How do I fix this sound quality issue I have with a DAC?

Specs: iPhone
Hello. I will get straight to the point. I have bought a Audioquest Dragonfly Black 1.5 to use with my Sony WHCH710N/B for Tidal. Tidal has 4 streaming qualities, and they are normal, high, hi fi, and master. When I play a master track the audio quality sounds really good, but for some reason when I play a song, plus certain videos on Instagram, after a while the sound audio becomes EXCEPTIONAL (although really crunchy at certain parts of the audio and the color on the dac switches from orange to purple). I don’t understand why this is happening. I also don’t understand why I need a DAC for this exceptional sound quality, since before August I didn’t need one and this problem came all of a sudden. All the customer support I’ve spoken to couldn’t find the root of the problem. I hope you guys can. My main goal is to get this exceptional sound quality without the use of a DAC, like how it was originally. (I have an iPhone 11 with iOS 14.2)

I'm confused, the Audioquest Dragonfly Black 1.5 has an analog output for headphones and pre-amp level audio. the Sony WHCH710N/B are wireless. So how are you connecting these?

Aslo, how are you connecting the Audioquest Dragonfly Black 1.5 to your phone?

I use a Apple Lighting to USB Camera Adapter and the Sony headphones came with a wire that I could use to make the headphones wired. An AUX cable I think it would be called.

Does the sound quality change only when you are using streaming audio? What happens when you play music that is stored on your device?
It sounds like you may have a bandwidth issue. Streaming sites will often lower the quality if it detects that their high data stream can't keep up on a lower bandwidth connection.

One more thing, you said this happened in August. Are you sure it didn't happen around September? September is when iOS 14 came out and if you look on Apple's help forums, there are a plethora of issues with iOS14. It could be related to what you are experiencing.

When I stream and download the audio it as the same audio quality. I also disabled optimized playback. Something that I didn’t mention since I thought it would make it more confusing but I’ll say anyway is that when I make the audio quality “high” the audio gets better, but when you click on it again it goes back to the bad sound quality as it was. I have tried factory resetting my iPhone and downloading the iOS again and getting all my data back through iCloud restore but the issue still persists. And how would I be able to test if the issue is with the iOS 14?

That definitely sounds like a bandwidth issue. Does it happen both on cellular service and on WiFi?

Testing if the issue is with iOS 14 is a tough one since Apple doesn't let you downgrade to the previous operating system. If it is an issue with iOS 14, I'm afraid you're stuck with it until they release a new version with the fix.

Yes. It happens on both. I tried other streaming services (qobuz and Amazon Music HD) and the same issue happens on them too. I even used qobuz on my laptop. I don’t understand what’s happening.
