Bose Ultra Open
The open-ear design uses OpenAudio tech to deliver rich, private sound while maintaining spatial awareness, with 7.5-hour battery life and IPX4 water resistance. At just 6 grams per bud, the flexible joint grip ensures a secure, comfortable fit for all-day wear, complemented by Bose Immersive Spatial Audio. Best for fitness enthusiasts and travelers who need environmental awareness, but weak call quality (49.5/100) limits use for phone-heavy work.
