Waterworld Wired


(Watertown, MA) – Tired of swimming laps with nothing but the sound of water sloshing in your ears, while your land-lubber mates work out to the latest tunes or podcasts? A Watertown company has come up with a solution: an MP3 player and high-response headphones built into a stylish swimming cap.

Tuneslapper Swim Caps feature a 2 GB flash memory mp3 player embedded in flexible, waterproof plastic which is in turn incorporated into an ordinary-looking swimming cap. The manufacturer, AudioAquatics, designed the music system to be inconspicuous, in anticipation of potential objections by pool operators reluctant to allow electrical devices into the pool.

“The Tuneslapper caps are perfectly safe and operate on such low voltages that even if the battery chamber were breached there would be no danger to the user or other swimmers. Nevertheless, once you have the cap in place and turned on, no one will know you are bopping to your favorite beats,” according to Michael Feldman, AudioAquatics product designer and CEO.

The recharegable battery is built of flexible layers of lithium and ionized carbon built into the back of the cap, and recharged through a tiny connector that folds into the cap when not in use.

The headphones themselves are also an innovative flexible design, which cover the ears and offer superior acoustics, even underwater. There is even a small flexible 3-line LCD readout to deliver information on track, playlist, volume, etc.

However, adjusting the cap once in the water can be a problem, as it must be removed from the head in order to see the LCD or reach the controls, not to mention the difficulty of flying under the lifeguard’s sonar while staring at and repeatedly pressing your swimming cap. It is best to load and lock in the locker room, and then let it play throughout your swim.

Whether you fancy a leisurely crawl to Handel’s Water Music, a strong backbeat backstroke to Beastie Boys Intergalactic, a ballatic breaststroke to a Dolly Parton torcher, or a frenetic butterfly to speed thrash standards, the Tuneslapper can provide the soundtrack to those who prefer to get their exercise in the swimming pool.

    Heh. The photo looks like Aquaman. Got to wonder if tuning out of the surrounding noise is okay though. What if a speedboat is coming your way ?

    Lower my bills.

    They already make things like this. I own two diferent ones, and were I swim they don’t care if you have waterproof mp3 players in the pool at all. Nice try though.
