You’ll be now able to control multiple, independent, synchronized audio streams from a source device – like a smartphone – to many headphones, speakers, and audio sinks. The new standard will also allow you to broadcast audio, resulting in audio sharing between headphones.
Previously, BLE (Bluetooth Low Energy) was only used for non-audio functions, like enabling remote control of consumer devices. It’s a separate radio from the Bluetooth Basic Rate and Enhanced Data Rate (BR/EDR) radios used by standard Bluetooth audio devices, which Bluetooth SIG now calls Bluetooth Classic. Streaming sound over BLE radio is made possible by the Low Complexity Communication Codec (LC3), a low-power audio codec.
Bluetooth LE will let public spaces, such as malls or gyms, provide audio streams simultaneously to their customers. This can also prove useful in museums as they’ll be able to stream tour guides in various languages directly to visitors’ phones.
BLE will also lead to the development of better hearing aids with Bluetooth support.
We might see some devices with the new standard by the end of the year. So be patient because something very exciting is on the way.
