I have an ASUS Zenfone 8 and I love that even the latest version still has a 3.5mm out, but I just started poking around in the settings for my Samsung Galaxy tablet and realized that Samsung Galaxy devices get Dolby Atmos. (Movies have never been better!) It got me thinking, what phones do other auditorily-inclined people use? Does AptX/LDAC support matter to you? Does audio go into your purchasing decisions at all?
Use an iPhone XR. Pair it with a Qudelix 5k and my IEMs.
I have an iPhone X and simply pair it with a Sennheiser.
This is what I am doing too, just get any phone you like and use the Qudelix!
