These wouldn't be considered audiophile quality by today's standards but they started it all. There were other Electrostatic headphones around during the 60's and 70's but Stax is the only ones that are still around today.
 
The original Lamaba earspeaker released in 1979, a great headphone even by today's standards!
 
It wasn't until the 1990's that other companies finally caught up and surpass Stax. But only in the very high end.
 
Now you don't need Stax to have great sound anymore, but many still prefer the original audiophile headphones since nothing else sounds like them.

Not audiophile quality but an amazing collector item! Bragging rights! And yes the sounds the 70s or 80s and early 90s produce was pretty unique.

Lots of legendary headphones, like the Sony mdr-r10 that was considered a holy grail for awhile there.

I am enjoying this series btw. Keep it up!


Its the most talked about and has the biggest love affair worldwide. I'm more after stuff that people forgotten and need to know. And never knew about.

  Hi,
 
The Sony MDR-R10 will actually be my final last post in this series! Why because the MDR R10 approval rating is near perfection with low disapproval rating. Its the most talked about and has the biggest love affair worldwide. I'm more after stuff that people forgotten and need to know. And never knew about.
 
Thanks 

 
Really? How many have actually heard it? It was pretty rare back in the old days, it must be even rarer now.

  Also this is another reason I might never do an article on the Sony. There's pretty much no reason once you see this!!!!!

Thanks 

 
Nice review! BTW, I have heard the MDR-R10. It was a long time ago, so I don't remember the sound to be honest, I just remember that they were super comfortable. LOL.

They very similar.They are like time machine ,you put them on your head and you go back to the sixties :)
Sound is not very good compare to Lambdas.They have poor stereophony compare to later Stax so it is time machine,part of a histry,colectors item more then for listening.
So many years since the was born and drivers still work well.
