iPhone 7 Audio Jack Adapter Issues

Since getting my iPhone 7 I've noticed issues when connecting the phone to my car via the 3.5mm-to-lightning adapter. Every so often the phone will refuse to acknowledge that there is an audio source plugged in and the sound will randomly switch from the car speakers to the iPhone's speakers.


For the time being I am having to disconnect the cable (aux cord + 3.5mm-to-lightning adapter) from the phone and reconnect it, and that only solves the problem 8 out of 10 times. In certain instances even that will fail to fix the problem and I will be left with a phone that cannot connect to my car. I have noticed it start to happen more frequently since installing iOS 10.0.2.


I am wondering if this is more an issue of the phone or the adapter not working properly. Please help.


Note: I have tried connecting the aux cord to another source via the headphone jack and can confirm that there is no problem with the cable.

iPhone 7, iOS 10.0.2

I've had the "7" since it first came out. I connect to my car stereo the same way that you do and I've never had a problem.


First, you should update to the latest iOS. I don't know if it was a typo or if you really have 10.02 but the latest is 10.2.


Second, the next time that you use it in your car, be especially careful to ensure that the adapter is fully plugged in to the phone and that the wire is not routed in such a way that that connection can be disturbed.

I have the same issue. My music mostly stops playing when I get a phone call. If I do not get a phone call my music stops by itself after a while, and I can't get it back. The problem is with the iPhone though not the cable. I've tried the cable and adapter on the iPhone 6 and it works perfectly fine, then I plug in my iPhone 7 and it doesn't work. I hope they fix this glitch on the next update because it is very annoying, I use my music a lot while driving.

I have a similar issue only it doesn't ever resolve. I drove home listening to music via the lighting adapter to my 3.5mm cable just fine. I parked and when I went out a couple hours later I was no longer able to listen to music. I tested the dongle using my old 3.5 mm headphone jack and it worked fine. But it would not play either through my car stereo audio jack or through my home stereo audio jack .

I just used my 'adapter' in my iPhone 7 plus today and noticed that... it didn't work at all. Every split second I get static/music/static/music as the songs continue to play. I knew the adapter wouldn't work once I found out that they were giving us something free with our expensive iPhones with no headphone jack. My earbuds are OEM Samsung and I refuse to go out and buy new earbuds from another company just to see if it is an issue with that model of earbuds. My Samsung earbuds work with everything else so there is no reason the adapter shouldn't work with all 3.5mm headphones. Oh well, guess I'll use the Apple earpods and continuously keep putting them back in my ears as they fall out constantly until I can find a pair of good bluetooth earbuds.

I have been having issues since i had gotten my iPhone 7!!!!!! I can't even you my samsung headphones on my iPhone 7 via adapter. It makes a wierd crackle noise and doesn't corectly play the audio. Sure, i get that something like that will happen, but i had stuck with samsungs headphones when i had stuck with android phone since i started to have my first phone long ago, but the bounderies of me using a enemy company's headphone on a apple device shouldn't be a thing!!! >:(

I have this problem. I'm using Sony MDR-EX650 earphones, I don't have a problem on any other device so I know it is a problem with the adapter and not the earphones themselves.


Most of the time, when listening using these earphones through the lightening adapater I get constant electrical pulses which distort the music / cause static / stop and start the music or podcast. I can also get very high pitched feedback which is painful and obviously means I have to unplug my earphones. I would say the maximum amount of time I've been able to listen with no distruption is c. 20 minutes.


This has to be a problem with the adapter / electrical system in the iPhone 7 when the adapter is used. I know I could use the earphones provided but they don't fit my ears, the sound isn't as good and, if an adapter is provided, it should work.


Does anyone else have this issue? I've seen a lot of people having a problem with Bose headphones but less so with 'normal' in ear earphones like mine. Any ideas?! I actually bought a new adapter as I thought I had lost my old one (it was in a hole in my pocket in the end, ha) but I got the same problem, so I know it isn't a physical problem with the adapter unless I have been very unlucky.
