I had a set of E2c earbuds and they were great. I managed to get some decent base out of them though if you after head thumping base you will need your eq. After experience this seems to depend a lot on how good a seal you get in your ear.
The first thing i would DEFINATLY suggest is getting the "black soft flex sleeves". It'll save you buying tho phone tips every few days (though they do give a better seal) and will/should feel a lot more comfortable then the transparent ones that are a bit thick.
If i remember correctly they did howl in the wind but wont all earbuds do that?
I had to change mine though as a break seemed to occur within the wire right next to the plug. I changed them for a set of Ultimate Ears Super.fi 5 Pros which are great (and have changeable wires which is what put me off getting another shure set).
After a few months it'll all be second nature if this is your first set of in ear earbuds.
