The H2O Interval fits easily on my goggles strap and I can listen to music or podcasts of my choice while swimming laps. It makes doing those laps a lot more enjoyable. And if you don't have an ipod shuffle third gen it's easy to pick up a used one cheap.

I LOVE having music to listen to when I swim laps.  It has made all the difference.  I went from swimming 1/2 mile a day to 1 mile a day all because I wasn't bored.  HOWEVER, the first headphone lasted 2 months before one of the ear pieces went bad.  I'm on my second one and one of the earpieces doesn't put out the same volume as the other, so it sounds like all the music is coming from one side.  I should probably return it and get another brand.

Product sounds great when working but after a few weeks one ear bud went muffled then rarely worked.  It would cut back on on occasion but mostly stopped working.  SwimOutlet was great about replacing this with a new device but after a few weeks the new device developed the same problems.  I also had trouble with ear buds coming out about a mile into my swim.  If they even come partially out the sound is shot and will not improve until its had hours to dry out.  I think its just a manufacturer issue.    

On the bright side, SwimOutlet has offered outstanding service in resolving these issues.  Thanks!

this is a really cool item, but they need to do some work on the headphones as I have ahad trouble with another unit and one of the headphones going out

love it! You have to configure it exactly to your liking, otherwise the ear pieces will keep falling out. I put them on and put my swim cap over them just for extra protection. Otherwise, the sound is great! I would definitely recommend this product to anyone who swims!

It rarely falls out of my ears.  It sounds surprisingly clean but does become inbalanced on occasion, which is easily fixed per directions.  It's compact and easy to use.  You just have to remember to open it and turn off the player.
