    MEIZU Hifi Pro USB-C Phone Dongle DAC Review

    As it is said a few messages above, it could be related to low impedance IEMS. Andromeda Campfire IEM are 12,8 Ohm impedance, so it seems it is related to very low impedance IEMS. It would be good if you can test with any other medium or high impedance headsets or IEMS to pinpoint if said...

    MEIZU Hifi Pro USB-C Phone Dongle DAC Review

    Usually low impedance IEMS should be more prone to take "noise" as they are much more sensitive to minimal voltage variations, that could come from interference for example in the mobile phone from a mouse, wifi, even internal from the mobile.

    Review and Measurements of Monoprice THX Desktop DAC & Amp

    Hi Silver2545, I have this issue with IEMS and it was solved "grounding" the case to "ground" cable on the plug. Perhaps this would help. See post #55,

    Review: Apple vs Google USB-C Headphone Adapters

    The only issue I see with my Galaxy tab S6 is, if I have a headset with volume controls when you try to up or down the volume goes all way up or all way down, not step by step. The issue comes down to Apple manage volume control in a different way, but otherwise I have no issue with it. If...
