I am the original owner of these Stax Lambda Earspeakers offered for sale. These have been stored for several years but I have used them recently with the Stax SRD-X (that I also have for sale) and are still sounding great. PLEASE NOTE: These are the NORMAL BIAS versions and will not work with Pro connectors.
As you can see from the photos the inner foam is gone however you can get replacements from Stax. Please note that the screen on one driver has been indented and is touching the film. I have overlaid a red arrow to show where is is. Perhaps due to its placement, I have not heard any effects of this. Other than this you can see they are in very could condition and the pads are in great shape. Even the rear dampening foam is intact. While these are obviously being sold as used and AS-IS, I do guarantee they will be working as described upon arrival. I accept PayPal or cash for local pickup in the San Francisco Bay Area. I will pay the PayPal fee and you will pay insured shipping of your choice. I will pack these very carefully and ship them within one business day of cleared payment. I am giving head-fiers a first shot before I post it on eBay. You can check my feedback there as Marks-sf.
