Active noise canceling headphones are no longer a new thing. The principle of sonic phase cancellation can effectively eliminate various noises such as cars and aircraft engines and the sounds in the environment. Although you can take the initiative to reduce noise, you can still quiet. However, outdoors, excessively strong sound insulation, it is easy to bring security risks, especially when crossing the road, if you can not hear the car whistle this will be quite dangerous.
Doer's Laboratory's Here One noise canceling headphones solve this problem. It can control the sound to be noise-reduced according to the user's needs, and retain the part that you want to hear. And this headset is a full wireless connection, not only the earphone itself. The transmission between Bluetooth and mobile devices, the left and right units are also connected via wireless.
Here One noise canceling headphones are very smart, Doppler Labs said that users can customize the headset in a very detailed way through a dedicated app, and can be optimized according to the user. Here One can keep the car whistle while filtering Other noise. In addition, some sounds can be amplified, for example, in a noisy environment, the vocals are highlighted to help the user hear the surrounding dialogue.
Don't think that Here One is doing this through a similar equalizer principle. Doppler Labs says that an adaptive filter is installed on the Here One to determine the type of sound and selectively eliminate it instead of The entire frequency band is completely removed. In addition, the headset also has a directional microphone, which can also eliminate or amplify the sound in a specific direction.
Here One's battery life is about 3 to 6 hours, which is relatively short among wireless headphones. But the Here One is small and powerful, so it is justifiable that the battery life is not good. Of course, Doppler Lab also thinks This problem, the headset's storage box has a built-in battery, you can always charge the Here One when you are not using it, you can make up for the short battery life.
It is reported that the Here One noise canceling headphones will be available in November this year, priced at 299 US dollars (about 1988 yuan). Active noise reduction headphones have not appeared to solve the safety hazards of outdoor use, and see After Here One, Xiaobian wants to say that this is finally able to go to the night with an active noise-canceling headset.
