When it comes to waterproof mp3 players, two popular options stand out from the rest: the Sony NW-WS413 and the FINIS Duo. Both devices are designed for swimmers, surfers, and water sports enthusiasts who want to enjoy their favorite tunes while in the water. In this comparison, we'll dive into the features, performance, and design of each product to help you decide which one is right for you.

Design and Build

The Sony NW-WS413 has a sleek and compact design, weighing only 32 grams. It's made of durable plastic and has a waterproof rating of IPX8, meaning it can withstand being submerged in water up to 2 meters deep for up to 30 minutes. The device has a simple and intuitive interface, with a single button that controls playback, volume, and track selection.

The FINIS Duo, on the other hand, has a more rugged design, with a waterproof rating of IPX8 as well. It's slightly larger than the Sony NW-WS413, but still compact enough to fit comfortably behind your ear. The FINIS Duo has a unique design feature - it uses bone conduction technology to transmit sound through your cheekbones, rather than traditional earbuds. This allows for a more secure and comfortable fit, especially during intense water activities.

Sound Quality

Both devices offer excellent sound quality, but in different ways. The Sony NW-WS413 has traditional earbuds that provide clear and balanced audio, with good bass response and decent treble clarity. However, the sound can be affected by the water pressure and noise of the surroundings.

The FINIS Duo's bone conduction technology provides a unique listening experience. Since the sound is transmitted through your cheekbones, it's less affected by water noise and pressure. The audio quality is clear and crisp, with good mid-range response, but may lack some bass depth compared to traditional earbuds.

Storage and Battery Life

The Sony NW-WS413 has 4GB of internal storage, which can hold up to 1,000 songs. It also supports microSD cards, allowing you to expand your music library. The battery life is impressive, with up to 12 hours of playback on a single charge.

The FINIS Duo has 4GB of internal storage as well, but it doesn't support microSD cards. However, it has a longer battery life, with up to 15 hours of playback on a single charge. Both devices can be easily charged via USB.

Additional Features

Both waterproof mp3 players have some additional features worth mentioning. The Sony NW-WS413 has a built-in FM radio and supports Bluetooth connectivity, allowing you to stream music from your phone or other devices. It also has a handy "drag and drop" feature, making it easy to transfer music files from your computer.

The FINIS Duo has a more limited feature set, but it's designed specifically for swimmers and water athletes. It has a built-in interval timer and a repeat mode, allowing you to focus on your training without distractions.

Conclusion

In conclusion, both the Sony NW-WS413 and the FINIS Duo are excellent waterproof mp3 players designed for water sports enthusiasts. The Sony NW-WS413 offers traditional earbuds with good sound quality, expandable storage, and additional features like FM radio and Bluetooth connectivity. The FINIS Duo, on the other hand, uses innovative bone conduction technology to provide a unique listening experience, with a more secure and comfortable fit.

Ultimately, the choice between these two devices depends on your personal preferences and needs. If you prioritize sound quality and want a more traditional listening experience, the Sony NW-WS413 may be the better choice. However, if you're looking for a device specifically designed for swimmers and water athletes, with a secure and comfortable fit, the FINIS Duo is an excellent option. Both devices are great examples of waterproof mp3 players that can enhance your aquatic adventures.
