Ever wondered why your Bluetooth headset switches from a very high quality audio experience, to a tiny mono-sound experience when entering video calls? In this blog post we’ll explain exactly what and why that happens, and what’s being done on the Bluetooth side to improve our collective audio experience in the future.

You’ve probably experienced listening to music on your wireless headphones on your way into a video call, only for that music to sound thin and cheap as soon as the hair check pops up. Or listening to music on your iPhone when an incoming call disturbs your peace, only for your music to now sound weird, louder, and as if it was recorded inside a tin can.

What's happening behind the scenes is that your Bluetooth headphones are switching from a high-quality audio profile meant for music, to a lower quality, audio delay optimized profile meant for phone calls.

In this post we'll introduce you to Bluetooth audio profiles.  We'll look at the two primary profiles, Advanced Audio Distribution Profile (A2DP) and Headset and Hands-Free Profiles (HSP/HFP) and the use cases where each profile excels. We'll also look out into the future of Bluetooth audio and where the experience for audio will improve. Finally, we’ll give you some tips on how to avoid this jarring switch in your next video call.
