Great audio engineering, poor product design.
I have quite mixed feelings about this amp/dac. I'm not an audiophile, so take my review as you wish. First - i do notice a wonderful sound improvement using this while commuting and plugged in to my iPhone. So as far as the essential core purpose of this amp, it nails it. The music sounds richer, the bass is much fuller (there are 3 settings for bass amplification), and the instruments have more clear separation. All in all, the sound is great. The red color is bright and sharp. Battery life was decent, i thought better than the last FiiO I had.The negatives are all in the user experience and product design. First of all, it comes with one connector, but you need to buy a second from apple to plug in to that connector in order to plug it into your lightning connector to source music directly and use it as a DAC. I think they should engineer a connector and include it (charge more if you need to) so that one cord can go direct from amp to phone. It's awkward to have two. The metal box itself is sharp edged. Not necessarily to cut yourself, but when holding your phone and the amp, you do have to be careful not to scratch your glass with it. And by comparison, the FiiO amp/dac is soft cornered with a softer material case too that is less likely to scratch. This feels raw by comparison. Further complaints: the switches are not intuitive. Base controls are up for off, down for medium and middle for max. Huh? The power switch is unlabeled on and off. The battery and charge modes are a bit confusing. if you accidentally leave it in charge mode while playing from your phone, it will drain your phone battery to charge it while it is playing. And worst of all...if you have it set to On and stop playing music, it will still drain the battery. In other words, even if you remove your headphones from the jack and disconnect your phone from the amp...it will still drain. I made this mistake and it drained over night.Despite these quirks, i give it 4 stars because the audio is great. I just wish they had a better product designer. This feels like it was made by engineers who didn't think about the user experience. I'm still
