The KDMAS is more intended as on ear Audio. The DMAS is still in testing and Development. Atm there are 10 pimax owners testing the DMAS audio. Hopefully we have an update on progress.
The KDMAS is compatible with all pimax hmds. While the SMAS and upcoming DMAS require a stronger Audio amp in the headset; compatible with: 8k+, 8kX, 5kSuper and I believe revised Artisan that uses USB Power.
KDMAS headphones are still going well. Be interesting to see how the DMAS models perform against these when they eventually release. I have these headphones and 3d printed adapters for comfort strap if someone makes a reasonable offer.
The connecting interface looks like Pimax DMAS, maybe it would be possible to use them on our HMDs?
A proper click-click on-off ear design, it would be better if Pimax just sell those, as good user experience is more important than questional “best sound quality” of DMAS.
