Bluetooth

Getting Bluetooth headphones or headsets to work with the Zoom Android app can be a frustrating experience. This quick post documents the issue I ran into along with its solution.

This is a follow-up to my earlier article Bluetooth Audio Quality & aptX on Windows 10, based on a comment by reader eluxe. Windows makes it unnecessarily hard to identify the audio codec used by the Bluetooth A2DP profile, but there is a way. This post shows how to check if your connection makes use of aptX, LDAC, or some other more advanced codec, or if it falls back to SBC.

Bluetooth is a flexible standard. It defines various profiles that operate on top of the Bluetooth networking protocol stack and implement specific services, such as hands-free communications. Bluetooth devices each support a small subset of profiles, typically only one or two, according to their designated function.
