Hi Titans,
thanks for your details reply. just some clarifications:
in 2) you mention "connect your M1s to iPhone/iPad/MacBook etc" - do you mean connect by wire? if yes which cable are you using?
in 4) you mention "if I haven't enabled the AptX HD from the iPhone app and even I have LDAC selected from the M1s, Momentum 4 connect with AptX HD". to my knowledge the iPhone can only use AAC or SBC codecs and not AptX HD. With this in mind are you stating that you have selected the M1s bluetooth codec from an app within the iPhone?
I was trying the creative W5 earlier today but the disturbance was quite high with crackling, losses of the song etc. This would be a huge deal for me if I can play tidal / Apple Music etc from my iPhone to my LDAC or APTx HD to my bt headsets.
I just want to be 100% want to be sure as I have invested a few hundred in dongles and the hiBy r2 which was promised as a fix.
At the end of the day I want to use this device as a DAC and a Bluetooth transmitter. I don't care for any other built in features and I will never put in a memory card to play music as I stream everything and that which I have encoded is all in ALAC which requires an Apple Music player.
