A Deeper Immersion Into Silence
The proprietary QuietMax technology and 3 high-quality mic structures provide up to 42dB of noise cancellation depth at a wider range of frequencies (40Hz-4000Hz). The noise canceling earbuds can block out more of the ambient noise no matter if it’s office chatter, city traffic or in-flight noise, bringing you peace and quiet.
