The open-ear design pairs Bose Immersive Spatial Audio with OpenAudio tech for private, rich sound while maintaining awareness, backed by a 7.5-hour bud battery and 27-hour total case life. Its 6g weight, IPX4 rating, and quick-charge (10 minutes for 2 hours) make it a rugged choice for constant movement. Best for runners and urban commuters who need situational awareness without sacrificing music, though its weak 48.2/100 call score makes it a poor fit for heavy phone use.
