Beat? Lol, certainlly not an audiophile route... The beat sounds very artificial and unnaturual. Pretty much like the SRS or Sony xBass. They do certainally 'enhcance' the sound, but not quite make them sound better. Though is, it is a subjective matter.
If you want more nature sound that enhances the deetails, Viper4Android goes to top, and PureAudio is second. That IMOH the best you can go for on a software DSP solution.
