I have bought a FiiO X3 me some time ago. The sound was very good, unfortunately the software has not always done as I would have liked. Now I have purchased my FiiO X5 and am currently totally satisfied: - He looks good, feel and appearance go fully in order - The software does what it should, so far I've had no major problems with it. - The operation is simple and mostly intuitive - The battery life is very neat - You can use 2 SD cards with up to 128GB at the same time !!! +++ !!! - The volume can be more than sufficient untwist - Probably there will again be software updates that bring any improvements or eliminate small mistakes. - And the best: the sound is simply fantastic, pleasant and not too bass or treble-heavy. Only recordings in poor quality sound so somehow even worse. This I now eliminate successively.
One drawback to the conclusion: The number of tracks is limitate to 5800 if you want to let the title go to Tags. Playing for Files is also possible with more titles.
