iPhone X poor call sound with bluetooth in car

Hi there, Grahamell!
Thanks for reaching out to the Apple Support Communities! It sounds like you are having an issue with the sound quality on your car stereo when you have your iPhone X connected and I am happy to assist! That is a great steps checking other devices and since they are not having the same issue, I suggest taking a look at this article to Get help connecting your iPhone, iPad, or iPod touch with your car stereo and follow the steps in the Bluetooth section to try disconnecting and reconnecting the iPhone. This article will also give you next steps if you continue to have issues.
Cheers!

I have the same issue, the sound is clear on my end, but the other end says I my voice quality is poor. i have seen suggestions that this is related to the bluetooth 5 chipset and not unique to Apple.

I have same issues never had an issue until the iPhone X pretty new holden cars commodore and Cruze a lot clear in the car but not the other end even if calling a mobile or landline phone needs an update

I have opened a ticket with Apple and their solution, like always, recover the iPhone. I have done it with Apple Watch and of course, it didn't solve the issue. I'm recovering my iPhone X to see if it solves the issue. If not, I will call support again and waste more time.

That’s it. Problem solved! I can’t believe that Apple can’t figure it out on the new phones. I’ve never had a problem until I got the new iPhone 8 and spent 2 weeks repeating everything I said when talking on my phone in the car.

Apple should fix this!

Hi. I have reset the iPhone X and the Apple Watch and same result. Now, they told me to go to a store to review it physically. I'm still waiting for a slot in their agenda.

This is annoying and very bad support quality.

It wasn’t resolved bar telling me to reboot the iPhone X which helped that night but I found out later that having the iwatch on impacted the call so turning off the iwatch made the call a lot clearer pretty poor hey

I have a 2011 Range Rover Sport and I am experiencing the exact same thing, extremely static call quality. I have reset network settings and rebooted my phone. When talking with Apple they were not helpful at all, basically reading off a script and stating they have no clue. I am in my vehicle and on the phone everyday and I am extremely frustrated

I tested this as I have the same issue.

I have a Audi A6 and when I had my Iphone 7 with Apple Watch I never had any problems.

When I changed to Iphone X I started getting really bad sound quality in the car.

I could hear the other person great, but they could barely hear me.

As soon as I put the watch in flight mode the sound gets good.

I have this problem too with iPhone X and Seat BT handsfree built in to the car. I can confirm that after turning on airplane mode on the watch, the sound quality on the phone calls is back to normal.

I have the same issue , my Jabra Bluetooth earpiece is giving out really poor sound quality , I can hear the caller fine but they can’t hear me very well , I put my watch in airplane mode and the sound clears , I have found tho if I connect To my AirPods the sound is fine both ways , so im wondering if there is a Bluetooth 5 earpiece that will work with the watch connected and if so which one ?

I hope anyone has had success with this, but I doubt it... Please if anyone has any info please pass it along. I have spent hours on the phone with Apple and they know about it but do NOT have any answers. Thanks

I upgraded to an iPhone X three months ago and bought my first Apple Watch at the same time. Soon after I began experiencing the exact same problems described here. I have a 2013 Lexus and brought it to the dealership for troubleshooting. They were kind enough to pair my iPhone X with multiple brand new cars and of course the problem followed me, confirming it was an issue with the phone, not the car. The only way I could temporarily resolve it was to do a hard reset on the phone. I opened 3 tickets with Apple overall the course of several weeks culminating in a replacement of my iphone X (which has not solved the problem). I have given up opening additional tickets as the most frustrating thing has been they (Apple) has not yet “acknowledged” this as a common problem and each time they react as if this issue is unique to me and so they don’t know what is happening or how to help me. I was relieved (and felt validated) to finally find this thread with recent posts from numerous people experiencing this issue. I hope if enough people raise awareness of this huge inconvenience (and dangerous problem to not be able to use Bluetooth while driving) that Apple will provide a proper and permanent fix.

Thank you so much this worked perfectly. Whilst my Apple Watch was on airplane mode the phone conversations via my new Discovery 5 were perfect as soon as I took Apple Watch off airplane mode the person on the other end of the phone complained of the crackling and noise and poor sound quality.

I am having the same issue with my Iphone X using the car bluetooth. I tried the tips in the link and it still has poor audio quality. I can hear them fine, but they say my audio sounds like I am underwater, or crackling noise. Other phones work fine in the same car on bluetooth. Looks like an issue with the Iphone X.
