Fiio X1 Portable High Resolution Lossless Music Player. Introducing the new FiiO X1 MP3 player. This is the most affordable model in FiiO's range of DAP's and boasts the same sound quality and build quality as their other products. It's essentially a mini version of the FiiO X3 product which doesn't have built in memory as it uses Micro SD cards to store your music and drops support for DSD Playback and USB DAC functionality. The reduction in features results in a much smaller and cheaper device without impacting on the quality of the main features.
