You iPhone’s headphone jack is just fine for listening to your MP3s with the crappy Apple-supplied earbuds, but what if you want something a little, shall we say, less terrible? You could of course spring for a high-end headphone amp with its own DAC (Digital Analog Converter), and pay hundreds of dollars for the privilege. Or you could dig $11 out from under the couch cushions and buy CableJive’s LineOut Pro.
