I'm not exactly sure what the title should be. I'm using some Bluetooth headphones and they connect perfectly with my MacBook Pro. Thing is, whenever I receive a Skype call (I believe anything where a microphone is involved), it switches to "tinny" sound quality. Not sure why this is - it happened on my old Windows laptop as well. On Windows, you can go to the sound preferences and choose whether it should output the sound through 'Headphones' or 'Headphones - Handsfree'. When it is on handsfree, the audio turns tinny as well. How can I make sure it always is connected to non-handsfree in macOS? Lately, a video application I use (that doesn't use the microphone) periodically switches to the tinny sound profile, making the video sound terrible. I can reproduce the sound by playing something in the background, go to Sound preferences -> Input and select the bluetooth device. If I instead select the Internal Microphone, the MacBook will still switch to the other tinny profile. Any idea? Maybe I can completely delete the bluetooth headphone from the "Input"?
