TOZO NC9 Wireless Bluetooth 5.3 Headphones, Hybrid Active Noise Cancelling Earbuds with Deep Bass, Stereo In-Ear Earphones, 3 Microphones - White.

["Active Noise Cancellation"] Hybrid 3-layer Active Noise Cancellation. 1. An outward-facing microphone captures external sounds and combats them with equal anti-noise to first eliminate ambient noise. 2. An inward-facing microphone captures internal ear canal sounds and generates counter-noise to doubly neutralize the remaining noise. 3. Earcaps prevent 90% of noise from entering the ear canal. ["Transparency Mode"] With Transparency Mode, you can hear what you want to hear, allowing external sounds to penetrate so you can hear and interact with the world around you. You can clearly hear announcements from airlines or subways and everything being said around you without taking off the headphones. ["Built-in Dual Noise-Canceling Microphone"] The dual-microphone noise reduction system suppresses ambient noise. A dedicated internal and two external microphones pick up your voice and isolate it from external noise. ["One-Step Pairing"] Take the two earbuds out of the charging case and they will automatically connect to each other. Then simply perform one easy step to pair the in-ear headphones with your phone's Bluetooth, avoiding lengthy operations and saving time. ["On-the-Go Charging"] The TOZO NC9 wireless earbuds offer over 13 hours of playback time per charge and a total of 40 additional hours in the compact charging case. In active noise cancellation mode, they can provide over 7 hours of playback time. They offer convenient cable-free charging.
