While out for a run today, the pairing between my headphones and Spark Cardio dropped. To repair, I had to end my run, pair the headphones again, and start a new run on the Spark? Shouldn't the Spark be able to pair automatically, especially during an activity? If it does not, then I would like to add that to the suggestion box. It seems unnecessary to stop and restart my tracking just to get my headphones paired.
