In this way, you can hear the sound picked up by the microphone in real time in your speaker or earphone. When you talk into the microphone, the headphones can hear a lot of sound. This is how announcers monitor their pronunciation when broadcasting.
How to wear headphones
The earliest earphones were two pronunciation units hanging on the ear, and later many kinds were developed, including earphones, earplugs, ear hooks and newly developed bone conduction earphones. Headphones are the earliest types of headphones.
Earplugs are a revolutionary breakthrough in the development of headphones, and the smaller size makes it very convenient to use outdoors. Due to the development of the city, the environmental noise is getting louder and louder. In-ear earplugs are a breakthrough in earplug products and are more suitable for outdoor use.
Earhook can be regarded as an intermediate product of earphone and earplug. The characteristics of the ear hook neutralize the advantages and disadvantages of headphones and earplugs, and belong to a product with unclear characteristics, but it is very beautiful to wear. Bone conduction earphone is a relatively new technology, which uses the principle of vibration to transmit sound directly to the listening center through the skull. However, this product has not been popularized, and it is still unknown whether it can bring revolutionary breakthroughs to headphones.
