USB C Headphone lead on iPhone 15 SOLVED (sort of)

More problems with the way Apple have designed the USB C port.


I bought the official Apple USB C headphone lead but it didn't work. I plugged in my Bang & Olufsen wired headphones and the music continued to come out of the iPhone 15 Pro speakers.


I found many postings about failed car connection with Apple Car Play that were solved by playing one song through Apple Music.


So this evening I connected the official Apple USB C - Headphone Lead to an old Apple Ear Phone lead from an elderly iPod. Then Connected the USB C end to the iPhone 15 Pro. The phone asked if I was trying to connect a headphone so I pressed yes. Then I opened Apple Music and played a song and it came through the earpiece!


What on earth is going on?

This is the correct solution for getting phone audio out of the USBC. You are basically telling the iPhone that your accessory is a set of wired headphones. - From Tanmaynehete


To fix this issue follow below steps

go to

>> USB audio accessories >>

1st click on forget all USB Accesories

then enable connected to headphones option.

I just don't understand why this problem is not receiving more attention.


We have many people affected by the car system of Apple CarPlay and others like you who can't connect headphones. It must be a poor implementation of the USB C.


I've now found that a high quality USB C data cable can't connect the iPhone 15 Pro to the USB C port of my HP Envy AIO desktop. The computer thinks nothing is there and the iPhone does not register the computer. Totally dead. But I can use a Belkin HDMI lead to mirror the iPhone on the HP Screen.


And if I use iTunes there is still no recognition of the iPhone 15 through the USB C. The HP connection is a Thunderbolt USB C. But a cheap Lightning Female to Male USB C connector will allow an iTunes connection through the Lightning lead we use for all other household iPhones.

It's getting worse

My 'cheap' Lightning Female to Male USB C connector is the only way I can connect to iTunes. But...


It's affecting my Microsoft Outlook application on my Windows desktop!!!


I've been struggling with emails stuck in my Outlook outbox. No amount of reboots or app closures would unstick it. Until I disconnected the iPhone. The stuck items cleared and all was restored.


As a check I rebooted the desktop. Opened Outlook and completed a 'Send & Receive' with success.


Then connected the iPhone and composed a message. It stuck again.


Unplugged the iPhone and the stuck message cleared.

I too purchased the Apple 3.5 headphone adapter cable to use with a set of headphones I use with my IPhone 15. Used the same headphones on my IPhone 13 with a 3.5 adapter to lightning connector without any problems. I have just started to experience the issue where I try to play music through the headphones and the songs won’t start. I takes a hard reset to make it work. If I stop playing music for a period of time ( not sure how long) I have to reset again to play my music. Sooo frustrating especially when traveling. What will it take to get a resolution from Apple?

I just bought the iPhone 15 Pro Max. I wanted to use my EarPods that I used with my old iPhone 12 so I bought a lighting to usb-c adapter. Seemed like the cheapest solution but alas, no sound come out the EarPods, just the phone speakers. The fact that Apple was so stubborn about having a proprietary connector for so long then to finally switch to usb-c and not making sure it worked properly is extremely frustrating. I had to buy all new charging cables for my car, home, and office. I really don’t understand the rationale for the change. I stick with Apple because for the most part they get it right or fix issues right away. Come on Apple!

I’m hoping somebody can help me. I recently bought the adapter for my phone so that I could play it through my cars cassette deck. When I plugged in the adapter, my iPhone asked if it was for headphones. Since it was the adapter, I put no when I actually should have put yes. It gave me a message that I could change this in Settings but I can’t figure out how to change it. Would anybody know where I would have to go in settings to tell it that it is headphones that I’m trying to plug-in.
