I am selling these headphones brand new and sealed which were bundled with my new Nothing phone. I'm sure that you will be aware of the specs, I have included a Nothing / KEF description below. Nothing Headphone (1) delivers an immersive audio experience with its custom 40mm dynamic driver, engineered in partnership with KEF for natural, precise sound. It features real-time ANC that adapts to your environment, enhanced by a 4-mic ENC system to ensure crisp, clear calls even in challenging conditions. With support for Hi-Res Audio, LDAC and USB-C lossless playback, it offers unmatched audio quality.
