With multiple NC functions, you can choose the appropriate mode depending on the occasion. The Transparent Mode is ideal for walking or running, allowing you to hear ambient noise to be fully aware of your surroundings. The Outdoor Mode is the perfect choice for cyclists, as it reduces wind noise. Full-on noise cancellation, on the other hand, is the most versatile, working well in busy subways or other typically very noisy places. Additionally, the very easy mode switching, by double-tapping the left earbud, allows you to quickly change and adjust the earbuds to the current situation.
