However, when used with S3 Pro, these unsupported music formats will be available to this player. Enjoy an unprecedented master-level sound quality!

8X MQA Support
MQA audio technology is supported by Hidizes S3 Pro Portable DAC AMP, enabling you to fully "deploy" MQA files to achieve outstanding sound quality.
To achieve 8x MQA audio deployment, music services supporting MQA must be installed on playback devices (HiBy Music, TIDAL, etc.).
TIDAL Masters & HiBy Music & Apple Music
Do you have a TIDAL HiFi membership, HiBy Music, or a dongle that can unlock the true potential of Apple Music?
S3 PRO is here for you! TIDAL Audio Resources, HiBy Music MQA and Apple Music Spatial Audio and Free Lossless Audio maximize the potential and deliver the optimal performance you crave!
※ To enjoy Apple Music, you need to purchase a separate Lightning OTG cable.
