Bluetooth Low Energy (LE) Audio has been available for several years now, based on the Bluetooth 5.2 release, with the full specifications completed in 2022. It takes time, however, for specifications to yield working devices, and in the case of LE Audio, to have true value, you need an ecosystem of compatible “other ends” – headphones, speakers, smartphone support and so on. This takes time, and so it is only now that use of LE Audio is becoming prevalent in audio solutions.
