Bluetooth is currently limited to streaming audio to just a single device. That&rsquo;s fine for portable speakers and headphones where both sides are connected with a wire, but for wireless earbuds, such as Apple&rsquo;s AirPods, your smartphone  can actually only connect to one side. That earbud then has to forward the audio stream onto the one in your other ear, which requires some clever software tricks to ensure everything remains in sync.<\/p><\/blockquote>","protected":false},"excerpt":{"rendered":"<p>Bluetooth SIG (MacRumors, Hacker News): As the names suggest, Classic Audio operates on the Bluetooth Classic radio while LE Audio operates on the Bluetooth Low Energy radio.
