Amazon Music Unlimited and HD Audio device capability w/Bose NC700
I'm curious to know if others have noticed this behavior and if it may warrant reporting as a bug or if it is expected behavior:
So I have several pairs of headphones, some wired and some wireless. When using Amazon Music Unlimited, I like my music in Ultra HD (CD quality 16bit/44.1khz and above). The NC700 is capable of 24 bit/48khz with an optimal connection to a compatible device (an Iphone 11 pro max in my case). The Amazon app often reports an incorrect device capability that is not consistent. Sometimes it will report the device as 24-bit / 48 khz and other times, 16 bit / 44.1 khz. Sometimes the audio stream will play back at a lower rate. While there are many factors that influence this (signal strength, network conditions etc), My other wireless headphones do not exhibit this behavior. The other model (beats powerbeats pro) is capable of 24 bit / 48khz as well and always, without fail reports this to the Amazon app and all audio streams reliably play at the maximum rate possible. Now both headphones operate under pretty much identical conditions. I never stray more than a few feet away from the iphone, so wireless signal quality cannot be blamed here. I have gigabit internet service and the router in my home is a recent model (Netgear C7800) with full strength wifi and no walls between the iphone and router.
I wonder - is there some minor issue between the Amazon app and the Bose NC700? Why would the Bose suffer from this issue and not my other cheaper powerbeats wireless buds?
