Mk2 forks are a welcome update for these and many prefer the Mk1 to the newer Mk2.  No original box with this one but they will be very well packaged.

Here is a stock SR-Sigma Pro’s with the rather rare late drivers.  This makes this the best sounding stock Sigma Stax ever made, more full sounding than the early Sigma Pro’s and close to the 404’s in performance.

This set came here in a rather sorry state, the arc had suffered heat damage and it affected the top of one earcup as can be seen in the pictures.  The headband was also trashed and so was the cable.  So I replaced the arc, headpad and cable with parts I had in stock.  Now they look good aside from that heat damage on top of the earcup and some paint peeling off the front facing grill.  Functionally they are great though and sound excellent.

Here is a Lambda Nova Classic that was recently refurbished by Stax in Japan.  Truly the greatest range of Lambda’s ever made and the Classic is 99% of the Signature sound for a lot less money.   Very balanced sound signature and slightly on the warm side.  These are becoming very scarce as they close in on being 30 years old.

Price: 550$ plus shipping

This is a clean and tidy set of SR-303’s.  The foam inside the earcups and covering the drivers had degraded so I cleaned it out but otherwise they look great and sound even better.  Comes with the original box as well

Price: 550$ plus shipping

Here is a rather nice SR-307 which comes with the original box.  I replaced the earpads with new unit so it really is as good as new.  Truly one of the last great Stax units with a very nice and balanced sound.

Price:  550$ plus shipping

A really rather nice set of SR-303’s which come with the original box.  The earpads are nearly new and the headpad is in very nice condition so these were just too nice to be turned into a Sigma/303.  These are really the golden age for Stax, balanced and extended sound with plenty of presence.

Price:  550$ plus shipping

Here is a set of Lambda Nova Classic’s which I refurbished.  These suffered from what all Lambda Nova’s, the drivers were loose from the baffle and the earpads and headpad were trash.  The drivers were reglued and reinforced and the earpads and headpad were replaced.  The Lambda Nova series is getting thin on the ground now as they are almost 30 years old and Stax used some subpar materials on them so they don’t hold up as well as the older series.  Still, they are from the age of the SR-Omega so they share that warm and lush sound sound.  Highly recommended.

Price: 600$ plus shipping

This is a SR-X Mk3’s in pretty good condition.  The drivers are perfectly balanced and charge quickly and I’ve fitted them with some deep real leather earpads to make them more comfortable.  One of the best normal bias Stax units ever made.

Price: 280$ plus shipping

Here is a stock Stax SR-404 in good condition.  This is the second version of these which means it was fitted with earpads that had foam inserts which have crumbled away.  In every other way they look good and sound great.  Warmer and more forgiving than the modern Stax stuff but with some body to it.

Price: 400$ plus shipping

Second set of SR-404’s for sale.  Very nice condition and with the latest earpads.  Truly one of the best electrostatics out there at a sane price.

Price: 450$ plus shipping

Stax SR-50 electret unit which is pretty rare and only one of two closed electrostatics that actually work ok.  This set sounds great and look good for something made in the late 70’s.

Price: 260$ plus shipping

Stax SR-80 Pro electrets.  These were called the mini Lambdas back in the day and do sound really nice.  This set is in pretty good condition and they make for great test sets since you don’t need a bias supply for them.

Price: 210$ plus shipping

Here is a super rare one, the Stax SR-X mk1 aka. the first Stax to ever have a mesh driver.  This one was only out for a couple of years 1970-1972 when it was replaced with the Mk2.  That was also short lived as the Mk3 took over in 1975.  This one is up there with the SR-1 in terms of rarity but I’m trying to cut down my collection so it must go.  Comes with new SR-X earpads and is in very good condition for a set that’s this old.

Price:  350$ plus shipping

Here below is my entire reference collection of the Stax SR series, from SR-1 and through the SR-5.  Some of these I’ve had for close to 20 years but I never use them and I’m a bit over mindlessly collecting stuff so I’m listing them for sale.  Some of these are worth a lot of money and are very, very rare  so the prices will reflect that. They have all been cleaned, kept in a dust free cabinet and fitted with new earpads.  The old, rare ones I never used aside from plugging them in when I got them due to the rarity and collector nature of them.

This looks like a last version SR-1.  The inside of the earcups are white and not red/blue and this one is close to the SR-2 build.

Price: 1100$ plus shipping

SR-3 in perfect condition. This was the first of the “common” Stax headphones so these are relatively easy to find though not in this condition.  Great sounding headphones with excellent midrange but the top and bottom end extension is pretty limited compared to more modern units.  Still must have been quite special back in 1968

Price: 450$ plus shipping

SR-3New (aka the SR-4) in excellent condition. They look like new and just look at that cable… they never look like that these days.

Price: 400$ plus shipping
