I use wired DAC mode extensively with my iPhone 13 and the camera adapter and an overpriced USB cable. Initially no sound artifacts or disconnects via iPhone or iPad.
Worked pretty well until recently when hi resolution changes (e.g on Qobuz and Foobar) caused the sound output to drop. Music is still advancing on the source but no sound from the Bathys. Have to turn off DAC mode and reengage to get the sound output back. Really bad when shuffling artist playlists via Qobuz with varying resolutions.
Focal sent me a replacement which should be here next week. Crossing my fingers.
Before it stopped working well, wired DAC mode sounded best to me. With proper EQ and Mimi application (which works in DAC mode) they are starting to sound more like a $799 headphone.
