For many years I used to use a single, wired, earbud in the non-traffic side ear, with the wire going from my phone in the right rear pocket, under the jersey, and to my right ear. But now I've upgraded to a Bluetooth bud which works great and removes the wire-getting-pulled issue, UNTIL you have to wear the wireless bud under a balaclava, then the extra height of the bud battery causes the balaclava to push the bud into your ear and causing orifice discomfort over time. So when a balaclava is used, I go back to the lower profile hard wired bud.
