Underwater Audio did something that no one else on this list did. Unlike the rest of the guys on here, instead of making their very own product, Underwater Audio decided that they would take one of the most popular (and honestly, one of the best) dedicated MP3 players on the market, and then they would just make it waterproof. Mission accomplished.
They basically just waterproofed an iPod Shuffle. This may not seem like a big deal, but to be honest, the iPod shuffle was one of the best-selling MP3 players of its time for a reason; it was simple, easy to use, and it had a spring-loaded clip that would allow it to stay secured to you even in the event of a pretty strenuous workout. These are all things that make the iPod shuffle a great MP3 player, and adding to that the ability to take it in the water just makes it all the better.
In a lot of ways, the Underwater Audio Waterproof iPod Shuffle leads the competition. To begin with, with about fifteen hours of battery life and no screen to operate, it easily leads the pack in battery life, beating out its nearest competitor by nearly doubling the amount of time it can stay on with a single full charge. Then, of course, there’s the fact that the iPod shuffle is a tried and true MP3 player design that also gives you full access to any music you may have purchased on iTunes (which, for most people, is a lot of music).
Honestly, the only downside you will encounter (besides the limit of ten feet submersion) is that there is a limit of 2GB of space on the iPod Shuffle. That being said, 2GB is plenty for a dedicated workout iPod, and that can be something like six hundred songs of average length.
The Underwater Audio iPod Shuffle is definitely a device that you should consider if you’re looking for a waterproof MP3 player, that’s for sure.
