Every headphone colors the sound in its own way. Atrium ships a correction profile per model — measured frequency-response compensation that flattens what your headphone does to the sound before your personal tuning is applied on top.
Atrium still works — every feature runs on any headphone; you just won't get the model-specific correction layer. The hearing tests, your Signature, and the spatial engine adapt to whatever you're wearing.
The library is growing toward the open measurement ecosystem — thousands of models. Want yours prioritized? Tell us which one.
