I would love to be able to listen to music while swimming. I try to go a few times a few week for 20-25 min each, and it'd be great to have something to listen to.
Check out the Neptune from FINIS. It's designed similarly to jawbone and does require earbuds while you're swimming. Actually works quite well. http://www.amazon.com/gp/aw/d/B00ACP3OOM (disclosure: Used to work for finis a couple of years back)
