A few experienced competitive swimmers among the Unique Hunters family have some experience with aquatic stereo systems designed to sit at the bottom of a pool and blast music clearly through the water. Unfortunately, we haven’t enjoyed as much luck finding personal MP3 players deliver such impressive audio without water infiltration eventually shorting out earbuds and devices alike.
That was before we encountered The Duo, an IPX8 waterproof, iTunes-compatible MP3 player designed with competitive swimmers in mind to transmit perfect audio at maximum depths of 3 meters (10 feet) for up to 30 minutes*…without earbuds.
The Duo’s integrated clip rests it directly against the cheekbones by attaching it securely to the swimmer’s goggle straps for a comfortable, streamlined fit. Once activated, its innovative Bone Conduction technology delivers up to 60 hours – roughly 1,000 songs – worth of MP3 and WMA music, audiobook, and podcast playback directly to the bones of the inner ear through precisely tuned vibration. It isn’t entirely unlike the principle behind Solid Snake’s codec in “Metal Gear Solid“.
For the record, if you often swim for such prolonged lengths of time that 4GB of internal flash memory isn’t extensive enough capacity to hold all the audio you could want, then do give our regards to Aquaman.
The four-button interface allows for quick swapping between audiobooks, music, podcasts, and other formats. The only thing smoother than navigating your library via The Duo itself will be charging the device’s lithium-ion battery for up to seven hours of use and instantly transferring files with the improved universal USB magnetic dock.
*Be advised, tests show that submersion longer than 30 minutes at recommended depths or deeper can easily result in water damage to The Duo.
