Jabra Elite 75t do not supports active noise cancelling
The Jabra Elite 75t earbuds adopt 4-microphone call technology, employing mic on the outside to block ambient sound and a second mic on the inside to deal with whatever leaks through. That can making and taking calls is always a great experience. In addition, thanks to enhanced 4-microphone call technology, which filters out disruptive noise around you, even in noisy and windy environments.
However, there is no active noise cancelling (ANC) equipped in the Jabra Elite 75t TWS, but the passive noise cancelling (PNC) technology. What’s passive noise cancelling and what is active noise cancelling?
ANC VS PNC: which is better?
Active noise cancellation is a noise reduction technology, which is one of the methods applied to headphones to reduce noise. noise is collected through a microphone, and then a series of software and hardware algorithms calculated and designed by acoustic engineers are generated by circuits from reverse sound waves with opposite noise. It is emitted through the loudspeaker, and eventually the noise and the reverse sound wave cancel each other out.
Advantages: ANC can eliminate the background noise with low frequency, and has a good de-noising effect on the environment.
Disadvantages: the denoising effect of high frequency is poor.
Passive noise cancellation depends on the shape of the cavity, and sound-absorbing material (such as in-ear headphones), or earmuffs are attached to the ear canal to isolate the inner ear sound from the external sound. to put it simply, the headphones use sound-absorbing material. To reduce the external noise to a certain extent.
Advantages: can greatly reduce high-frequency noise.
Disadvantages: for some low-frequency noise, the role of sound-absorbing materials is very limited.
In terms of noise reduction and sound quality, the sound quality effect of passive noise cancelling headphones is better, because the active noise cancelling headphones have obvious traces of sound processing, and most of them take noise reduction technology as the selling point and do little in sound quality.
On the other hand, the noise reduction performance of passive noise reduction headphones is determined by the way they are worn and the structure of headphones, from low-end to high-end models, the choice is greater, and the sound is more excellent.
Although the Jabra Elite 75t do not supports active noise cancelling, its sound quality is not inferior to that of AirPods Pro. Jabra Elite 75t VS AirPods Pro, which one would you prefer?
