the iPhone doesn't have a hi-res bluetooth codec, so we aren't able to get anything other than 16/44.1, meaning that the APPs aren't really getting 24/96. Apple has this published somewhere, let me see if I can find it for reference.I just received a pair of UTWS5 yesterday and have been playing around with it. It's paired with the FH7s and an iPhone. When I am running Amazon HD, I noticed that the playback is only 16 / 44.1, whereas the track can be up to 24 / 96. When I am running AirPod Pros, it seems to play at least 24 / 48. Curious to know of this is a limitation from iOS or if I am missing something in the settings?
I've played around with the FiiO app, but its pretty barebones in terms of the ability to customize settings.
A ? for you: how do the FD7s sound with the UTWS5? I just heard the FD7 last week and was impressed with what they offer, but (obviously) did not sound the same as the IER-Z1R. I'm ordering the 7Hz Timeless today to compare; excited for the UTWS5 to be released in USA, I'll get them the day they're available.
