S3

The Qualcomm S3 Sound Platforms are for mid-tier audio solutions, designed to power compact, feature-rich wireless earbuds, headsets, and speakers.

The Qualcomm S3 Sound platform delivers strong audio performance with an ultra-low-power Bluetooth® 5.3 dual-mode radio and Snapdragon Sound™ technology, enabling immersive experiences for work, gaming, music, and social media. Building on this foundation, the Qualcomm S3 Gen 2 Sound Platform introduces Bluetooth® 5.4 support and expands LE Audio capabilities—including Unicast, Broadcast, and Auracast™—while adding features like Hybrid Adaptive ANC, Lossless audio, stereo recording, and voice-back channels for gaming.
