Check your Bluetooth headset's microphone and speaker with a continuous live audio loop before a call. HandsFreeCheck sends the microphone signal back to your headset while displaying separate microphone and speaker waveforms with dBFS levels. Features • Live Bluetooth hands-free microphone monitoring • Separate microphone and speaker signal displays • Input and output device names • Adjustable monitoring level • Pause and resume • Automatic connection handling Audio is processed on your device. Nothing is recorded or uploaded. No account, ads, or subscription. Connect your headset in Bluetooth settings, open the app, allow microphone access, and speak. The app requires a Bluetooth Hands-Free Profile (HFP) device with both microphone and speaker support, including compatible AirPods. Without a compatible device, the app waits for a connection. Bluetooth monitoring introduces some delay. The speaker trace shows the app's digital output, not an acoustic measurement. This is a live communication-route check, not an independent left/right speaker test. A later phone call may select a different audio route. Compatible with iPhone and iPad running iOS 15 or later.
