Digital music aficionados who are constantly behind the wheel are often faced with the dilemma of how to connect their MP3 players to their car stereos. The lucky ones have head units with direct line-in ports, and a few may even be driving around in vehicles old enough to sport the good-old cassette deck.
Either instance requires a simple wired attachment, but for those who aren't blessed with such accouterments, playing MP3 audio in the car is a little more challenging. Two options remain: custom install a hardwire connection or play music over often-spotty FM transmitters. Thankfully, there are a handful of transmitters on the market with solid performance, including the Eznex EzCube, a tiny device that connects to any MP3 player and will set you back about $50.
