Anker, a battery maker turned accessory house, recently releases the $39 Spirit X earbuds under their Soundcore brand. Aimed at runners and other heavy sweaters, the earbuds are completely waterproof under the IPX7 rating, a classification that means it can stand up to 1 meter of submersion.
What this means is that you get a surprisingly cheap and rugged set of work-out earbuds that you’re not afraid to get a little dirty.
I tested a pair and found them quite nice for running. The rubber ear hooks kept them in place and the sound quality was not horrible, especially compared to my previous pair of Philips corded headphones. The sound quality, while a bit muffled, is what you’d expect from a standard pair of sports headphones and the rubber earbuds stayed in place quite nicely. The company claims that the headphones have a 12 hour battery life which is about right – I used them for a few days and saw little change in the battery level.
A small flap on the bottom of the control bar hides a micro USB port for charging and there are three buttons – volume up, track advance, and volume down. There are no voice prompts but there is a built-in microphone for calls.
These are not swimming headphones. The IPX7 rating means they’ll stand up to sweat and rain but not a few dozen laps in the pool. A aqua-phobic nano-coating keeps the drops out of the inside of the headphones and should let you keep trucking long after other headphones have rusted out.
