How Bluetooth Audio Streaming Works

When you pair bluetooth smart glasses with your smartphone, the device establishes a wireless connection using the A2DP (Advanced Audio Distribution Profile) protocol. Your phone’s music player or streaming app encodes audio files using a specific codec—such as AAC, SBC, or aptX—and transmits the compressed data via Bluetooth radio waves.

The glasses’ Bluetooth receiver decodes this data stream and converts it back into analog electrical signals. These signals drive the miniature speakers, producing sound waves that travel through the air directly into your ear canals. The entire process occurs with minimal latency (typically 100-200ms for standard codecs, or as low as 60ms with aptX Low Latency).
