One of my biggest gripes with the iPhone is the recessed headphone jack. This jack configuration eliminates the majority of consumer headphones because they use a standard 3.5mm headphone plug. Until recently, the only options for getting an iPhone headphone adapter was to buy one of the bulky models from Belkin or buying an iPod Shuffle headphone extension cable on ebay. Luckily, the folks at USBFever have come to the rescue with their iPod / iPhone Stereo Earphone Adapter. This little device can get your Shure/Bose/Etymotic headphones working on your iPhone.
