QCBridge brings convenient Bose QuietComfort 45 controls to your Windows desktop. Connect your paired QC45 headphones and quickly check battery status, switch between Quiet and Aware listening modes, adjust the built-in three-band equalizer, and control Windows audio without reaching for another device. QCBridge is designed to stay out of the way when you don't need it. Keep it running in the Windows system tray for quick access to commonly used headphone controls. Automatic connection and reconnection help restore your QC45 session when your headphones are powered back on, Bluetooth becomes available again, or Windows resumes from sleep. View useful headphone information including model, firmware, product details, and the active Windows Bluetooth audio profile. QCBridge also includes configurable Windows startup behavior, low-battery notifications, light and dark theme support, keyboard navigation, and accessibility-focused interface improvements. QCBridge currently supports Bose QuietComfort 45 (QC45) headphones only. A Bluetooth-enabled Windows PC and QC45 headphones paired through Windows are required.
