For better or worse, wireless audio is slowly becoming the norm for mobile phones and tablets. This has caused a lot of irritation, but there are also benefits. One is the ability to send audio signals to two separate Bluetooth devices simultaneously. Some Samsung phones can already do this, and according to a Japanese blog rumor Mac Otakara (discovered via Mac Rumors ), Apple can also bring the function of future iPhones as well. 19659003] Being able to connect more than one Bluetooth device can be useful in a number of scenarios. You may want to connect your phone to your car's audio system to provide GPS instructions while also playing music through earphones, for example. (A situation suggested by Mac Otakara .) Or you and a friend may want to watch a movie on a long journey. Being able to connect multiple sets of headphones allows you both to enjoy the entire audio experience. (In fairness, if you have a device with 3.5mm connector, you can only use a headphone separator for the same effect.)
Samsung's two wireless audio feature is available on a handful of devices and requires Bluetooth 5.0 to work. As Mac Rumors points out that if Apple implements dual sound in the same way, it can bring the functionality of older iPhones that support Bluetooth 5.0 (including the iPhone 8, iPhone X and iPhone XS) through a software update.
But don't get your hopes too high, since the sourcing of these rumors is not amazing. Mac Otakara cites a supply chain source, but does not say which iPhone model can get the feature. We have to wait a little longer to see what happens next.
