Bluetooth audio has evolved significantly over 25 years, from Basic Rate (BR) radio in 1999 to the modern LE Audio architecture. Key milestones include the introduction of A2DP for stereo streaming, Bluetooth Low Energy (BLE), and the transformative Bluetooth 5.2 LE Audio standard. LE Audio introduces isochronous channels (CIS for unicast, BIS/Auracast for broadcast), the LC3 codec delivering better quality at lower bitrates than SBC, and coordinated sets for true wireless stereo without relay architectures. These advances benefit hearing aids (longer battery life, better intelligibility), gaming headsets (low-latency stereo with bidirectional audio), and public broadcast scenarios (Auracast enabling one-to-many audio delivery up to 100m outdoors). Audio testing with anthropomorphic fixtures and updated test systems like Audio Precision's Bluetooth 5 module is essential to validate real-world performance.
