You could use some Amplifier for headphones.
Best pair of headphones that I have so far.I listen to wide range of music, from Classical, underground Rap and Hip Hop, R'n'B, Soul, over all variations Jazz, Blues, Hard Rock, Alternative, Avant-garde, to all kinds of Metal, Rock and Pop, World Music, Electronic, Native, Folk, Oldies etc..so far, they are good for me.Not an audiomaniac, so I don't care that much about technical stuff, just trying to get the most out of what I have.
Bass is not that flat as they say in reviews all over the internet, but a bit more bass wouldn't hurt.Maybe not for bassheads, but I find them very good for Hip-Hop, cos too much of bass kills the rest of beat, even though most of listeners like massive bass(which is cool, but I like to hear that extra stuff that rappers and DJ's use for samples in that kind of music)
Right now im listening the new Ghostface Killah album Sour Soul, which is a combo of hip-hop and jazz instrumental music, and it sounds great on these headphones.
I use them on sandisk sport, phone, tablet, computer and Marshall amp.As they all say for a $100, hard to find something better for average user.
They are very comfortable for my head, but I needed a little time to get used to them.I came from AKG K77, so I'm used to that kind of design.I like the earpads, much more softer than those on AKG's.
