Review: Belkin Headphone Adapter for iPhone: ”

As I noted in my article on the iPhone’s compatibility with iPod accessories, the iPhone’s headphone jack is recessed into the iPhone’s body; third-party headphones with larger miniplugs won’t work with this recessed jack.

The solution is a headphone adapter that plugs into this recessed jack and then lets you use your headphones of choice. A number of vendors, including Belkin, Griffin Technology, and Shure have announced such adapters, and we’ll be taking a look at each. The first one we’ve had in our eager hands is Belkin’s $11 Headphone Adapter for iPhone.
