Why does my Nano keep turning itself off?

Yes when pushing in the headphones, they have to click. No shiny part should be showing.

Make sure your headphones are pushed all the way in.

"Same problem - Different solution:

Check your jack for JUNK!

Shine a flashlight in that hole. I found some POCKET LINT that was jammed in the socket preventing the headphones from fully seating. I used an ordinary toothpick to sweep it out. Works great now!"

if you look closely at your head phone jack you will notice the he phones aren't all the way inn to you half to push them all the way you will hear a pop and the sound causality will be better

"Well I had same issue and the FM radio could not see the antenna (audio plug).

Here I was blaming a firmware update :o(.

But I saw this post and double checked plug , appeared to be in all the way. I could not apply anymore pressure.

Then I tried a bent paper clip in the slot and out popped a bit of pocket lint!

All is working now.

Check the lint trap!!!

"Have had three new nanos all ended up doing same thing volume going down by its self. Apple has problem with these and knows its in moisture getting in some where( thinks its volume bottoms ) I cut off end to a charging cable and left in when running with my nano. Did not help same thing happened on third nano. Try taking dry toothbrush and cleaning charging port and head phone port, helps sometimes!

Apple needs to own up to problem just like they finally did on iPhone antenna / bumper problem. Class action suit would help on nano problem!"
