Shure MPA-3C Music Phone Adapter for the iPhone – Now you can use your favorite audio headphones with your music phone.

If you have an iPhone, you already know that the recessed headphone jack doesn't work with your regular audio headphones. And of course, your audio headphones don't have a mic or phone controls. The answer is simply to get the Shure MPA-3C Music Phone Adapter, and you're good to go. Plug one end of the adapter into your iPhone (it also works with other music phones), then plug your regular audio headphones into the other end. Presto...you now have an iPhone compatible set of headphones, and can listen to your music and use the controls and mic on the Shure MPA-3C to make and answer calls. This is a great way to upgrade from the earbuds that came with your music phone, without having to replace your favorite set of headphones. The Deal: Get the Shure MPA-3C Music Phone Adapter from Amazon for $31.44.
