This player has a very engaging sound, I think the vocal sound fantastic on this player. Pretty dynamic with capable up pushing out significant bass quantity. It makes some of the recordings that are generally unexciting sounding fun to listen to.
Although I like the sound, there are few of down sides. With my Andromeda which is quite sensitive, I hear static sound with the music. UI is ancient. With all the Android based DAPs out now a days, why such an old UI? Navigating though songs can be easier. I heard Lotoo is a microphone recorder brand so I understand why the UI graphics look like ones for the recorders. Big downside is that it doesn't work as a USB DAC.
The parametric EQ is quite nice, and it is the best one I've experienced. EQ performs very well compared to others I've tried on phone and DAPs. It can lift bass with EQ pretty significantly. It is the only player that brings out the best of the iSine 20 planar magnetic iem. EQs the iSine really well. It boggles my mind how well it drives the iSine.
Ether Flow on the other hand didn't sound so good out of it. Ether Flow can push out glare with the wrong source I think.
If you look at the player, it does have an appearance of snake oil product(with the bling and all), but I got to say it does sound good, and the music out of it is engaging particularly.
