A:Answer As pointed out, these are lighter than the previous generation earbuds. They are also smaller so people with smaller ear canals, that experienced issues before, shouldn't have any issues. I highly recommend using the included ComplyFoam tips instead of the silicon/rubber ones. Not only are they lighter but, for me, they make a better seal and are a lot more comfortable. I usually have issues with earbuds that have rubber/silicon tips. They never, ever stay in my ears and Bose was the only company that made earbuds I actually liked and would fit in my ears. Jaybird has really knocked it out of the park for me with these. They fit in my ears just as well, if not better, than my Bose earbuds and better than any other earbuds on the market. I've tried wireless earbuds from Sony, LG, JBL/Under Armor, Phillips, Beats, Skullcandy, and Sol Republic. The Jaybird Freedom earbuds, with their ComplyFoam and ear wings, are the only ones that have stayed in my ears whether I'm bending over picking up stuff, working my lab, sitting at my desk, or walking a few miles in the hot sun.
