iPhone 7 lightning to audio jack issues

I have an iPhone 7 and I use the new Audeze Sines lightening headphones. They sound great with one MAJOR exception. They don't play loud. Nothing wrong with my new headphones. It has something to do with Apple's iPhone 7 lightening port and its inability to play music at a louder level. I've downloaded a number of volume booster apps to see if that might help. It does increase the volume but distorts the sound.

I have the same problem, or even worst.

I am music teacher, and very often I have to play some music in the classroom for my students, so it must sound very loud, and I used to connect my older iPhone 4 to the stereo system using the "3,5 jack to 2RCA stereo audio cable" (a cable connecting my phone to the auxiliary input of the stereo, normally on the back of it). With my iPhone 4 it worked perfectly. I could use either the headphones or this cable and listen to the music with the stereo system.

But now I have the iPhone 7... with no jack connection. So I bought the adaptor (Lightning to headphone jack). But in my case it only works with the headphones!!! If I connect this cable I mentioned, the stereo system doesn't get any audio signal at all.

Is it normal? Am I doing something wrong or must change something on the configuration of my iPhone? Or is just that the iphone is not capable of sending such a normal signal through the adaptor and it only works with headphones (which would be very disappointing)?

Could anyone help, please? I called to apple technical support and they didn't have any solution.

Thanks in advance!!!

I also connect my phone with lightning Jack with my earphones and my car but then I have been using them for months until yesterday. It keeps distorted the whole time and I have to hold lightning and turnt it until I get no distortion. Even if I tried with different earphones, it doesn't make any difference.

I've not had the issues you're describing at all.

As far as a "fix" by Apple, not sure that there's anything "broke" to fix. In any case, as we're users here on this forum, we would have no idea what Apple would do. Speculation is prohibited by the Terms of Use of this forum.

Hey I have this exact same issue, and it is making me crazy. I have to use the adapter to use the stereo in the fitness classroom that I teach spin classes in. I can't even TOUCH the adapter to the jack without a pop, and distortion. Same as you, any volume, any equalization anything - so bad I cannot use the speakers. Just finding that you have the issue too makes me realize I'm not losing my mind, it IS that adapter causing the problem.

OK Apple - now its time to fix the (real!) issue. I hope maybe by now something has surfaced to help?

I am having this same issue with an iPhone 7 plus. The lightening headphones not working I don't know why

I have a similar issue.

With the lightening to jack adapter, I'm having issues listening to music after less than two months of use: sound is popping and cracking very often. It's seems to be linked to the adapter as I have no issue with the headphones on my MacBook Pro 2016 and listening to music via bluetooth on the iPhone creates no such issue.

Also, and this is the issue you're describing if I understood correctly, I recently tried to connect via the adapter my iPhone to a couple of old amplified Bose speakers. The level of noise was so intense and distortions were such that listening to the music was not possible. Again, tried with another Apple product (iPad Air 2) with headphone jack on the same speakers = no problem.

@Apple: If I want to continue to use my headphones what solution do you recommend?

Using an iPhone 7 Plus with iOS 10.2 (14C92)

Same thing to me. Anything that you listening using the lightning jack the sound gain to high and the voice to high with less bass and sometimes the sound get to distortion. In my case I got a iphone 7 plus, but I did a comparison test between iphone 7 regular and iphone 7 plus and the regular 7 was fine. Its happening on plus. Solution is use the Bluetooth to listenning the music. Using Bluetooth you will get back again the sound stabilized.
