Just a minor observation.
I was just playing a rap song titled Put On by Young Jeezy and Kanye West from 2008 (or so, I think). It came up randomly on Poweramp in my newly acquired Samsung Galaxy SI (the Vibrant) that a friend just handed to me when he got a Galaxy Note recently. I, of course, rooted it and installed Voodoo Sound to hear what all the fuss was about.
On the SI, I have the bass boost gain on +11dB. I have the Headphone amp at -10dB. Other settings include Anti-Jitter, HiFi Play, and DAC Direct.
Put On is nothing special as a song but it starts with four consecutive long bass notes that get deeper in succession. Then, it moves to five bass notes with the fourth being a short higher bass hit, then it drops for the fifth and deepest. All the bass notes in the song are of the same volume (weight and mass).
On the Galaxy SI (with Voodoo) the first note is loud and it fades with each note as they get deeper. On the last bass note (the deepest) the SI gets faint and weak (losing volume and weight). It's kinda sad.
Next, I tried my own phone, the Galaxy SII (SGH-T989 T-Mobile). The SII did better than the SI. On the SII the first three notes are about the same with less of a loss on the fourth and deepest note. I was shocked. I assumed the SII did it all (as well as any).
On my RockBox'd Sansa Clip+, all the notes have the same volume and weight thru the succession. Way to go Clip+. I knew it was the fun(est) on Hip/Hop and Rap music. Now, I have direct evidence as to why. It's a little bass monster. I just thought it paired well with portable headphone amps thru the headphone out. It's more than that though. Also, I have the RockBox setting V shaped.
I use to blame the headphones for a “mid(ish)” bass bump. It's not the headphones. BTW, I used the UE Superfi 5 EB, Sennheiser IE8, and AKG K26P for this little comparison. None of this headphones are shy when it comes to bass and they are all easy to drive.
