Sweet!
Btw earlier posts about the TDS-5 , they are visually close to a PMB yes, but apparently not the same, pleated versus non pleated, tensioned vs non-tensioned something to that effect.
The info is buried deep in the ortho thread from overseas users. Didn't bother to save the links.

Elega DR-206C driver
Dynamic driver, slightly larger than a standar 40mm driver. Material is teflon (?) But for some reason, the middle is paper?

Interesting thanks for posting.
You might be able to play around with the hole pattern on the front of the baffle just in front of the driver ( or possibly remove it see what happens ), that'll be what is giving you it's current tuning. Depending on what the driver sounds like without that of course.

Rare Sony MDR-V7 Titanium 40mm ( no do not believe any of the hearsay in here these are Titanium evaporated ).

The hell?? Are you SURE that's an MDR-V7 driver? It's supposed to be a 50mm evaporated sapphire driver. Wrong size AND wrong material seems a bit far fetched... especially when the specs come straight from Sony.

yeah I have had 3 pairs of the things over time.
And know one other person also who has them too. And measured each with a ruler. the misconception has been corrected a couple times in various posts but people believe what they want I guess. Heck I saw that corrected then one or two posts later completely ignored again like it didn't even exist, the oddest thing.
Specs from Sony? Both my box front and a pic of the actual box rear says otherwise.
I have seen other box fronts in photos also, no difference.
Also this is the boxfont here.

See "Titanium Deposition " there at the bottom
The Sony CD777 are evaporated Sapphire but only 40mm, Sony CD999 evaporated Diamond ones are yes 50mm, and it is quite obvious difference right away when looking at them.
Perhaps the V700 had a 50mm.
the V7 baffle itself does not fit and cannot properly fit a 50mm , you know the round clip that holds this driver in place , opening, and venting show no sign of modification in any of them
Of course it still doesn't change how they sound

Koss HV/pro capsule
(new Koss micro lightweight element design back in the 80s with better resolution compared to the older pro4AA and HV capsules)
100 Ohm
~94dB/1mw
anisotropic ferrite magnet
16 or 35 microns thick low mass diaphragm with a 4 layer self supporting voice coil.
55-57mm diameter. I need to buy a gauge,![Wink :wink: :wink:](https://cdn.head-fi.org/e/people/wink.svg)
On pair with DT880/HD6X0 capsules up to 300 Ohm.
In different variations (coating and magnet structure) used in the TD8x and pro3AAAT.
![](https://www.head-fi.org/attachments/1410093/)
Koss UR/29 capsule (SB4x too)
100 Ohm
101dB/mW
anisotropic ferrite magnet
35 microns THD stabilized diaphragm.
55-57mm diameter
Slightly better as the DKK XXL Capsules used in the AKG K2xx Series.
With different diaphragm and mangnets used in Reference, K, TD or Pro4AAAplus

Koss TD/65 capsule (the early Sony XB destroyer, not really)
90 Ohm
101dB/mW
anisotropic ferrite magnet
highly rigid diaphragm
55-57mm diameter
Edgy and hard sound signature with a Resolution on pair with the porta pro for bass lovers in big, sweaty koss pillows.
![](https://www.head-fi.org/attachments/1410097/)
Everglide S500 capsule (Fostex 90s design, like the Denon ADH930)
16 Ohm
102dB/mW
45mm diameter
A poor man Denon ADH 2000 on pair with Superlux HD681 series Resolution, maybe a bit better.
The Capsule in the picture is modified.

I uploaded my RP18 Kapton driver for a google 'deep dream'
Quite pleased with the results![Headphone Smile :) :)](https://cdn.head-fi.org/e/headfi/smily_headphones1.gif)

... wait
well then.
Those are the drivers in all the old "Audatron" branded headphones. Looks like Koss was the one who did the OEMing for Wal-Mart, not Fostex.
These drivers are quite good in the right implementation as well. I've made two headphones with these drivers using a Bang & Olufsen U70 frame and one stock damping disc in the cups. I gave them away both times, for a christmas/birthday present respectively, but for the period that I had them I couldn't help but feel like there was something "special" about the sound. I remember the soundstage being particularly fantastic.
