*Battery life varies by volume, content and environment.

Why You’ll Love S911

• Run safer with open-ear awareness — Hear traffic, teammates, and cues without blocking your ear canal—perfect for outdoor workouts.

• Bass that motivates — The dual-chip single unit (main + headphone amp) drives a larger 14.2 mm speaker for dynamic, energetic sound.

• Comfort that lasts — Soft silicone ear hooks with titanium memory wire hug your ear comfortably and stay put during sprints and HIIT.

• Less sound leakage, more privacy — The independent cavity and directional conduction focus audio toward your ear.

• Crystal calls — High-sensitivity mic with intelligent noise reduction keeps your voice front and center.

Care & FAQs

Q: Are these bone-conduction?
A: They’re OWS (Open-ear Wireless Stereo) using directional air conduction, not bone conduction—so you get openness with a more familiar dynamic-driver sound.

Q: Can others hear my music?
A: At normal volumes, the independent cavity + directional conduction helps reduce leakage; very high volumes may still be faintly audible nearby.
