to subvert the cognition of the old burning friends?

has long been a synonym for Sony and Bose's products. Other products on the market rarely appear in the life circle of new audio and video. In fact, after experiencing such products, the new audio and video summed up a point of view, other brands of noise reduction products are either inferior to these two products in terms of wearing, sound quality and active noise reduction ability, or the price is too high to affect the decision-making. Many of our domestic audio brands are very powerful manufacturers. Feiao brought his new headset EH3 NC to blow up the circle of friends of new audio and video. At that time, seeing all the bosses basking in the pictures of this product has already given the new audio and video the impulse to give it a try.

in the past, Feiao gave us the traditional impression of a player manufacturer. Their products are famous for their outstanding cost performance and rigorous sound quality. Since testing earphone products in the past few years, Feiao has not stopped its own research and development, and there have been many surprises in earphone products. If the new audio and video are not mistaken, EH3 NC should be Feiao's first headset product. Although it is the first time to come into contact with Feiao's headset products, the "familiar" feeling has been felt since the moment I saw the packaging.

yes, it is the familiar powerful function and fine product workmanship. If you don't look at the storage bag, this time Feiao has prepared a Type-C charging cable for EH3 NC (which can be directly connected to the computer using USB DAC function) and a traditional 3.5mm wire.

from the aesthetic point of view of new audio and video, although EH3 NC's products are very delicate, 2.5D carbon fiber glass, high-light tie rod joint, silver metal visual earphone frame and large area covering the head of the protein cortical head beam constitute a rather complicated visual effect. EH3 NC is cool from various angles, but it is essentially different from the current large factory products that pursue unified elements. Feiao's products look more modern, professional and technological. Although some fashionable and unified elements are missing, looking at the appearance of domestic headphones, EH3 NC is more representative and is a very outstanding kind of product.

wearing is a very important attribute of noise-canceling headphones. Whether it is for hearing protection or meditation, long-term wearing is a place where noise-canceling headphones are different from music headphones. EH3 NC is regarded as a benchmark in domestic headset products. Although it has a relatively "bloated" appearance, it is still quite good to wear. Especially the pressure of the head beam is very small. The cortical earmuffs are thick and deep, wrinkled, and breathable. At present, the city where the new video is located belongs to a coastal city in the north. The temperature in the afternoon is about 19 degrees, and there is no sultry feeling in the ears. However, Feiao also seems to consider the problem of wearing this earmuff in summer. The part of this earmuff can be disassembled freely, and users can purchase breathable mesh earmuff. The first pre-sale users are said to receive this breathable mesh earmuff on the drying list.

headphones is concentrated on the right, and users who have used Bluetooth headsets can get started quickly. Without the strange gesture operations of Sony and bose, returning to this honest button has quite a feeling of using iron triangle headphones. Here EH3 NC supports direct connection of 3.5mm interface wires, and the earphone switch function fails at this time. If users want to use active noise reduction, connect Bluetooth honestly or use USB Type-C cable to connect headphones. In other words, the noise reduction mode can only be enabled when the headset is receiving digital signals.

In terms of noise reduction, in addition to thick earmuffs for passive noise reduction, EH3 NC has four microphones (two inside and two outside) for receiving noise signals. According to Feiao, the noise reduction chip uses ADI's ADI1777 x2 chip. The actual effect is said separately after the new video.

EH3 NC is one of the few earphones that support NFC direct pairing. With NFC Bluetooth pairing, it is as simple as linking the earphone wire. You can complete the pairing by touching the NFC antenna. EH3 NC supports full format on Bluetooth codec and uses a CSR8675 chip. The new audio and video here focuses on LDAC and AAC codecs.

sound, the new audio and video have been cooking this earphone for about 40 hours, and the sound feeling has not changed much. However, the difference between using Bluetooth and wired connection and whether to turn on noise reduction sound is obvious. Since there is a certain difference between using Bluetooth and using wired connection, I 'd like to talk to you separately. The wireless connection is mainly based on the use of LDAC for M11 to connect EH3 NC via Bluetooth, while the wired connection is mainly based on the original line and the ancient river upgrade line purchased by the new audio and video long ago, with the 3.5mm single-ended output of M11.

Bluetooth should be the most common way for EH3 NC. In the past few years when the headset interface was canceled by iPhone, Bluetooth audio products have developed rapidly. However, concepts such as LDAC and Bluetooth 5.0 are often blown up by manufacturers. In fact, the sound quality of Bluetooth products is affected by the codec (transmission formats include: LDAC, AAC, aptX, etc.) and the audio decoding/amplification capability of the headset itself. Whether it is Bluetooth 5.0 only has a certain degree of influence on Bluetooth experience. Different from ordinary Bluetooth earplug products, headset Bluetooth earphones have more space to arrange antennas, amplification circuits and batteries, which will be easier to design, so manufacturers can unscrupulously accept wireless signals and amplify analog signals after processing.

the sound of EH3 NC this time is very dynamic. The loose dynamics and lively low-frequency and high-frequency processing left a deep impression on the new audio and video. If you are a pop music lover or a movie lover, this product can provide a pretty good audio and video experience. The sound characteristics of EH3 NC under AAC are more obvious, but the sound under LDAC will be neutral and loose, and this vivid sound attribute is very modern, transparent and popular. Judging from this characteristic, EH3 NC is not a rigorous product for enthusiasts who pursue perfection first, and this is more prominent on 3.5mm wire.

next uses a 3.5mm cable, which is different from the products of many major international factories. The sound of using a 3.5mm cable is very different from that of using Bluetooth, and using a traditional cable will obviously crack the sound. However, EH3 NC will not do this. It basically retains the sound provided by Bluetooth, strengthens the bass and emphasizes the "three-dimensional effect" of the sound. Because of the different connection methods, it may also have something to do with the output of M11. Feiaote is equipped with a 45mm large unit for EH3 NC. If you want to experience the layering and analytical power of sound, you still need to use wired connection.

original line is very abundant, and the sound sense is to take the route of high-frequency and low-frequency. Compared with Bluetooth, the resolution is obviously improved, and the sound field has a more relaxed experience, thus shaping a solid image and a more three-dimensional sound texture. If you switch to other wires, such as the ancient river line with relatively balanced sound in the new audio-visual hand, the intermediate frequency density will immediately increase, and the whole sound will also have a more balanced and transparent sound experience. In addition, the dynamic range of the headset itself is good, which can show that EH3 NC can achieve the following grams by changing the line.

interesting is that users can use C to C USB Type-C wires on products without 3.5mm interface, so that the player or mobile phone can use digital output. The sound obtained at this time is also the sound processed by the set of audio in the earphone. However, the difference between wired connection and Bluetooth is relatively small, not as big as the difference between 3.5mm interface, and the difference is the largest, the new audio and video think it is whether the headset is turned on to reduce noise.

, in terms of sound quality, when the user turns on noise reduction, the sound of EH3 NC seems to be covered with a layer of yarn. Because noise reduction headphones will make up for the sound quality loss caused by noise reduction through algorithms, while EH3 NC's compensation algorithm in low frequency and medium frequency parts is more prominent, and the sound seems to have lost part of its "vitality". Let the sound quality slightly decline, but the listening sense is more moderate and balanced.

However, judging from the noise reduction effect, EH3 NC can cope with most of the low-frequency noise, which can almost match the MDR-1000X of Sony's first generation head-mounted noise reduction headphones. For medium and low frequency noise processing, EH3 NC can reduce noise well through passive and active combination. The noise reduction EH3 NC in other frequency bands is slightly inadequate, such as noisy vocals and sharp high frequencies. Although some of these can be filtered out by earmuffs, in terms of actual experience, EH3 NC has not yet reached the level of Sony WH-1000XM3 and Bose 700 headphones. However, what is exciting is that as the first show of Feiao's headset, the noise reduction experience obtained at a relatively reasonable price has almost subverted people's understanding of domestic noise reduction headphones.

the detailed setting of headphones needs to be adjusted in the software, which is also the practice of many big brands to conform to the current people's usage habits. EH3 NC supports Bluetooth control of Feiao Music, and can adjust and set EQ, display status and power saving mode.

new audio and video write more content about Feiao's products every time, which also reflects the characteristics of Feiao's products, which pay attention to the overall feeling and experience of users guided by sound. For users who need noise reduction and like portable headset products, this product is still worth reference. EH3 NC is a typical Feiao product, attracting users to get to know him deeply with its outstanding cost performance and outstanding selling points. Although EH3 NC is not a headset that can match the contemporary flagship experience of Sony and Bose, the excellent cost performance, excellent functional design and comfortable wearing leave a very deep impression on the new audio and video.

, if you don't consider the extreme noise reduction experience and like portable headset products, you can try EH3 NC. In particular, the 3.5mm line change method gives the new audio and video a new understanding of this product. Or EH3 NC is still a sound quality earphone. Since it comes with good noise reduction function and full format Bluetooth function, there seems to be nothing to pick on.
