With Bluetooth technology developing rapidly, there are many bluetooth products on the market nowadays. A Bluetooth headset is one of the most popular Bluetooth products. It lets you free yourself from wired headphones, loved by so many people that it’s almost a fashion statement. Then what are the benefits of using a Bluetooth headset? Let’s look at them in this article! The Bluetooth headset is not only a wireless headset, but also has more functions. So on the occasion of this hot season, what are the advantages of using Bluetooth headsets? Come and find out with us.
Noise-canceling headphones are designed to reduce or eliminate ambient noise by using active or passive noise cancellation to create a neutral sound environment. This type of headphone has two types – active noise canceling and passive noise blocking. Active noise canceling is achieved by generating reverse sound waves that are equal in amplitude but opposite in phase to the first three or four unlabeled frequencies (for instance, 100Hz and 120Hz), which cause the total amplitude of the combined signal to be minimized when this signal is played back over air. Passive noise reduction relies on a physical barrier between the user's ear and external sounds — such as earmuffs mounted on headphones — to prevent surrounding sounds from entering the ear canals (as opposed to active noise cancellation, which creates an internal sound field that counteracts outside sounds).
