I know that they are not truly wireless, but I am really enjoying my Jaybird Freedoms. They are indeed very tiny and fits very well in my ears. For running they are almost perfect. Only issue is the battery package, which may get you a little sore after some time. I have recently bought the E8 and while I do love them (very few drop outs), I would not use them for running - slightly too bulky compared with the fredoms.
