Regardless of how you feel about it, wireless audio is slowly becoming the norm for mobile phones and tablets. This has caused a lot of anxiety, but there are some benefits, as well. One is the ability to send audio signals to dual Bluetooth audio simultaneously. Granted, the need for this doesn’t come along often, but it’s nice to know you have the option.
Some Samsung phones can already do this, and according to a rumor from Japanese blog Mac Otakara(spotted via Mac Rumors), Apple might be bringing the feature to future iPhones as well. There is something to bear in mind, I have this functionality on my Galaxy device (and have had it for some time), but I have no need for it. Just throwing that out there.
Being able to connect to more than one Bluetooth device can be helpful. You might want to connect your phone to your car’s audio system to give GPS instructions while also playing music through earphones, for example. (A situation suggested by Mac Otakara.) Not usually recommended using heardphones while driving. You know, safety issue and stuff.
Or, you and a friend might want to watch a film on a long journey. Being able to connect to multiple sets of headphones would allow you both to enjoy the full audio experience. (In fairness, if you have a device with a 3.5 mm jack you can just use a headphone splitter for the same affect.) None of his suggestions aren’t capable of a workaround, but I digress.
Samsung’s dual wireless audio feature is available on a handful of devices, and requires Bluetooth 5.0 to function. As Mac Rumors points out, if Apple implements dual Bluetooth audio in the same way, it could bring the functionality to older iPhones that support Bluetooth 5.0 (including the iPhone 8, iPhone X, and iPhone XS) via a software update.
But, don’t get your hopes up too high as the sourcing of this rumor isn’t amazing. Mac Otakara cites a supply chain source, but doesn’t say which iPhone model might be getting the feature. We’ll have to wait a bit longer to see what happens next. I’m still waiting for that holographic imaging we were supposed to get with the iPhone 4.
