Which countries patent noise reduction technology?

Speaking of TWS headphones, with the real wireless and unconstrained wearing experience, we have begun to subtly change our habit of using headphones. However, in the face of the dazzling TWS headset brands on the market, how can we choose a wireless headset that really suits us?

In fact, whether a real wireless headset can be recognized by consumers can be known from its sales. For example, the FIIL headset brand founded by teacher Wang Feng across the border will be out of stock almost every time a new product is sold. Take the dark gray version of FIIL CC Pro launched in April as an example. It has been out of stock for three times when it was sold, and the user's recognition is really self-evident.

Why do people have such a high recognition of the FIIL headset brand? In addition to the unique design, FIIL true wireless headphones have a very good performance in configuration and experience. On the newly launched FIIL CC Pro, FIIL exclusive breathing light, dual noise reduction, Bluetooth 5.2 and 30-hour battery life are added.

On July 16, the pre-sale of FIIL CC Pro ceramic white officially began. If you want to know more about the use effect of this FIIL true wireless headset, here I will also bring you some hands-on experience about FIIL CC Pro ceramic white.

Every TWS headset is equipped with a storage/charging box, and FIIL CC Pro is no exception. The surface of the box is painted with white gloss piano paint, which is round and compact and comfortable, which brings great convenience to the storage, charging and carrying of headphones. The English logo in the middle of the box is the exclusive breathing light of FIIL, which will flash when it is opened or charged.

The storage/charging box of FIIL CC Pro adopts the design of Type-c charging interface. At the same time, the charging box supports fast charging function and is compatible with mobile phone adapters. Usually, you can charge directly by using a mobile phone adapter that supports fast charging, and it only takes about 1.5 hours to fill the charging box and headphones.

Of course, it is worth mentioning that the charging box of FIIL CC Pro also has a built-in wireless charging module. In addition to charging through the Type-c charging interface, it also supports charging with a wireless charger. Without the bondage of charging cable, charging headphones is between taking and putting.

Thanks to the support of FIIL CC Pro charging box and the dual fast charging function of headphones, after the headphones are turned off at low power, we only need to put the headphones in the fully charged charging box for 5 minutes, and then take them out to continue listening to songs 1 hour. Of course, when not in use, it only takes 50 minutes to fill the earphone in the charging box, which is really good for fast charging.

Regarding the battery life issue that everyone is most concerned about, FIIL CC Pro headphones can listen to music continuously for 6.5 hours after being fully charged. If the charging box is fully charged, you can add an extra charge of about 3.5 to the headset. The measured battery life can exceed 30 hours. In other words, if you listen to music for 4 hours every day, you can basically meet your needs of listening to music for a week by charging it once.

In the design of headphones, the body of FIIL CC Pro cuboid can be said to subvert the inherent form of real wireless headphones, and the metal texture and rectangular body present a tough sense of lines. Of course, this is also one of its most attractive places. In addition, the color scheme of this ceramic white looks higher than that of the deep space gray sold before. what do you think?

The cavity shell of FIIL CC Pro is ergonomically designed. When wearing, the cavity will be firmly hung on the outside of the ear canal to improve the stability of the earphone when wearing. At the same time, a wearing sensor is added to the cavity shell, which can detect the wearing state in real time. When the earphone is taken off, the concert will be suspended, and when it is worn again, the concert will automatically resume playing, without taking out the mobile phone to operate, which improves the experience of using the earphone.

In terms of earphone control, FIIL CC Pro adds capacitive touch keys to the cavity shell, and both ears can operate independently. In standard mode, tap the left earphone/right earphone twice: music plays/pauses, and calls are answered/hung up; Press and hold MAF for 2 seconds to switch/reject incoming calls.

After talking about the appearance of headphones, let's briefly talk about FIIL CC Pro's exclusive APP FIIL+, through which you can unlock more hidden functions of headphones.

APP FIIL+ can not only check the power of FIIL CC Pro headphones and charging box, but also set different listening styles in FIIL+, including nostalgia, jazz, light music, cinema, heavy metal, etc., in addition to regular bass, soundtrack and treble. Of course, there is also the switching of MAF noise control system, but it can also be switched by capacitive touch keys on headphones.

Of course, it is most worth mentioning that the low-delay mode of headphones can be turned on through the exclusive APP FIIL+, which supports the switching of three different modes: game mode, music mode and video mode. When playing a game, choosing the game mode will get an ultra-low delay sound transmission speed of 70 milliseconds, which will improve the synchronous transmission effect of sound and picture in the game. In addition, you can turn on the universal control mode, increase the volume adjustment of headphones, and switch the touch operation of songs.

In connection, FIIL CC Pro adopts the latest Bluetooth 5.2 connection technology, which has greatly improved the connection speed, stability and anti-interference. After the headset and the mobile phone are successfully paired for the first time, when the headset leaves the cover of the storage box, it will automatically connect, and the experience is quite good.

In the aspect of active noise reduction, it is equipped with FIIL patented technology MA intelligent noise modulation system, and adopts double noise reduction microphone design and ANC noise reduction technology. Hybrid active noise reduction consists of feedforward noise reduction and feedback noise reduction, which can weaken about 98% of environmental noise. I also had a noise reduction experience when I took the subway to and from work. Switching FIIL CC Pro to active noise reduction mode, I can feel that the noise in the noisy carriage is obviously reduced.

At the same time, FIIL CC Pro also adds ENC call noise reduction technology, and schedules three microphones to work together during voice call through intelligent algorithm, which can accurately identify noise, wind noise and human voice in the environment and weaken environmental noise, even in noisy environment. The caller can also hear his voice clearly.

On the delay mode that the mobile party is most concerned about, I used Peace Elite to simply test its performance in the synchronization of sound and picture in the game. In the test, shooting at the ground with a gun, from hearing the gunshot through headphones to seeing the bullet marks of the gun hitting the ground, can be said to be almost synchronous. For users who like to listen to songs and play mobile games with headphones, FIIL CC Pro is really a wireless headset worthy of recommendation.

In terms of sound quality, FIIL CC Pro adopts a pair of 10. 1mm wool basin composite diaphragm units. This composite diaphragm unit made of pulp and wool fiber can make the speaker both elastic and tough, and even the smallest energy can respond accurately. When listening to the tracks played by some musical instruments, it can present crisp and pleasant musical instrument details, giving you an immersive auditory feast. In addition, its three-frequency balanced tuning is very pleasing, and its deep voice can also give people a full and rich feeling, with obvious layering and strong sense of encirclement; The intermediate frequency has a very comfortable feeling, and the overall performance of the voice is quite clean, which can fully meet the needs of listening to music and playing games when I go to work and the subway.

Whether listening to music, watching videos or playing games on mobile phones, we are all used to the wireless binding experience brought by real wireless Bluetooth headsets. Today, real wireless Bluetooth headsets are everywhere. FIIL CC Pro ceramic white version enhances the value of real wireless Bluetooth headsets through its unique design and brand-new color matching. The addition of dual fast charging and wireless charging improves the charging experience of headphones, as well as Bluetooth 5.2 technology, low delay mode and ENC dual microphone call noise reduction blessing. It can be said that whether listening to music or playing games, FIIL CC Pro has brought a very good listening experience.
