Though certainly convenient, listening to music through earphones plugged into a smartphone is not always a satisfying experience. Some music lovers, like myself, prefer to carry around a dedicated high quality audio player, while others who like to groove on the move might give the source audio a welcome boost by using a mini middleman like Cambridge Audio's DacMagic XS
. Either way, higher quality comes at the expense of increased pocket bulk. The folks at Hong Kong-based Zorloo claim that they've managed to shrink down a digital-to-analog converter, headphone amp and control board to dimensions small enough for integration into the inline playback/volume controller of the company's upcoming Z:ero earphones.
