• Professional ANC Technology: it's a combination of feed-forward and a feed-back ANC system. Active Noise Cancellation uses noise-canceling microphones and speakers to reduce unwanted background and surrounding white noises, which suits our commute and enhances our quiet relaxation time

• Upgrade Bluetooth 5.0 Headphones: they are extremely easy to connect to our phones, we can also listen to music via the long 3.5 mm auxiliary cord if they run out of power. Built-in omnidirectional CVC8.0 noise reduction microphone is good enough for our business calls, the voice quality is great and relatively well balanced

• Comfortable Over the Ear Design: the earpads of our Mixcder headphones are well cushioned, like leather air pillows. The ergonomic over-ear design is perfect for our average head shape, with slightly larger ear cups that cover our ears more completely, they are comfortable to wear even for long periods of time

• Matching Portable Travel Pouch: Mixcder E7 active noise cancelling headphones come with a drawstring bag that is space-saving and convenient. It would be the best choice for flying, they work on both low frequency noises and higher frequencies like human voices, helping us to better tune into our own musical world

• 50 Hours Battery Life: The Rechargeable battery provides up to 50-hour playtime in cordless mode when it's fully charged with included USB C charging cable. We can use these headphones for 7 working days, approx 7 hours a day to cancel unnecessary noise in the workspace, the whistle of cars and the mechanical sound of the subway running during our commute
