Loading up the player with some bangin' tunes and Samsungs quality audio electronics are obvious once it's going. The sounds in pure mode (no DNSe or street mode enhancement) come in crisp and clear to the ears.
The player also has the ability to drive some serious headphones, not just a pair of ear buds. Plugging in my Sony reference cans, you do have to up the volume a little more, but the sound quality remains awesome right up to the full end.
Using the DNSe to enhance the sound helps if you want to help bring out certain aspects of your music, like the bass if you are a hardcore d'n'b nut or maybe to accentuate the high end if you get down with your classical side!
Street mode adds that nice bit of depth to the music by pushing up the EQ on the frequencies that are most likely drowned out by background noise in a street environment; this to give you a richer sound-scape.
A nifty feature is also the inclusion of a screensaver in the form of a real-time EQ bar graph set, with the added ability to pulse the lights of the touch zones rhythmically in time with the music.
