aptXLossless + LE Audio, the most pioneering combination, yet. Transmit CD-quality music without any loss. truely distinguishing itself from other chips and codecs that employ lossy compression during data transmission.

Qualcomm's aptXlossless technology enables the transmission and faithful reproduction of CD-quality lossless audio (16-bit/44.1kHz) without any loss of information, ensuring you hear the studio audio as intended.

*Compatible with previous versions of Qualcomm aptX™ Adaptive/Classic, including 24-bit/96kHz lossless audio support at 880Kbps (~80% of lossless).

Lossless audio brings you closer to your favorite artist, allowing you to experience music as it was originally intended, Crystal 5A is fully compatible with prominent music streaming services like Spotify, Apple Music, and Tidal have either announced or introduced support for lossless audio.


Existing Bluetooth streaming technologies require audio compression for transmission, causing a loss of detail and introducing artifacts that can diminish the listening experience.

Brands on the market advertise 'Lossless Audio', but it's important to note that their 'Lossless' doesn't imply uncompressed audio. Instead, it refers to a specific type of compressed digital audio file that uses advanced data compression algorithms to preserve most of the audio track's details during compression.

For comparison, the average size of a compressed audio file like MP3, AAC, or LADC is roughly one-fourth the size of the original recording. In contrast, the average size of a lossless compressed audio file, such as FLAC or ALAC (Apple Lossless), is slightly more than half the size of the original recording.

However, our Crystal 5A True Lossless Audio takes a different approach. We utilize aptX™ Lossless + LE Audio, an innovative and integrative technology that achieves completely lossless audio without any damaging compression."
