I was thinking of WiFi and how it is possible to connect multiple devices and use the internet. Why is it not possible with Bluetooth? I mean the same song from one phone being played in multiple connected speakers.
Edit: Thanks everyone for the clarifications.

The way drivers work, you can’t duplicate sound channels; one audio device at a time for each stream.
The JBL speakers can hook up to like 100 or something like that to one device. When I was in the army, we would go on long marches for miles with about 40 pounds, and I would be in the middle of the pack and we would have like 10 of these speakers spread throughout so we could play music.
Bluetooth 5.0 can do that can’t it? Was a selling point to Samsung s8 or s9 I think
There is a crucial difference here which is hidden in technical details; Bluetooth is vertically integrated, WiFi (any of the 802.11-standards) is not. You can innovate with WiFi, you cannot with Bluetooth, with Bluetooth you essentially have to follow the standard (which was set by a consortium of for-profit actors with interest of keeping actors to their detriment out of the marketplace).
If the royalty, licensing and qualification (the term they use) would look differently, or not exist at all, for Bluetooth it is very likely that there would have been more innovation with Bluetooth.
The technically interested might want to look into the Bluetooth specification, for example [https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=421043](https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=421043).

My TCL 10l has “Super Bluetooth” which can support up to 4 devices simultaneously and it has a calibration feature.
