I tried the new iOS app with the DSP cable, and the cable still alive. The app does not detect the cable (AKA I cannot modify the EQ values), but the iPhone does detect the cable as a headphone.
Not sure what caused your cable to die, but I cannot reproduce your issue on an iPhone 15 Pro Max.
I agree with you regarding Moondrop and their after-sales service. My Dusk has developed cracks in the 2pin connector within 2 months of use and Moondrop did not care as long as the IEMs still functions as normal…
