Thanks to Martin (Dillen) I picked these headphones up on a Danish website.

They sound absolutely superb - on a par with my Grado's in fact!  However, I know absolutely nothing about them.

I'll start with the casing of the 'cans' on which is written 'VibroCard' - Bang & Olufsen Technology.  

The coating on the earpads is very similar to the covering on the U70's, and indeed it's beginning to peel off like they do since i've started using them regularly.  The cable which goes from the headphones and terminates in a 3.5mm jack also has 'Audio Technica - ARTLINK - Titan' printed on it.

So.. help me out.. what's the history of these great sounding headphones?!  I'm intrigued..

...

and finally..

 - possibly from the Medical Division???

The only references I can find seem to be regarding audio diagnosis of cardiolgical problems using some sort of audio analyser...maybe the headphones were supplied with that?

Medicom was my initial thought due to the colour.  Functional as opposed to pretty, so suited to more of a working environment..

They are very well insulated from outside noise - and the clarity of them is amazing, really.

I'm sure someone will have seen these before... Surely!

While I can offer nothing by way of their history, may I suggest there is one word to describe them:  groovy!
