Thanko goes waterproof with their new EMP-708LITE Vonia earphones that feature bone conduction technology, just like how the Aliph Jawbone Bluetooth headsets work, save for the fact that this pair is waterproof. Just make sure you won’t dive more than 5 meters and the EMP-708LITE Vonia earphones ought to be able to hold up pretty nicely. In addition, we’d recommend you get a decent waterproof case for your portable media player that you want to bring with you when racking up those laps at the community pool. This Japan-only device will retail for $45 thereabouts.
