I think you might find that it’s the balanced output on the Q1ii. I have a Q1ii and I get the same thing with the FH5. Try moving it away from a phone or anything connected to wifi/Bluetooth as the Q1ii is fairly well known to not have good shielding from outside interference. Hope that helps.
Thank you so much for your help. I thought that was probably the case, as the 1more's were connected to the regular 3.5mm output Unfortunately as you can see, I'm using the FiiO CL06 cable as this is the only one I've found that doesn't charge the DAC !! And it's brilliant and compact, for listening out and about,, but doesn't allow for the DAC to be moved away from my Note 9! Is there anything I can place between the 2 (I have the silicone pad that came with the Q1ii but can't imagine that's gonna make a difference??) or disable on my phone that will help?
