Bluetooth LE Audio - 
Low Power, High Reliability, Future-Ready

Bluetooth® LE Audio is the next-generation standard in wireless audio communication. Built on the Bluetooth 5.2 and 5.4 specifications, it enables high-quality audio streaming, lower power consumption, multi-stream capabilities, and Auracast™ broadcast audio – unlocking a whole new era for audio-enabled devices.  

In contrast to Bluetooth Classic, Bluetooth LE Audio enables studio-quality audio with lower power consumption, making audio more accessible in more use cases than ever before such as in wearables, hearing aids, industrial headsets, smart home devices, and more.
