I've heard the Galaxy 5.0 and it sounds a lot like my T-Mobile version Galaxy SII (SGH-T989).
I love my SII's sound with Poweramp 2. It's as if Poweramp uses the surround-sound that's horribly implemented by Android's own music player. The Poweramp sound is like when you use the front-rear fade control on your car system to hear the back speakers slightly over the front (depth moves back in your head).
My Shure SE535's normally strong forward mids are moved back in balance with the rest of the music (with an isolated lead singer). The vocals are so precise (and concise) and the tone sounds like I'd expect the actually singers to sound if they were in a small venue nearby and I was a bit away from the stage. I often rewind passages in songs because background singing harmony sounds so beautiful.
Of course, this is on the go listening for me. I'm not judging critical detail while driving the truck, although I do hear things I've never heard in a portable (with emphasis in instrumentation that I never noticed before). I notice stereo effects that make me go back and compare with my Apple DAPs and I say; oh yeah, it was there. It was just fuzzy and clustered into a small sound-stage, whereas, with the SII/SE535s the sound-stage is wide and deep. My AKG Q701s have nothing but height on the SII/SE535 combo sound-stage.
It's important to me that the synthesizer clap, snare drum lick, and lead singer aren't disproportionately louder (taller, blurry, and more upfront) than the rest of the instrumentation like with my Apple DAPs and my sister's iPhone 4s (using the 535s).
I can feel the contact made to percussion instruments, yet, not so much with the most upfront of those instruments (which may be part of the “musical” aspect of the Shure earphones). It's such a great characteristic in an otherwise noisy environment. Also, the bass (tube-like) resonance sound good even when the motor of the truck is particularly loud while changing gears. There's no competing going on.
I often listen at less than one/half of half volume (that right, ¼ volume). I recently realized that the reason I don't feel the need to turn the volume up is because I can hear everything at this level (layers/transparency/depth).
With my RockBox'd Clip+/FiiO E11/Q701 combo (at home in a quiet place) I have to turn the volume up to compensate for background singing that sometimes competes with other instrumentation. That combo sounds pretty good, but the vocals don't move me like the SII/SE535s do.
Sorry, I've got to stop posting like this (like it's an irrelevant off-subject word count contest).
