Noise-cancelling headphones are a class of headphones that have been highly respected in recent years, especially active noise-cancelling headphones, which meet the needs of people listening to songs in airplanes or some noisy environments. Today we will experience this BeoPlay H3 ANC active noise canceling headphones are the first in-ear active noise canceling headphones launched by Danish audio-visual equipment manufacturer Bang & Olufsen in October this year. This BeoPlay H3 ANC basically continues the B&O non-noise-reducing BeoPlay H3 in-ear headphones. The biggest change in form factor and material technology is the addition of active noise reduction module. Compared with the non-noise reduction version of BeoPlay H3, H3 ANC with active noise reduction can better meet the needs of people listening to songs in different occasions.
Noise reduction mode audition:
The principle of active noise reduction is actually very simple, mainly through the anti-phase cancellation between the sound wave and the sound wave to achieve the purpose of noise reduction. The principle of active noise reduction is to first collect the waveform characteristics of the noise, and then calculate through the built-in processing chip. The inverted wave is cancelled by the high-reduction speaker. Therefore, the active noise-cancelling earphone has better noise reduction effect than the passive noise reduction, but such noise reduction usually comes at the expense of compromised sound quality. BeoPlay H3 ANC is committed to achieving the best balance between noise reduction, sound quality and quietness for optimum noise reduction.
　　 
In appearance, the BeoPlay H3 ANC and the non-noise-reducing BeoPlay H3 are almost the same. They still use the aluminum alloy casing and the metal brushed texture. They are not only light in weight, but also very strong and scratch-resistant. At the same time, they are full of metal and can give people A natural and calm feeling, this is also very similar to the BeoPlay series headphones style. There are 29 precision air holes distributed on the earphone housing, as the air guiding hole when playing music, can ensure the natural sound. 　　 
　　 
　　 
BeoPlay H3 ANC's noise reduction processing module is located above the 3.5mm plug. It has a round appearance, a skin-like coating on the surface, and a matte color. Thanks to the 350 mAh battery, it is comparable in weight to a normal earphone. Slightly heavy, but compared to up to 20 hours of battery life, such weight is more acceptable, endurance is also very prominent in active noise canceling headphones, in addition, even when the noise reduction module is out of power, Listening to music in normal mode, the sound insulation effect of the in-ear headphones is also good. There is also a three-button remote control microphone on the headphone cable, which is consistent with the non-noise reduction version of BeoPlay H3, which supports iOS and iPod lines. Control operation. 　　 
　　 
　　 
In order to better adapt to the needs of different users, BeoPlay H3 ANC provides users with four different sizes of earplugs for users to choose. The BeoPlay H3 ANC is also equipped with a Comply memory cotton earplug for more comfort. At the same time of wearing the experience, it also achieves the effect of enhancing the overall noise reduction. Active noise reduction + passive noise reduction can bring better noise reduction effect. In the use scene, BeoPlay H3 ANC can not only be used as an active noise canceling earphone. When the noise reduction module is out of power, it can still be used as a normal in-ear earphone. The accessories in the package include paper instructions, suede portable storage bag, aviation conversion plug, data cable and XS, S, M, L size silicone. set. 　　 
　　 
Before experiencing active noise reduction, let's briefly talk about the audition experience when the noise reduction module is not turned on. As the "noise reduction version" of the BeoPlay H3 headphones, it is natural to compare the two. The BeoPlay H3 ANC uses non-noise reduction. The same sound unit, but there are subtle changes in the tuning of the details. First of all, the measurement of the bass is obviously more, the performance of the bass is also better, the vocal part of the IF part is also very balanced, and There will be no slight chaos due to the bass. Secondly, in the resolution of the intermediate frequency, it is in a higher level in the dynamic headphones, and the sound is more stretched. The female voice and the male voice will show a tendency to be balanced, that is, everyone usually The sound is warmer and the sound is very good. It is very comfortable when listening to quiet type music. 　　 
In the high-frequency performance, the BeoPlay H3 ANC headphones have a frequency range of 20Hz-16000Hz, so its high frequency is limited, giving people an intuitive feeling that the sound is not bright enough, even when listening to some explosive songs. It will also give people a feeling of slight convergence, but this is also a major feature of this headset's high frequency, that is, the high frequency is soft and stretched, and the performance of dynamic sound is still very good. This also makes this headset give a very resistant feeling. Noise reduction mode audition:

As the main noise reduction function of BeoPlay H3 ANC, the first thing to say is that the active noise reduction effect of this BeoPlayH3 ANC earphone is very obvious. When the noise reduction switch is turned on, the measurement of the sound will be obviously improved. The noise from the outside world has achieved a good "blocking" effect, and almost no external sound is heard. The noise reduction effect is immediate. After using Comply memory cotton earplugs, the noise reduction effect is better, even if you talk face to face, you can hardly hear it. When used on the road, you can only hear the sound of the car whistle and the wind in the ear. The noise reduction effect on the ambient sound is very good, so it is not recommended to use the headphones when driving, and also pay attention to the choice when wearing outdoors. The environment, to avoid the danger of not being able to hear the surrounding environment. Perimeter LED Screen,Stadium LED Display,Stadium Advertising LED Display
