Iphone 7 sounds muffled

Anyone still experiencing this issue?

When talking on my Sprint iPhone 7+!im told I'm miffled and people say they have trouble hearing me.....Jud tricked up an S8+ and not expericing this issue now, I've brought my phone back to sprint and they said my microphone had lint, etc... Didn't solve the issue!!!

When to apple and the Genius Bar, failed mic test but cleaning up speaker grill, mic test passed. Still have distortion while talking...

I just got my I phone and I have tried all of the fixes people have suggested and people still have people telling me I am muffled when I talk. I don't know what to do, I am stuck with this phone for 2 yrs. Wish I had my 6 back

I there any update on Verizon/Apple solution?

This is the 2nd iPhone 7 and both phones sound very muffled on speaker to the person calling me.

I heard that the case does not matter. Also, I found under ACCESSIBILITY "mono audio" , phone noise cancellation is off. So is there an optimum configuration?

thanks!

I recommend following these steps:

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

especially the one about contacting Apple Support if nothing else works. Or make a reservation at a Genius Bar at an Apple Store near you:

If you have been testing out the new Waterproof feature, water can get into the speaker ports. simply let the device dry out overnight and try again.

Who is your carrier? There is a known problem related to Verizon's network at the moment. Verizon and Apple are working on a solution.

Perhaps it is a carrier problem. My Iphone 6 has the same issue on Verizon, but I have both another Iphone 6 and an Iphone 5s that work fine.

I had this problem. Having researched on the web and contacting apple support I tried all of the other suggestions you have received.

The problem is the microphone on the back of the phone to reduce backgound noise. I switched this off and everyone says that I sound clear (as if I'm standing next to them).

To switch off - settings / general / accessibility - scan down to hearing section and switch off phone noise cancellation.

I actually tried multiple things (called applecare, reset phone, turned phone on and off) with no luck and had researched all day long and found nothing about it.

Right before I was about to do a return and replace for my iPhone 7+ through apple, I did exactly what you're suggesting, BUT with one SMALL tweak, and it FIXED the PROBLEM.

Turning off the Phone Noise Cancellation switch ONLY, didn't work for me, I had to to turn on the Hearing Aid Mode switch as well.

ATTENTION!!!! IF YOUR IPHONE SOUNDS MUFFLED OR HURTS YOUR EARS EVEN, DO THE FOLLOWING:

Go to Settings / General / Accessibility / Hearing Devices / - and turn on the Hearing Aid Mode switch, which then turns off the Phone Noise Cancellation switch.

This worked for me! 🙂

Spot on ! Even Apple didn't know of this problem:. Solved our muffled sound issues with my wife's brand new iphone 7 plus ... thank you ..

Just turned on the hearing side option and will test when someone is awake.....Thanks for the tip,

My first iPhone and worst sound quality ever!!!!

Thank you threalbkahl! Turning on Hearing Mode Aid has resolved my muffled sound when using a folio cover that folds back to cover the rear microphone.
