A friend of mine semi-permanently attached his dongle to his headphones by heatshrinking over the joined headphone jack/socket (after having lost several already). Seems to be a neat/workable solution. (I've never had my dongle come accidentally detached from my headphones. Maybe the tolerances in my headphone jack and my dongle socket all serendipitously turned out "just right"...)
