Fitbit is jumping headfirst into the smartwatch market with the newly announced Ionic. But alongside its new wearable, the fitness tracker company is also entering another new field today: headphones, with the new Fitbit Flyer.

The Flyers are a fairly ordinary pair of fitness-focused Bluetooth headphones. They’re designed to be sweat-proof and water resistant, so they’ll survive a serious workout or a sudden rain shower. Fitbit claims they’ll last around six hours of use off a single charge, with a 15-minute quick charge to get another hour of battery life. And despite being a device released in late 2017, they charge over Micro USB instead of the newer USB-C standard.
