The BlueAnt Pump is a rugged set of Bluetooth headphones meant to survive sweat and rain, but to see just how waterproof it really is, I took it for a head-first dive down a natural stone waterfall slide in South Carolina.
To shoot the below video of this real-life torture test, I connected the Pump to my Moto X and made a call to a voice-recording service while shooting a video of me sliding down the falls with the phone. The resulting footage features the actual headset audio from the Pump's microphones as it (and I) get a little soaked.
As you can hear, not only does the Pump have decent range for a wireless sports headset, it also barely misses a beat after getting submerged. The water runs out of my ear, and the sound quickly normalizes to the same quality level as we heard when it was dry.
I was also able to hear audio through the headset before it had even fully dried out. All in all, the Pump does seem to be as waterproof as advertised.
