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.

Bluetooth apps engineer here. Many have touched on why it isn’t widely seen, mainly because of synchronization issues. There are many devices that now have their own proprietary method for handling this. The Bluetooth SIG understands the current limitation and future specification will handle this more gracefully. Particularly, in Bluetooth Low Energy’s implementation (Bluetooth classics younger brother, think sensors and wearables). If you’re interested in more info, here they describe LE audio and broadcast mode – https://www.bluetooth.com/learn-about-bluetooth/recent-enhancements/le-audio/. This will take some years for mass adoption but will handle exactly this scenario.
I,ve done it before but you gotta mess around with it to get them exactly synced like once they are both playing you gotta pause it then start again so they both start together.
Bluetooth isn’t a wire, there is a lot of lag in the compression, sending (and resending dropouts), decomposition, device processing and finaly pumping it out.
If the two devices aren’t in exactly the same time it will sound shit. So until recently no one has spent the time to enable such a feature.
Manufacturers are starting to add meshing between their own brands, Bluetooth 5 is adding some delay info to potentially allow this between brands.
I actually bought a Bluetooth speaker for my truck because the speakers in it don’t work. And the speaker I bought said you can link up to 100 of them together. So… I guess technically the phone is only connecting to 1 and then each speaker is connecting to the next one.
you can there is already a solution provided by multiple brands that do this.
one company is ultimateears
the other is Sonos
Does bluetooth 5.0 solve all of this?
Pairing…to pair a pair of devices…is this a hint? /s
Thinking about that: if you could pair multiple Bluetooth earpieces to a single phone, it would allow to easily speak together when you’re out in a bike ride.
Same reason you can’t listen to multiple people speaking at once in a crowded room; you only have one receiver in your ears.
Speakers can only tune to one source at a time unless they’re designed to accept multiple, though few will because…well, when is that ever needed.
My old Samsung S10 did dual audio via bluetooth. My girl and I used to use it when we went jogging.
