Personalised hearing calibration becomes a defining feature across the Nothing ecosystem
27th October 2025: Audiodo are pleased to share the news of their expanding partnership with Nothing, announcing that Audiodo Personal Sound will be coming to Nothing Headphone (1) via an over-the-air update rolling out globally from 27th October 2025.
The update gives all Nothing Headphone (1) users access to Audiodo’s advanced hearing calibration technology, available directly through the Nothing X app. In just minutes, listeners can complete a short in-app hearing test and create a fully personalised sound profile precisely tuned to the way they hear.
A Growing Collaboration
Audiodo Personal Sound has already become an integral feature within the Nothing and CMF by Nothing families, appearing across multiple devices including:
· Nothing Ear (3) – the first Nothing product to feature Audiodo built-in.
· CMF Buds 2 Plus – introducing personalised hearing to CMF’s true wireless range.
· CMF Headphone Pro – extending the experience to CMF’s flagship over-ear model.
With Headphone (1), that same personalised listening experience now arrives on Nothing’s first full-size headphone, cementing Audiodo Personal Sound as a defining feature across the ecosystem.
A Growing Force in Audio
Beyond Nothing, Audiodo’s software has become an irreplaceable part of a growing number of brands worldwide. From Fresh ‘n Rebel to Noble Audio, Audiodo’s sound personalisation continues to transform the way consumers experience audio across a wide range of products and price points. Several additional brand integrations are already confirmed, with more big names set to be announced soon — highlighting the increasing demand for truly personal sound.
Audiodo Personal Sound
At the core of this collaboration is Audiodo Personal Sound – advanced calibration software that analyses how each ear hears different frequencies and compensates for any variation. Using a short hearing test within the Nothing X app, the software builds a detailed map of the listener’s hearing and applies a bespoke correction curve to optimise playback in real time.
This ensures that every listener hears music as it was intended – with restored balance, enhanced clarity and accurate detail across the frequency spectrum – delivering a sound experience that’s natural, immersive and completely personal.
