iPhone Xs Bluetooth audio quality

I connect my phone to my car to listen to music. I primarily use Apple Music. iPhone XS has a problem with audio quality. The quality keeps dropping for a few seconds, then switches to high quality for a few seconds, and this keeps going like that. The issue is with treble. It's as if the 10kHz gain is reduced and then brought back up. Kinda like years ago when you tried to stream music and started with low quality and became high quality after enough buffering...


This doesn't happen with the iPhone 7s we have, running iOS12. Car is 2014 BMW 3 series


I have gone through the full on/off cycle with the car, phone, and forgetting/pairing bluetooth again without success.


Any suggestions?

iPhone XS, iOS 12

I'm experiencing the same exact super annoying issue after iOS update. The only work around I found is to turn off WiFi when using Bluetooth in my car to have good audio quality (normally use Spotify). Hope apple fix this asap, is really (REALLY) annoying.

This is unrelated to this issue i am afraid..

as of now, i've still not seen a single person in any of the threads mentioning they had any problems with interference before the software update, myself included..

Taking into accord that most of the complaints are with/in cars, i'd say the chance of 2.4GHz interference is pretty shallow..

Thats probably not related. For good audio quality over Bluetooth both the receiver and the transmitting device need to support either AAC or AptX codec. iPhones have AAC support and Android devices usually AptX. So if you’re streaming Bluetooth from an iPhone to an Android device the codecs are not compatible and transmission will fall back to the SBC codec which sounds terrible.

Hi,


I am experiencing the same issue with the high and low pitches missing, however the issue occurs for me when my IPhone X (iOS 12.2) is connected by wire to the stereo in my car and playing Spotify or ITunes.

I have a 2018 Audi A3 with a Audi Sound System. I got Audi to run an analysis and they didn’t find any issues in the car and told me that they think the issue is that the receiver is protecting the sound system from the signal coming from the phone and an issue with Apple CarPlay.

So it seems like the same issue, but with the difference that I seem to be the only one in this forum who experience it when using Bluetooth and also wired.


Hoping for a solution to the issue!

That's complete nonsense.


If it's happening both wired and via Bluetooth it's an issue with the way the DAC in the Audi is handling the signal.


As an example, music sounds wonderful over Bluetooth on a Denon D-M41 mini home stereo.


Were this a Bluetooth issue per se, it would not.

Wired or wireless, using the lightning to 3.5mm dongle or bluetooth, gives poor audio quality from my Xs MAX. I'm not sure when it started to occur, I assume from day 1 that i received my new phone. The music feels "flat". Now the gotcha: Using the 6s from my wife, and the music is plentyfull again. Got this issue when connected to my car radio (bluetooth), also when using monitors at home (wired). Again, issue is gone when using the 6s in both places... if you ask me, its hardware related...
