100+ Head-Fier
As a 507 owner, yes the play time isn't as long as some proprietary music players, but it runs android so uses more battery than most others. Obviously this is for the market that likes to use tidal/quobuz etc. And with high gain and no volume cap, it really is an amazing sounding player. If you fit this market it's a great device. It powers the lcdi4 comfortably.
