R2R is for the purists, and few get purer than RS2. HiBy Music distilled the necessities from their pioneer RS6 for pure file music playback in a mini-form factor. Clearly enough, to land on Headfonia's Recommended Buys list, with no shortage of the R2R experience for Headfonics.
While being the smaller sibling, RS2 plays music back with a sonic truth and a particular delicacy and refinement only possible from R2R, but different to its Darwin counterpart. Those with a tremendous personal music library of files will be particular enamoured with RS2's dual micro SD card slots for up to 4TB of storage.
