True Wireless Bluetooth Noise Cancelling Headphones

Noise-canceling headphones are a must-have product for office workers.
 
First, noisy environments often affect what we focus on, and efficiency will be greatly reduced.
 
Second, when using ordinary headphones in an office environment, In order to suppress external noise, the volume will be relatively loud, which will damage the auditory hair cells in the cochlea and is irreversible.
 
Besides, after the external sound is isolated by noise reduction, the world is quieter and the music in the ear is relatively purer.
 
   
 
1. Headphone noise reduction is divided into passive noise reduction and active noise reduction.
 
The principle of passive noise reduction is the same as plugging the ears with cotton. The in-ear silicone plugs on the earphones and the earmuffs of the headset can provide the noise reduction effect.
 
Active Noise Cancellation (ANC) collects the external environmental sound through the microphone of the headset, and generates a sound that is opposite to the environmental sound in real time to cancel the environmental sound, so that the music you hear will not be affected by the external environmental sound.
 
Therefore, the shape of the headset product also has a significant impact on noise reduction.
 

 
2. The noise reduction effect of in-ear noise reduction headphones is the best.
 
Active noise reduction mainly filters low-frequency sounds, and the in-ear silicone sleeve on the headphones can physically shield some external high-frequency noises, which is natural from the sense of hearing. It's better. But at the same time, the silicone sleeve will also cause pressure on the ear canal, and it will be uncomfortable to wear it for a long time.
 
Semi-in-ear true wireless Bluetooth headsets will be much more comfortable, but because they are not close to the ear canal, external noise will still enter the ear canal, the noise reduction effect will not be so obvious, and the sound quality will not sound In-ear style is so pure.
 
3. Bluetooth 3.0 and above can provide qualified sound quality experience.
 
True wireless Bluetooth headsets transmit data through Bluetooth transmission. Before Bluetooth 3.0, the sound quality was limited by the data transmission bandwidth, and it could only support formats with small data volume and greater loss of sound quality.
 
After Bluetooth 3.0, the bandwidth of Bluetooth communication has been able to meet the needs of high-quality music.
 
The current Bluetooth 5.0 has been able to provide enough bandwidth to provide a higher sound quality experience.
