OLLO Legacy
OLLO Legacy
A tribute to the models that started it all
Our legacy models are more than just past editions—they’re part of the journey that brought OLLO Audio to where it is today. Each iteration, from the early S4X and S4R to the refined versions that followed, has been built on relentless testing, real-world feedback, and the pursuit of uncompromising audio precision.
These models have been trusted in studios worldwide, shaping countless recordings and performances. While they may no longer be in production, they remain a testament to our philosophy: durable, honest, and made for creators who demand the best.
If you're looking for a piece of OLLO history or need support for your existing pair, you're in the right place.
MEET THE X1
The X1 now takes the lead as our flagship model, replacing all previous open-back designs. With a flat frequency response perfect for production and mixing, each pair is also individually calibrated using AI to deliver unparalleled precision.
