My daughter (3 1/2 yrs old), has been enjoying my iphone very much (lots of GREAT free podcasts!), but as I found out from this Board, her listening to the podcasts through the internal speaker is eating up my battery quickly. Are there any headphones for the iphone that go over the head (the old fashioned kind), that are good for kids? I bought a headphone adapter from Apple today so that I could research headphones safe for young kids and use the adapter, but if there are headphones already out there, I'd prefer to buy them. Thanks!
