Preamble: I had an Iphone 7 for about a year and had my music downloaded onto it to listen in my car while driving about over Bluetooth. Worked flawlessly. I then traded it in for a Note 9 after missing the customization of Android. Synced the phone up to the car aaaaaand it crackles at higher frequency notes, especially during voice sections in songs. Thought it was my Sync2 head unit being quirky, and then I tried it with my roommate's UE speaker... and it's still cracking.
I've already scoured forum after forum from times long gone, and I can't find any answers that have worked. I've tried everything short of factory resetting the phone. Re-pairing the device, turning it off and back on, trying multiple music apps, removing objects in the vicinity that could cause interference (which I found out my Drive Safe and Save beacon amplifies the crackles substantially when it turns on. It also runs off of the phone's Bluetooth), and trying to mess with the developer options. Side note: The developer options for bluetooth reset themselves to default within a minute or two? Really?
Listening to music through the phone's speakers or through headphones is fine. It's just on Bluetooth where things go awry.
