you uploaded 7 image files, each one size is 3MB... I think that limited bandwidth users is out of bandwidth now =D ...

also, you restore old headphones with "sony mdr62", walkman drivers,,,
It's more DIY headphones less them the original one.
it's new "sony mdr62" but with new cans.

I not like to take some picture now,
but I order 3pcs of this headphones, that once gave me on the airplane:

Sennheiser HD 16 . It uses 28mm 300ohm driver
also Walkman style that I like =D
but from high quality materials.


this is my old mod that I done on one pair

You are totally right. It is DIY. But as it was both linked to mdr62 and old europsonic vintage looking heaphones I did not know where to put this mod. But thank you for liking anyway.

Are you going to make any more youtube videos on your channel?

Also, on one of your social media, you say you have made some new headphones with your Kaldas company . will you be sharing info on head-fi or have a thread like Dan with Mr. Speakers did or Zach with ZMF?

Those Et1000 do look very cool, wish i could hear one. :D

I'll be back soon. More on Kaldas Research will follow.
Thanks for the support, man. It's been a while.

Stax Srm-1 amp
headphones: Stax Sr-30, Stax Lambda pro, Stax Sigma normal


Stax Sigma, makes some scratching noise when it amps to 3/4 of the power, tried to clean as I could but without sucsess an live it as it.
After cleaning the material on the headband damaged a bit after washing machine (next time I will wash by hand).
From past experiments, not recommended to wash the leather pads cause the glue inside them make it stinky , I only clean them with alcohol a bit.


I decide to stop ordering more headphones at this point,
If I will perches something in the future it will be some thing from the high class.

In addition I received today fixed good pair of Beyerdynamic T1, That I think that it the best!

I waiting to this pair, just for fun/ collect or just try to active and hear some nostalgic class headphones
headphones: Nathaniel Baldwin, Trimm Dependable
I really interested how this old class heard

*It have to get some big repair.
If only one side will work, I will be very happy.

After reading several pages on the very long Orthodynamic Roundup post. I decided to purchase a couple vintage orthos. Here's my additions from the past month.

Yamaha YH-3, YH-1 and Fostex T10.
