First of all, thanks to worth buying, thanks to Zhang Aunt, and thanks to the source products provided by Shengyuan Technology Co., Ltd., and knowing that Zhang Damo has indeed achieved a lot this year. Not only is there a full range of special product recommendations, but also original and measured. The article in the channel to learn shopping knowledge, will not suffer a loss from shopping, Zhang Aunt feel this boat is very worth, this time I am lucky to get Aunt Zhang's patronize, have the opportunity to evaluate this linner (listen) active noise reduction Headphones, first let's find out what is active noise reduction.
There are two ways to reduce noise, active noise reduction and passive noise reduction. The so-called active noise reduction is through the noise reduction system to generate the reverse sound wave equal to the external noise, neutralize the noise, so as to achieve the effect of noise reduction.
In fact, every day mobile phones used by people also contain active noise reduction. The internal noise reduction microphone on the top of the phone or on the back of the phone collects active voice noise by collecting noisy sounds in the call environment, thus transmitting a clear voice.
The working principle of active noise canceling headphones Baidu learned that it is probably completed through the following steps:
1. The low-frequency noise in the environment that can be heard by the ear is first detected by the signal microphone placed in the earphone.
2. The noise signal is then passed to the control circuit, which controls the circuit for real-time operation.
3. Cancel the noise by emitting a sound wave that is in the opposite phase of the noise and with the same amplitude, so the noise disappears and is inaudible.
Active noise canceling headphones on the market are expensive, and the price of good quality is usually more than a thousand dollars. Today's leading linner active noise canceling headphones have achieved very close to the people's price whether they are crowdfunding prices or normal selling prices. Rarely, such prices are presumably for most consumers who want to experience active noise canceling headphones. Then how is the actual performance of this headset? Below, I will take everyone to understand it.
The courier box sent by Zhang Da Ma came with a sealing tape, which was printed with eye-catching values ​​that were worth buying LOGO and was affixed with a seal. The packaging was intact and was not subjected to any violent squeezing.
Linner headset box, the volume is relatively small, in addition to the front of the product promotion map and similar bat logo brand LOGO outside the entire package without any product model and parameters introduced, it is too simple, but fortunately the hardness of the box is good , can play a very significant role in the collection.
The drawer design used in the packaging box can pull out the inner layer horizontally. There is no other brand LOGO on the front side of the inner packaging box.
When you open the lid and find that the headset is covered by a semi-permeable paper, it may be to enhance the user's joy and sense of mystery.
The earphone is firmly fixed on the black sponge, which can prevent the loosening during transportation. In fact, this placement is very reliable. However, the manufacturer sticks the earplug with glue in the groove to make it more secure and remove it. It takes a lot of effort to use the headphones, and the cancellation of the earphones will also have sponges on the earbuds, which will bring unnecessary trouble to the users. I hope the manufacturers can improve them.
The lower part of the box is the accessories box. All the earphone accessories are filled in. There is a button hole on the accessories box for easy removal.
In general, the packaging box still lacks a sense of design and high-end quality. It is hoped that the manufacturers will be able to make the box more elaborate. Some of the basic parameters and the factory information printed on the product may be better.
This linner active noise canceling headphones have a total of three color combinations, namely Jazz Blue, Flaming Flames and Champagne Gold. Jazz Blue gives people a feeling of a bit of fanfare. Flaming Flames gives a strong sense of movement and I receive Champagne gold is even more stylish.
Let's take a look at what the accessory box contains. Open up and see there is a beautiful imitation leather storage bag, a manual, two pairs of earplugs, a pair of ear hooks, a charging adapter, also from the richness of the accessories not bad.
The snap closures used in the imitation cowhide storage bag are good, the snapping force and resistance of the snap button are good, and the inner suture used in the storage bag ensures its aesthetic appearance.
Let's take a look at the various accessories in the bag. The headphones accessories are all white.
Charging adapter, at first I thought it was a card reader.
Two pairs of earplugs of different sizes, plus a total of three pairs of headphones, fully meet the needs of different ears.
Supplied spare earhook, the material is very soft, the actual use is also awesome, basically does not appear to fall, after reading the accessories and then look at the main body of the headset.
Headphones mainly include earplugs, 3.5mm plugs, headphone cords, and function modules. The headphone cords are external to the TPE and are high-purity oxygen-free copper wires. Because the function module is integrated in the headphone cable, high-end players cannot try to change the line. The price of the headset is not necessary to change the line, and the wire quality is also good, durable and not easy to yellow.
3.5mm gold plating plug, because the headset can answer the phone, compared to the pure music headphone connector more than one circle, the plug tail and the headphone cable connected to the location of the protection of the loss of plastic reinforcement, try compatibility, Iphone and Android phone You can call and listen to music normally. There is no problem with the player.
The microphone used for the headset is integrated into the line of the right earbuds and can be worn just in front of the mouth to make the call clearer.
The outermost layer of the headset is a champagne-colored aluminum alloy cover shell, concentric circular corrugated circle is clearly visible, the outer ring CNC high-light trimming, the metal texture is good, but the earphone cavity polycarbonate material pulls the low value and grade, with The benefit is that winter does not feel cold.
The earphone uses a common moving coil speaker unit. The sound hole is not a common circle but an oval shape. The elliptical metal filter is visible from the outside, and the details of the process are still relatively meticulous. The lateral elliptical earphone hole with soft and comfortable earhook can well ensure wearing comfort and reliability.
The function module of the earphone is set at the sub-line. It is also made of metal material. The thin and thin sheet shape can effectively avoid the trouble of walking the whole earphone when it is walking or running, and it will not increase the burden of the line. The front circular button is responsible for controlling the music playback and telephone answering of the mobile phone. The toggle switch on the side is responsible for the noise reduction/monitoring function switch, along with a status indicator on the side.
Since it is a functional noise reduction headset, take a look at its specific parameters:
The line-control operation of this active noise canceling headset is very simple. The round button on the front of the function module is responsible for answering the phone and music playback (click to pause, press the next two times to play the next one), and the left side of the function of the paddle M file open monitor function, right slide A file to open the noise reduction function.
The elliptical earbuds and the soft earhook support greatly increase the firmness of the amount fixed in the ears. In the three-hour experience, the feeling of guilt brought about by the common earphones is almost not felt, so it is comfortable. Degree can still be recognized. The stethoscope effect is also controlled to be relatively small.
Here to talk about my subjective sense of this headset, and honestly I do not report too much expectation on the performance of this main feature-type active noise reduction headphones sound quality, after the actual audition to feel its sound and tuning style The overall performance of the tri-band was more balanced and there was no prominent place. The performance was slightly flat. The texture of low frequency is a little scattered, but fortunately, the speed can be downgraded; the texture of the intermediate frequency is relatively mellow, structured, high frequency is not too obvious features, sound is not convex or concave, knot image distance is moderate. This price level of active noise canceling headphones can actually achieve this level already valuable.
4. Noise reduction effect
Noise reduction is the highlight of this headset, although the complex external environment noise after noise reduction can not be completely eliminated, but the isolation of low-frequency noise is still very obvious, for me this day to push bus subway hardships Young people benefited quite a lot, and the noise from subways and bus stops disappeared almost as if they were enchanted.
At the same time, the noise reduction stability is very good. You really have a feeling of quiet in the world, and you can finally listen to the music in a quiet and quiet manner. In the case of active noise reduction, the overall sound field of the music is magnified and the details are better, but there is still a slight noise floor but it does not affect the use.
5. Listening purpose
This headset also has a monitoring function, a bit similar to the effect of hearing aids, after the opening of the ambient sound is obvious, listening to songs on the road to ensure safety, but the surrounding noisy sound will also be in the ear, the use is not too big, I think this function is the most practical The scene should be that the office is doing good for the ears, listening to a certain colleague whispering, talking about what stocks can make money.
Different from similar products on the market using AAA batteries, the noise reduction module of this headset has a built-in 20 mA rechargeable lithium battery. The indicator light is red when charging, and the indicator light is green when fully charged. Customer service says that the indicator light will show yellow when it is used for charging (only support Huawei P8, P9, Mate7, Mate8), if the ordinary mobile phone headset power supply can provide better charging, no electricity must use special adapter to provide charging, Fortunately, even if you don't have an electric earphone, you can work normally, but you don't have the noise reduction and monitoring functions. It takes about 1 hour to fully charge the battery, and the battery life is measured and advertised. It takes about 4 hours.
1 price close to the people, 399 yuan will be able to experience the charm of active noise reduction headphones, crowdfunding price is 199 yuan against the sky, the purchase entry threshold is indeed very low, for those who love the Bose noise reduction headphones and shy friends in the bag It's a good choice.
2 Although there is still a gap compared to the high-end products in the industry, the effect of active noise reduction is obvious. No matter how you take the bus or the subway, you can feel comfortable listening to music or watching the drama without being affected by the noisy environment. .
3 The structure is well-designed and comfortable to wear. The most important thing is not to feel tired like a clip-on ear or a hook-type earphone, but it is more reliable than an ordinary ear-plug. Even slight movement will not fall.
4 Although the monitoring function is not very useful, but not to mention tasteless, not only to ensure safety when listening to songs on the road, in the office along with a few people talking about the stock is also good.
insufficient1 The performance of the sound quality is normal, but it is not a good thing. However, it has not achieved a good level. After all, the product price and functional positioning are there.
2 battery life is only about 4 hours, taking into account the lightness of the headset at the expense of endurance can be described as fish and bear's paw can not be both, only support a few of Huawei's mobile phone direct charge, a little regret, hope that the follow-up products can support more Multi-model.
3 The packaging design is too conservative. I hope that the manufacturers can improve the texture of the packaging.
The rechargeable sealed Nickel Metal Hydride (NiMH) cell absorbs hydrogen in the metal alloy makeup of its negative electrode during charge. As the cell is discharged, the metal alloy releases hydrogen to form water.The use of the metal alloy is the underlying reason for the high energy density of the NiMH cell compared to other chemistries. NiMH batteries have a long cycle life and good storage characteristics.
