This weekend I've bought a Technics EAH-500 - they looks the same except the Technics name on the headband. Pretty nice sound I'd say - the drivers are pretty big too. I put some fotos if I find time.

Are these dynamics?

 

[khirst]

Yep, the're dynamic - the drivers have some triangular symbol on, are made in Japan and are 125 Ohms. Other numbers on them are EAS-5P07A and K922. Magnet size is 33mm, driver size 51mm.

I've founs some new infos:
They were mentioned in Popular Science from November 1979 along w few others:
Popular Science - Google Bücher
Also the productions year is about 1979.

In this article we found a little table where stays:
They weren't expensive - 40$ at the time - less then AKG's K141
They're open type.
125 Ohms
Sensitivity 0,6V/100dB
Distortion 0,5%
Weight 8,2 Oz

just received an eah-520

 

[JeckyllAndHyde]

any good? They are duo-cone (whatever that means)

 

[ourfpshero]

not much bass, nice besides that. i need to find some foam earpads

[JeckyllAndHyde]

Thats interesting - EAH-500's bass is the best thing about them - its punchy and very low ( thanks to huge driver diameter, I guess)

I've made a quick comparision between EAH500 and my Revox (DT880). In terms of details and soundstage Revox are ahead, BUT: in terms of bass depth and impact the EAH500 are noticeably better!

I tested it on Chemical Brothers "Surrender" and Björk tracks.

spent some time with the eah-520

sound is decent, bass and mids have good texture, highs are just ok. smallish soundstage. compared to the pioneer portables of the day (se-2, 4, and 6) i give the edge to the pioneers, especially in the bass and comfort. mids and mid highs belong to the panasonic

Some better photos

Mine arrived, boxed and like new. Initial sound impressions are not great with a lack of detail and muddy bass. The original warranty is still there and is dated in 1980.
 
                    
 
 

 

 
 
EDIT - I am getting the bass now, rocking!

I'm reviving this old thread because this is the best info on these headphones on the entire web.
I got interested in the vintage headphones and EAH500 caught my attention as it's listed on the 416 headphone museum list and there was a recent cheap ebay listing that I lost as I was trying to enter last minute from my cell phone and the connection was too slow!
 
My question is RE: the frequency response on the band. Looks incredibly flat, but not sure of the scale on the dB. Is this within 3 dB or more like 10 dB?
How about sensitivity. Is Ipod good enough for those?
I'm personally using Sony MDR-V6 and think they are reasonably flat and sound great for my (non-audiophile) listening. Is this going to be an upgrade from Sony?
I like Sony for deep bass, high sensitivity (anything can drive them), sound isolation, and comfort.
The only things I don't like about Sony the trebles are very sharp (peaky near 10kHz) and roll over way before 15 kHz:
