MP3 goggles are an excellent option for swimming. Most people like to listen to music when they work out. However, it's a bad idea to use your iPod or regular MP3 player in the pool.

Typical digital music players aren't waterproof. Water can damage them and make them useless.

Waterproof MP3 goggles are specifially made for those that like to burn some calories aquatically. If you fall in this category and like a soundtrack for your workout, read on.

The best waterproof MP3 players use bone conduction technology. A typical MP3 player transmits sound through air or water. If you're underwater, this can muffle the noise. With bone-conduction technology, the sound directly vibrates off the inner-ear to create a clearer experience (just make sure not to listen too loudly.)

One common worry from people told about MP3 goggles is that they will be uncomfortable. Swimming goggles are like a pair of shoes to many people. They get very comfortable with them and a slight difference can make them very uncomfortable.

If you're one of those people, don't worry! Many of these devices work in conjunction with the current pair of goggles you have.

One option like this is the Finis SwiMP3. This completely waterproof MP3 player can be purchased for about $150. It clips on to your pair of swimming goggles.

How much music can these devices hold? It varies. The Finis Swimp3 for example has 256 megabytes of storage. That means you can load about 60 songs on it. Plenty for a morning workout.

If you do use MP3 goggles while swimming, make sure you remain extra observant. Obviously, it will be harder for you to hear notices from the lifeguards and others around you. Don't kick anybody.

If you're considering buying some of a pair of these, the most important thing is to figure out what works best for you. Listening to music can be distracting for some. For others it can energize them and make them swim harder.
