What are noise canceling headphones? What's the difference with ordinary headphones? Want to know, come in and talk, let me know more.

The noise reduction principle of active noise reduction headphones is that a special noise reduction circuit is set in the headphones. Through the audio receiver (such as micro microphone) and anti-noise output chip, the frequency of external noise is received and analyzed, and opposite frequencies are generated, which weaken or cancel each other. The purpose of noise shielding can be achieved without adjusting the volume too much, providing users with a more pleasant listening experience. If the sound quality has any influence, it depends on the headphones. For example, QC3 of BOSE integrates TriPort acoustic structure, and the sound quality performance is still very good, with no influence at all. The sense of wearing is also the best among noise-reducing headphones at present, and the price is relatively high, which is suitable for people who have great demand for noise reduction on business trips. But if you are interested, you can go to the store for an audition, which is highly recommended.
