Summary: I loved my swim today with my new Interval! I even got the XS size ear fittings to seal well in my ears, which was my main concern. Wearing a swimming cap helped. The Interval stayed put on my goggles strap and it played my playlist for an hour in the pool, with fairly good sound quality for a little player. It might have been my imagination, but I think having my Interval encouraging me along, I might have swum a bit faster!
Pros: Durable, High Quality, Lightweight, Good Fit
Summary: I have had two ipod nano's die on me due to exposure to sweat while running (I live in a tropical climate with high temps and humidity). Although this product costs more than the ipod shuffle it houses I thought it would be worthwhile to save my shuffle.
