The EarthProof construction of Vista has achieved the IPX7 protection class for complete waterproofing and sweat resistance. All critical components are sealed against dust and dirt. Sport-Fit - interchangeable ear gel cushions in three sizes ensure a secure, ultra-comfortable fit that you barely notice during intense sports. With a full charge, you get six hours of audio plus an additional 10 hours in the charging case. A five-minute quick charge provides one hour of playback time. When used independently, the earbuds extend this to 32 hours. The Jaybird app offers unlimited EQ control over the revamped 6mm drive coils: speakers with greater precision and lower distortion. More energy for your adventures through intense sound. The Vista earbuds are among the smallest and lightest on the market - you literally forget you’re wearing them. The innovative wireless JBS1 technology delivers crystal-clear, lag-free stereo sound for video, music, and calls, along with a reliable connection that pairs effortlessly with your phone - every time.
