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?

iPhone 15 Pro, iOS 17

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!

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....

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.

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.
