sennheiser momentum - clear vocals , nice fit in the ear( i use the xs earbuds and can jump and they won't fall out), very nice audio however the bass can fall a bit short.
sure s215- good bass , nice fit but around ear design (love or hate it) , the vocals aren't as nice as the momentum but they have got very nice sound too.
jaybird bluebird x2 , bluetooth earbuds that as the name said are bluetooth, i don't own the but people like them very much.
- its up to you but i use the momentum everyday -
about the beats my younger sister has them they say seriously lack in quality however u can get a nice price at amazon.
