Is Jasse actually real?
This is a surprisingly common question. We understand the suspicion. A man who claims he can hear a 0.3 decibel frequency response difference at 14 kHz sounds made up. Like someone wrote a character for an anime series.
But Jasse "Jazmanaut" Kesti is a real person. He eats, drinks, sleeps, and tunes frequency responses. Mostly tunes frequency responses.
Evidence
- He has a national ID number. We've checked.
- He consumes coffee in quantities that exceed AI simulation capabilities.
- He has been spotted in Kajaani. More than once. This is strong evidence, because nobody makes up being in Kajaani voluntarily.
- He has tuned the sound of every Valco headphone by hand. This explains why they sound great and why Jasse has a permanent neck and shoulder problem.
A technical fact for the skeptics
Jasse's work isn't just mysticism. The frequency response of every headphone model is measured and adjusted to match the Harman curve, which is based on Sean Olive's research into what kind of sound most people find pleasant. Jasse then makes his own adjustments on top of that, because slavishly following the curve produces a clinical sound. You need a human ear. Jasse's ear.
Conspiracy theories
Still, some customers believe that:
- Jasse is an AI. He's not. An AI doesn't drink three litres of coffee a day or complain about its back.
- Jasse is multiple people. This is only possible in the sense that after coffee he works like three people.
- Jasse is a byproduct of the Death Star project. We have no comment on this.
Can you meet Jasse?
In theory, yes. In practice, he's in the studio or the service department in Kajaani with headphones on and can't hear the doorbell. Because the headphones are Valco, the isolation is excellent.
If you still doubt Jasse's existence, order a pair of headphones and listen. That sound isn't made by an algorithm. It's made by a man with a coffee cup in one hand and a frequency analyser in the other.
We need Jasse. Without him, we'd just have plastic cans that sound like music coming from the bottom of a bucket. And then nobody would buy them, and the Death Star would never be completed.
