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

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

sound & haptic

>>. Head phone safety

>> USB audio accessories >>

1st click on forget all USB Accesories

then enable connected to headphones option.

GOT IT!!

Sounds & Haptics

Bottom of the screen - HEADPHONE SAFETY

then USB AUDIO ACCESSORIES

Then TURN ON CONNECTED TO HEADPHONES

This got my headphones with an ol regular adapter to play media as well as audio through voice calls and video calls.

Thank (not) the Apple Gawds.

I had the same problem with a 3rd party adapter, audio would not be directed to headphones. Returned 3rd party adapter and bought official Apple adapter thinking this would solve my problem. When I used the Apple adapter same issue, no awareness on my 15 Pro that there were headphones connected and only audio on the phone (using Apple music). Tried leaving everything attached via usb c to headphone jack and restarted the 15 Pro. Upon restarting I got the message asking if there were headphones attached. I said yes and now I get audio on the headphones. I guess the 15 Pro needed a restart to "see" the headphones. This might be a solution for some.

I finally found the solution on my iPhone 15 pro. Try this out:

-Settings

-Accessibility

-Audio & Visual

-Headphone accommodations (top option)

-Turn on and adjust to your liking

…And boom plugged in my $5 generic usb-c to 3.5 headphone jack from Amazon. The message “do you want to use headphones” came up.

Been working ever since.. Hope it works for anybody else trying the same.

You are so absolutely correct. Thank you. And you can use a 3 band mic supported jack as long as you plug it in 3/4 of the way wait for the message to recognize them as headphones and then you can plug it in fully. I just can’t believe I spent 2 grand on a new phone and have to do stupid crap like this to get it to work.

I solved this issue with a rather interesting approach. I have a V-Moda Crossfade M-100 Master that I wanted to connect to my iPhone 15 Pro Max using a standard Apple USB-C to 3.5 mm audio adapter. My phone screen was locked when I plugged the USB-C adapter + headphones into the phone and a notification popped up saying "Trying to connect an accessory" or something. I lost this prompt when I got an incoming call and the iPhone routed the call directly through the phone audio bypassing the headphones + mic setup.

I restarted my phone, connected the same thing and expected to see the prompt but did not. I had to trick the phone into thinking I was doing this afresh, so I pulled the 3.5 mm audio out and slid it in halfway into the adapter till I could hear the all too familiar audio noise in the headphones, and the notification popped up again. This time I selected "Yes" and audio + microphone came through. The setup works flawlessly now.

I hope this works for everyone who has an issue as well. Thanks!

P.S: My headset comes with a microphone cable, and a plain audio cable with 3 bands.

Whelp, I figured it out (for myself at least). For me it was the fact that my 3.5mm male jack that plugs into the dongle has 3 bands (mic supported) and once I switched to a regular 2 band (sound only) 3.5mm wire, all was good.

It seems the 3.5mm to usb-c dongle doesn’t play very well with mic supported wired headphones.

This is spot-on. I play music through my iphone into a mixer during gigs to play music for the house while my band takes a break. No problem with a lightning dongle to 3.5mm cable into my mixer for years. then bought an iphone 15 and it uses a USB C, so I bought the Apple dongle to connect and now the mixer won't recognize the 3.5 mm cable. Turns out that I have to loosely connect the 3.5 to my PA mixer, but tightly connect it to the phone dongle. It works, but if the cable gets bumped while playing music, I am sure it will break up or disconnect the sound. I am using a 2-ring 3.5 mm cable. Sheesh....

you need to re-order new ones, you may have got the wrong kind that are similar but a different company makes them and it familiar with it because i’ve bought the same kind. you got t make sure it says “apple usb-c earphones” always make sure apple is in the name, otherwise their going to be a janky kind

I had the same thing happen and didn't notice in the description it read "not for audio." So I purchased a different one that stated it was a converter for audio. It arrived today. have my Apple Earpods connected to it and tried it on my iPhone 15—works perfectly.

USB C Male to Lightning Female Adapter. Supports audio, charge, and data

So I too switched to a headset with just the two bands after reading this post in January and have been listening to music successfully ever since. Thanks!!

I’m having the same issue trying to figure out why my Meze 99’s won’t work with the usb-c to headphone adapter, but my old Apple wired earbuds work flawlessly every time.

I got the Meze 99’s to work only once by taking your suggestion and playing a song in the native Apple Music app. I unplugged the 99’s and haven’t been able to get sound out of them again, even by restarting the phone.

So weird and frustrating.
