I am a big fan of Shure earbuds. Currently using the SE215, but previously used a set of SE310. The SE215's can be found online for ~ $100. I bought mine at Guitar Center for $108 out the door. They fit well in my ear and underneath a fullface helmet. The SE215's come with several different size foam sleeves, but I have found that the silicone triple flange sleeves fit my ear best. Unfortunately, the triple flange sleeves don't come with the SE215's but can be ordered as an accessory. I had to trim the stalk to get the proper length for my ear. Putting them in your ear is awkward at first because the wire comes out the top of the earbud and wraps around the back side of the ear, but once you get familiar with it it is easy.
