My new iPhone 5S was stuck in headphones mode for about 24 hours. Tried a factory reset, erase all content and settings. Plugging the headphones in and out. Nothing worked. I called Apple and they agreed to send me a replacement phone.
The next day I got an e-mail saying the new phone was shipped. About two hours later I picked up my phone off my coffee table and everything was back to normal, no longer stuck on headphone mode. Weird...
So apparently it fixed itself. But I still did return it as I got the new phone the next day.
My phone never got wet or had any moisture at all when this happened. Never was dropped or has any real explanation why it got stuck on headphones mode. I've never used the headphones...
The first problem I have with an iPhone since I've owned every one. Hopefully it will be my last.
I not responsible for any damage. Have a licensed tec check for this problem
To all of you that have had headphone problem and nothing works and have had the possibility of water damage.
This can happen up to a year after water or other liquids have come in contact with the phone.

While swiping my lock screen to take a picture, my 1 month-old iPhone 5s (7.0.4) suddenly rebooted. I noticed after a couple of hours that I was now stuck in "headphones" mode..
Before trying all the physical tips discussed in this thread, I tried to insert headphones in and out, and play youtube video, etc. no luck...
Then I've seen this post mentioning Control Center (thanks @Fraser357). I went to Control Center, started playing music again, and MAGIC, the sound came out of the iPhone's loudspeaker. Now my phone is back in regular mode.
Apple, please fix this...
Ok I had the "stuck in headphone" issue.
Solved it by:
Open control center
Select air play and found a check mark beside earphone. Did not have any plugged in.
Left the screen open
Plugged in headphones
Unplugged headphones and the check mark "headphones" changed to "iPhone"
Closed control center and it works.
Was prepared to go out and get can of compressed air, and prepared to leave in sealed zip lock baggie with rice overnight.
But first tried blowdrier on cool (which still has heat). Held it over the headphone jack about 8 inches from opening for about a minute, kept checking volume to see if headphones was indicated. After about a minute, headphone mode was released.
Thank goodness. That was 20 minutes ago and still good.
Omg!!! Two days of struggling with the phone trying to figure out what's wrong & I finally realized that this was the issue. I've tried sucking air(worked for the first try after which it reverted back to the headphones state), cleaning with a Q-tip( dunno if that worked) and then finally plugging & unplugging the earphones every time it showed 'headphones'.
Is someone having a relapse of this problem coz my phone keeps reverting back to the headphones mode. Can someone please give me a permanent solution???
For me, it was a memory issue. I deleted about 20 apps and I'm out of headphone mode. The sound is also louder than ever! Hope this helps others. I spent 2 hrs trying everything in these threads, including putting it on the freezer sucking on my headphone hole. My gf looked at me like I was crazy. Good luck!
