Swimming lap after lap has often been a silent, solo grind for many swimmers. We all know music is the best motivator there is and other sports certainly swear beats help them hit their goals.  Now swimmers can tap into BPMs to hit PBs. The FINIS DUO waterproof MP3 player lets swimmers enjoy music underwater.

What is the FINIS Duo MP3 Player?

It's like a gadget straight out of a Bond Film. This is a music player that is so clever it doesn't even have headphones.  The unit has pads that attach to your goggles and these pads transmit music using bone conduction so you hear music that is crystal clear in the water.  What that means is this ingenious two-piece design beams your favourite tracks through your cheekbones straight into your inner ear!

The Duo stores and plays MP3 music files. Most downloaded songs can be converted to MP3 format using iTunes. Up to 1,000 songs can be stored on the Duo and music is loaded via an easy drag-and-drop process using the Duo charging cable and any computer.

How does the FINIS Duo MP3 player deliver music underwater?

You are probably thinking, “Electricity and water don’t go together too well. How do you ACTUALLY prevent water from entering the headphones?”  Well, thanks to something called hydrophobic coating, music in the water is possible.  The coating repels water particles by having a low-energy surface that promotes the formation of water beads that resist and glide off the unit's surface.

That said, it is important to note the difference between water-resistant and waterproof. Water-resistant devices come with a rating of IPX3 to IPX7, with an increasing amount of resistant to droplets and sprays of moisture.  On the other hand, waterproof devices are rated IPX7 to IPX9k. They allow for full immersion in water with increasing depth and time.  The Duo is IPX8.

More good news, you can be swimming to the beat in a matter of days. Our Australian-based stock is ready to ship Aussie-wide, across the ditch and around Asia. 

Here's how the FINIS Duo underwater MP3 player will change your swimming forever:

Not only has swimming become more popular on a competitive level, but it has also become the go-to exercise for those wanting a low-impact, effective and balanced workout.

But most exercise comes with music attached - there is nothing better than sweating it out with your favourite tunes for motivation.  Swimming has lacked this icing on the exercise cake... until now.

FINIS introduced the Duo, a submersible music player that is completely waterproof and had the beats to take your workout to a whole new level.

An integrated clip design secures The Duo™ to goggle straps to rest on the cheekbones for a comfortable and streamlined fit.  The simple interface offers four buttons to easily navigate between songs, podcasts, audiobooks and other supported audio files.

Tested at 3 meters (10 feet) for 30 minutes
Immersion at 3 meters (10 feet) or deeper for over 30 minutes may result in damage

The FINIS Duo does sound like a game changer -  but don't take our word for it:

"Best thing I ever bought, end of.  Seriously this is fantastic the only device which sounds louder in the water than out. Can hear plain as day. Works during Butterfly, Breast Stroke Front Crawl and Back Crawl, diving in and tumbling." - ERM

"It's addicting in the sense that once you get introduced to this style of patent pending bone conduction audio, it's hard to imagine going back." - DOLPHINDUDE

"I like to swim for exercise but on the whole find it a little tedious. Having read the reviews of various waterproof music players Finis Duo were the ones that topped the list. I love the fact that the music plays through cheek bones so you do not have anything in your ears. The sound is crystal clear." - PETA ASHWORTH


The laps will fly by with a little help from FINIS and The Duo™ MP3 player.  Check out full reviews and how the Duo turned swimming on its head here...
