Look at all the Fostexen... http://www.youtube.com/watch?v=7bRJLkNqNXI
Those are T20v1's correct? (and I think a K240M sneaks in there)
Lots of Fostexen, current and vintage. I can't tell if some are T20v1 and/or T10.
What a cast of performers in this video! Thanks for the link.
I first postulated that this was an ortho back in late 2008. And have been searching for it ever since. It seems to be the sole headphone of high-end German manufacturer Canton, which led me to believe they would have made an effort with it. As many of you know I searched high and low and dug out many orthos, but this one always eluded me, it even got to the point I wondered if it was vaporware, as I couldnt even find evidence of its existence anywhere past the brochures. Finally after 4.5 years of searching I managed to find one! one of the trickiest cans for me to find. And my searching from way back then proved positive; this is definitely orthodynamic. Wenche Myhre didnt reply to me about them :p.
The pair I found had the pleather completely gone from the pads to reveal bright white cotton below (also the previous owner seems to have damaged one of the headband sliders and done a diy repair on it).
The peeled pads suggested a PMB oem, but the style was quite unique. I replaced the earpads with some generic ebay ones to get an idea of the sound. It is quite an inneficient phone, this may be due to the damping.
I couldnt yet figure how to open them up fully. just peel away the baffle cloth to take a peek at the driver. (Seen below with the replacement pads)
The specs rate the driver at 200 Ohm, which seems high. Taking a peek under the baffle cloth suggests a pmb-esque driver, but further inspection reveals that it is actually a unique driver.
It has a opened pin in the centre, a little like some pmb's may. The magnet holes are smaller, and more in number than PMB. And are all allined in rows like Yamahas, unlike PMB's which are always concentric. (see pmb examples: http://cdn.head-fi.org/6/6d/6dba5320_PMBdriver2.jpeg and http://cdn.head-fi.org/0/06/06c783af_IMG_5967.JPG). The shots below also show the original Canton pads.
What was v.interesting is the baffle side donut damping layer. The frame is light and comfy. There seems to have been a lot of attention to detail and effort to make a headphone that works and sounds good.
Onto the sound. With the aftermarket pads on (whcih have pleather), the sound is id say right on or slighty above the equilibrium point (of damping). It seems to have a neutral sweet sound reminiscent of pmb, but well rounded and defined throughout. Very clear. Id say its nice from bottom to top. But just lacking slightly in the deep bass amplitude, but deep bass is there. It definately would have lived up to its claims back then of a stat-dynamic bridge.
I cant figure out how to open it, and dont want to be too rough since its so rare. No screws visible on the baffle. It doesnt seem to turn open. Im guessing possibly there is a screw behind the badge, but unsure. Would like to see whats inside the cups and a better view of this unique driver.
A very interesting can that was the only can in it's range :).
*shakes head and slaps myself in the face * Am I dreaming ? How incredible is that!!!!!
Thanks for the post Kabeer. I was racking my brain for weeks trying to guess.
So...how to open it. Unless there's a screw under the badge I would guess it might be a slip-fit with tabs. But if that were the case you'd expects to see some small slots to help pry the tabs.
Just wait a few weeks until i find one also then I will do the damage to mine :)
How much pivot do the cups have. Is it just up and down swivel?
And that is what roughly, a 55mm driver?
Good luck on the search ;).
Pivot: pivots fully, like 360 degrees. not a huge amoutn, but enough do any ear angle.
The opening area i photo'd is 50-ish mm, so the driver is likely 55mm yes.
Many things to be added to the wiki (havent had much time), many things other people on here should add as well ;) , c'mon people.
