Error Theory

Strive for perfection.

× .audio

We’re proud to officially announce our partnership with Xan Audio.

From the very first conversation, it was clear we share the same obsession — precision, clarity and uncompromising sound. Perfection in soundwaves is what brought us together, and this is only the beginning.

Expect more power.
More depth.
More intensity.

Let’s push the limits 🔥

Go and drop them a DM with the craziest custom in-ear design you can ever come up with... and they will make it even better 😎



Do you have yours?

"Dear Error Theory supporters,

with heavy heart I want to let you know that in 2026 I need to take a break from the band.

The reason for this are a few random events in my life that have made it necessary for me to focus on my personal life right now.

This isn't goodbye.
Maybe I won't participate in the production of upcoming music as much as before but you will see me and hear me from time to time in the Error Theory ether.

Thank you for all your support, messages, and energy — it really means a lot to me."
