i have an JBL FLIP 4 Bluetooth speaker that provides great quality sound, especially for its size and the JBL app even allows for two of these speakers to become connected via Bluetooth to my iOS device and provide a much more rich stereo sound. In order for me to use the speaker I have to enter setting on my iOS device, go to Bluetooth and click on the speaker I wish to connect to. It’s been years since I used AirPlay and the only time I did was with an old AirPort express I had that was connected to Logitech speakers via an audio jack. I’m wondering how much more beneficial AirPlay is today and why I would want to use that exclusively instead of the dozens and dozens of great quality Bluetooth speakers that are usually turned on at all times in my home. The one difference I foresee is that if I don’t play audio for a while, say an hour, I have to go back into settings to reconnect the speaker, so long as the speaker is powered on.
