I built a free native macOS controller for B&W headphones
I own a Px7 S3 and got tired of reaching for the phone app whenever I wanted to change something, so I built HeadBridge.
It lives in the macOS menu bar and deliberately looks like the native Sound panel. On my Px7 S3 it controls ANC / pass-through / off, five-band EQ, True Immersion, wear detection and sensitivity, standby time, the quick-action button, and voice prompts. It also shows battery history and can restore my preferred settings after a phone changes them.
This is not meant to pretend that unofficial headphone tools never existed. I wanted one free, open-source app that can support B&W, Sony, and future community providers in the same UI.
Px7 S3 is the only B&W model I can personally test, so other recent PX/PI models are marked experimental rather than supported. Reports and hardware-tested PRs are welcome.
It is an early beta, MIT licensed, with no account or analytics. The GitHub build is self-signed rather than Apple-notarized, and the README explains the installer and Gatekeeper behavior before the download command.

I would love feedback from other B&W owners. Please include the exact model and which controls worked or did not work.
