Lightning to 3.5mm Headphone Jack Adapter disconnects phone calles after crackling sound

I have a new iPhone SE (2nd gen) with a pair of Parsons branded earbuds that has a standard 3.5 mm audio plug. I use an Apple brand 3.5 mm-to-Lightning connector to plug my earbuds into my iPhone SE. When on phone calls, it works perfectly, but occasional it doesn't per below:

I hear a distinctive crackling sound, then it disconnects my phone call.
I hear a distinctive crackling sound, then it disconnects my phone call, then opens my iPhone music app and starts to play a song.

Does anyone know what causes this, and what's the fix?

Many thanks!

iPhone SE, iOS 14

Hi rsirotek,

We understand you're having audio issues with pair of headphones. We're happy to offer some guidance.

You'll want to isolate if the problem is coming from the headphones or the adapter. There's two ways you can test this out. If you have another set of headphones, connect them to that adapter and see if you have the same audio quality issues. You can also connect the headphones to another device that has a 3.5mm audio jack to see if you have the audio quality issues there.

If another set of headphones connected to the adapter has the same audio quality issue, then you'll know the problem is the adapter. If the headphones have the same audio quality issue when connected to another device, then you'll know the problem is the headphones.

Here's some other general steps you can try for headphone issues: If your headphones don't work with your iPhone, iPad, or iPod touch

We hope this helps. Take care!

Hi rsirotek,

Thanks for the follow up! It sounds like you did some great isolation steps. So if the headphones work everywhere else, and you've been able to test another adapter, that leaves the lightning port as the only thing in this connection chain that remained the same.

This would indicate the problem is coming from the lighting port. We'd recommend checking the port for any dirt/debris. If anything is packed in there, it's best to use a soft brush to clean it, don't use anything sharp that could cause damage.

Also, to your point about the adapters, while the likelihood of two adapters having the same issue is incredibly slim, it still doesn't hurt to completely rule that out. If you have access to any other Apple devices with a lightning port, you can test out the adapters just to make sure they do not exhibit the same behavior as they do on your phone.

If the adapters are working fine on other devices, or you've checked the lighting port and it is free of dirt/debris, you'll want to have the device serviced. You can find available service options for iPhone here: iPhone Repair and Service

Cheers!

Thank you Leanne.

The headphones on various devices behave properly, i.e. no emanating crackling sound or disconnects. That would point to the 3.5 mm-to-lightning adapter as the culprit, but ....

I have 2 adapters and both exhibit the same crackling sound followed by a telephone call disconnect. It could be both Apple-made adapters are defective, but what are the odds of that. Given that small probability both are defective, I posted here to see if others were experiencing phone call disconnects pointing to perhaps more probability of some sort of general connection issue with lightning technology or otherwise.

Any thought anyone?
