There are three ways: Either I receive headphones to work on them, or I source the headphones locally. Or you buy pre-made units like you would any other product.
First method: I receive headphones to work on them. I do not supply them.
The big reason for this is that people send me all sorts of ‘unicorn’ vintage Sennheisers that they want me to work on.
Are there sonic differences between vintage and modern? Yes. So this is how it usually works.
The secondary reason is that people like how a certain stock pair they have sounds, and want them worked by me. Because, each pair sounds different, no matter how good Senn matching is.
Second method: Sometimes I am able to source pairs locally, and most people have opted for this option.
With this option, this saves you shipping cost and time. And it’s very convenient.
However, I will need to buy new earpads at your cost, and also you won’t have control over the exact pair I’ll be using.
A long time ago, I used to supply pairs myself because I wanted to be able to offer a single consistent sonic profiles. But this has now proven impossible because of some changes to how Senn operates (especially how parts are much harder to source now).
Third method: You can buy pre-made pairs that sometimes I post, or on Nitsch. Sometimes I don’t update what I’ve got or what I’m working on, so shoot me an email.
Important: Know what you are asking for, know what you are getting!
Read the headphone page, other sections of the site, impressions, etc, to fully know what you’re asking for. If you have questions, email me.
If you want a super-HD650 type sound, obviously you should be going for a JAR650, not JAR600, right?
As a friend put it to me: “JAR- We turn horses into unicorns, but not into different animals!”
