Enjoy Personal Space Anywhere: Low, mid, and high frequency noises are individually targeted by the 3-stage noise cancelling system. Hybrid active noise cancelling reduces low-frequency sounds like airplane engines and traffic noise by up to 98%. The other 2 stages filter out mid and high frequency noises such as crying babies and barking dogs. Ideal for Long-Haul Flights and Traveling: Up to 50 hours of playtime in noise cancelling mode will easily cover a vacation, an around-the-world flight, or weeks of commutes. In normal mode, you'll get up to 65 hours of listening, and if you run out of power mid-journey, a 5-minute fast charge gives you 4 hours of playtime. Tailored Noise Cancelling Response: Adaptive noise cancelling detects external noises around you and automatically adjusts to different tailored modes.
