I've run into similar interference issues when building real-time audio processing systems. The AirPods Pro's use of Bluetooth 5.3 in the 2.4GHz band makes them particularly susceptible to Wi-Fi interference, especially on planes where you have dozens of devices competing in a metal tube.
One mitigation strategy we found effective was implementing dynamic frequency hopping with adaptive channel selection. By monitoring RSSI levels and packet loss rates across different channels (typically seeing -85 to -95 dBm on crowded channels vs -65 to -75 dBm on clear ones), we could proactively switch to less congested frequencies. This reduced dropout rates by about 70% in high-interference environments.
The real challenge is balancing frequency agility with audio latency - each hop adds ~2-3ms of overhead. Has anyone experimented with using the 5GHz band for wireless audio? The higher frequency would mean more attenuation but potentially much less interference.
