- Pairing with desktop: Used very often. Never autoconnects on Linux. Requires 3-4 manual connection attempts to work. Sometimes autoconnects to Windows (same keys shared from Linux to Win).
- Pairing to work desktop: Used very often. Usually autoconnects, but always starts in HSP/HFP profile and A2DP (high quality audio) is broken until manually reconnected once. Then it works until the headphones power cycle.
- Pairing to Android: Basically never used, but generally works when needed.
