Advanced Noise Cancellation Technology: Maintain your focus with hybrid active noise cancellation. Dual noise-detecting microphones pick up and filter out up to 95% of low-frequency ambient sound to ensure nothing distracts you from your music. Ultimate Noise Cancellation Experience: Customize noise cancellation with 3 modes—Transport minimizes airplane engine noise, Outdoor reduces traffic and wind, and Indoor dampens the sound of busy offices with people talking in the background. Hi-Res Music: Hear every detail of your favorite songs thanks to 40mm drivers. The highly-flexible silk diaphragms reproduce thumping bass and crisp treble that extends up to 40kHz for improved clarity. 50-Hour Playtime: active noise cancelling headphones play up to 50 hours of music in noise cancelling mode. Standard mode extends the playtime to 60 hours, while a short 5-minute charge gives you 4 hours of listening. Pressure-Free Comfort: active noise cancelling headphones have ultra-soft protein leather earcups with memory foam padding to fit snugly over your ears. The lightweight build also ensures they’re comfortable for long listening sessions. TCO Certified: For Better Sustainability. Note: ANC is not compatible with an AUX Cable connection.
