Noise reduction noise for the poor: Sony 750NA, Philips 8850NC, 3M earmuffs, Ohropax three earbuds

As an amateur network code word dog, although he wrote only a few pieces of flapping streets, but the code word dog should not have a few problems, but especially when the code word, is very sensitive to a variety of life noise Noise has also become a powerful excuse for I have not been able to become a god.

Because I have never been on Aunt Zhang. In fact, until last year, I learned that there are actually anti-noise headphones in the world. This has been the use of 3M noise earplugs and earmuffs to reduce noise.

3M earplugs, 10 yuan per year, 10 pairs, cheap enough,

Soundproof earmuffs, large and thick anti-human design, wearing a fool with two, really can not take out the door, not much use, only occasionally at home,

Later I learned that Ohropax, the boss of the so-called earplug industry, bought two boxes of soft series. Compared with it, no matter if it was comfort or sound insulation, 3M's earplugs were defeated.

Later, several kinds of domestically-made products were purchased, such as certain zero, one suitable, one excellent, and the like, and they could not be compared with Ohropax. From then on, they were fixed and used. Until now,

Saying that this brand is called ohrfrieden on the domestic electricity supplier, the Chinese name An Eryou, what is the relationship between ohrfrieden and Ohropax, I Baidu's result there is a kind of argument is that Ohropax has been registered in the country, so to enter China can only be renamed ohrfrieden, specific Did not really know it, but I have bought two, Ohropax is a friend brought back from the Netherlands, and ohrfrieden's comparison, it seems really no difference,

At present, there is only one last pair in the soft series.

Later, they purchased colorful series and wax pills series with better noise reduction effect from the same brand. The specific use effect will be explained below.

In addition to using it during the daytime work or codewords, because my home is a street building, there will be some noisy daylight, so I have developed the habit of inserting earplugs into my ears when they are not bright, so that I can feel eight o'clock. Certainly it was quarreled after more than six o'clock, and then one day when I was insomnia, wearing this only listened to my breathing, and I could soon fall asleep. It really has become an indispensable baby in my life.

Occasionally, I picked up a headset in an Apple store and wanted to study how it was so expensive (price 2800). After the introduction of the clerk, I realized that I was the active noise canceling headphone, and that I was just QC25, I tried it, and the clerk opened it to me. In the instant of the noise reduction switch, I believe that my eyes were bright at that time, just like entering the other world in an instant, completely isolated from the noisy shopping malls around.

From this heart, I learned the QC35, and soon I bought a pair.

Noise reduction effect as in the store trial, noise reduction can be said to be quite satisfactory, wireless is also very convenient, but also do not take the same trouble as earplugs, sound quality I am a wooden ear, this level of headphones for me too It is amazing, in short, it is almost a perfect noise reduction product.

In addition to the design of the QC35, it is the thick sponge at the top of the beam.

The position of the red coil in the picture,

There will certainly be many people who say that if there is such a thoughtful and rich humanistic sentiment and an increase in the design of wearing comfort, how can anyone still confess? !

I really didn’t want to shirk because the design may be good for 99.99% of people, but I’m at 0.011%, and it’s also a bit of a pain for me.

This is actually genetically related to our family. The male and head type of our family have a distinctive feature. The top of the celestial cap is not round, but slightly pointed.

Of course not very sharp, far from the deformity, as long as a little grow hair can not see it, but it is not really a round head, so this is even round head The design is extremely friendly, but it will really make my head feel alarmed. It takes less than half an hour to wear the time. The top of the head is like a hard object, and it is getting more and more uncomfortable!

I have tried various methods to improve comfort, including a little bit of awkwardness and comfort, but it is not easy to wear it and it is easy to fall. The second is that as long as the earmuffs and ears fit snugly, the QC35s all know that as long as there is a little air leakage, the entire noise reduction function has a "breaking power" feeling.

So insisted for half a year, finally reluctantly passed a salted fish to a local little brother,

Just used to noise-reducing headphones, in addition to sleep, the earplugs without music features earplugs have been unable to meet, is bound to buy a noise-canceling headphones, the target is still selected noise reduction industry BOSS,

Has visited QC25, QC20, QC30,

QC25 and 35 design, give up (just double 11 licensed only 900, ah, unfortunately)

QC30 I was shocked to get the hand, this plastic material, the glitches, this gap, the work is not at ease, right? Is this goods the same door as the QC35? After reviewing and commenting on the Internet, it seems very easy to open the plastic, so even if you catch up with the new egg, you only need to use 1.7 million copies of Zhang Damo, and hesitates to pay for it.

Qc20...... old products, have undergone market inspection, it seems pretty good, sound quality Well ... ... has never been my wooden ear considerations, that is, the price I see in previous years, the lowest price can be up to 1,200, usually they are maintained Two thousand lines, the lowest price of this thing, if you do not know okay, know it but buy expensive always feel like lost a few hundred million, coincides with the double 11 is near, ready to bear for some time until the good price on the

During the hearing, the MDR-1000X between Sony and QC35 broke down to 1399. When I waited for buying that night, I actually fell asleep!

Two more blinks naturally missed,

In the process, it happened to find the Philips SHB8850NC, Bluetooth wireless, also known as active noise reduction, to the price of 299,

During that time, I was in a noise-reducing earphone vacuum belt, and my heart felt itching. I thought it was not expensive. It would be nice to buy a machine for use in the office.

When you get the order, you will hear it after receiving the goods. Uh? Actually catching up with live, sound quality, listening to Cheeks and the like can make fun, noise reduction... really, plus it's pretty cheap, stay on, now just throw it in the office, take a call and watch a movie. , specific noise reduction will also be explained below

Still later, in the past just 11 pairs, qc20 actually did not engage in activities, WTF!

Jingdong is said to have a price of 1499, but I did not see it. I only saw it was out of stock, or two thousand.

On Taobao, it was a deposit, and it was inflated. Your sister was inflated and she didn’t even look at it. So the planned things were so shattered.

Also at this time, accidentally saw the Sony 750NA, as long as more than four hundred activities after the increase, quickly checked, usually sold 1199. Perennial eight or nine hundred, online and Aunt Zhang's value of friends said a lot of evaluation of this goods also Looks good, thinking that anyway, missed the QC20, and this goods is so cheap, even if you bought a bike that doesn't matter, it doesn't matter.

As a result, my hands had taken together the noise reduction six treasures of the poor, Sony 750NA, Philips 8850NC, 3M noise earmuffs, and three earplugs of Ohropax.

Objectively speaking, these are not perfect, they all have their own shortcomings, but also have their own advantages (in addition to 3M earmuffs), both different, also have a comparative value,

Before that, I just made two originals. I don’t know if I’ve been diving for a long time. Originally this stuff was really addictive, so even though it’s a bunch of bargains, I’m still trying to compare my ideas. For everyone to see, if you can help some valuable friends, it is the best.

Next, I will use a few more common scenarios, namely, bus, subway, street, high-speed rail, to compare the noise reduction skills, because there are also QC35 experience in the past six months, so it will intersperse some of the subjective feelings and QC35,

The first is a brief commentary and the subjective feelings of wearing.

750NA: Low noise, but it's not too big, especially when it's quiet, it's obvious that once you turn on the music, it's completely gone. The earbuds aren't designed very well. I'm often worried that I'll fall, though most of the time, It is not suitable for use in activities. Comfort Because I have the habit of plugging plugs all year long, this in-ear style is not a problem for me at all. I can wear it for hours and the sound quality is at least as good as Apple's original.

8850NC: Clear low noise, the same music can completely cover up, non-early ear clip design, but it will not squeeze the ears very hard to suffer, there is no sponge on the top of the head beam, this point has won my heart, no QC35 with For my discomfort, I can wear it for a long time. The price of the sound quality is not required, a word of satisfaction, almost the meaning than the QC35, but compared to the 750NMA, I prefer to use this goods to listen to music.

Ohropax's soft and colorful series, refer to an official website map,

Noise reduction on the bright series is better, the softness of comfort is better, I personally feel the same, it is difficult to tell the difference that is subtle, which is actually the same to buy, but colorful can be distinguished by color, this is an advantage ,

As for the wax pills, a thin layer of cotton is used to wrap a piece of sound-insulating wax in it. Before use, the cotton wool is torn off and the wax pill is stuffed into the ear. Note that it is not inside the ear hole. Soundproofing is really good, actually better than the previous two, and the comfort is much better than to plug it into the ears.

but!

Wax balls are really wax! ! ! Sticky! ! ! ! After plugging your ears, your fingers will be a little sticky! ! ! ! ! After using the ear hole, it feels sticky! ! ! ! !

3M Earmuffs: Wasteless Waste!

Then compare the scene noise reduction capabilities, noise index from the mobile phone detection, certainly not allowed, but relatively speaking, can be a little reference to the comparative value,

The bus (Qingdao) has a noise peak of 82dB. There are no front and rear streets around Qingdao. Only in the front and rear, buses frequently increase the horsepower uphill and downhill. Some older models may have a lot of noise.

The subway (Qingdao) has a peak noise level of 90 dB. Qingdao’s subway has just passed a line. The number of trains is still not very high.

Main Street, Expressway (Qingdao). This road is a new road. The road is wide and wide. The car runs smoothly and the noise is around 70.

The high-speed rail, for the purpose of this evaluation, I deliberately sat for a few minutes and sat back there. It was said that the high-speed rail was really good. At the time, the speed was 179, but the noise was only 60.

Each section of the noise reduction effect, if it is a percentage system, QC35 can give 90 minutes,

750NA: A good noise reduction effect can give 75 points, especially in the subway, the moment of noise reduction, if the QC35 is equal to directly enter another world, then 750NA is already half into another body The world, just behind the door has not closed the feeling, the ambient noise has been eliminated more than half, the station station sound can still be heard clearly, picking off the moment of the headphones, can feel the feeling of being suddenly shocked by high noise,

8850NC: Just like the price, it really is an entry-level noise reduction effect, with a maximum of 60 points. The best use of the effect is on high-speed rail and public transportation. The noise around it can be reduced, and the wireless design should be given when you sit outside. When people give way, they will reduce a lot of trouble. I just wore the 750NA for a while, so I simply replaced the goods.

Ohropax, soft=bright, the sound insulation (noise reduction) effect after wearing is completely better than the above active noise canceling headphones, including QC35,

I used to use the QC35 to make comparisons. In addition to not listening to music, the ability to isolate ambient sounds can be stabilised steadily over QC35. Of course, if the goods are used together with the QC35 (not at all), the effect will be better. , there really is a feeling of deafness,

Wax balls still have no love, and their sticky hands feel uncomfortable.

3M Earmuffs: Garbage!

These prices are not expensive, the most expensive 750NA is also only four or five hundred, but also worthy of use, I am ready to use, do not want to wait for qc20, and wait for the goods to wait for the QC30 upgrade,

Although the entry level is really some active noise reduction, wood ear requirements are not high enough to listen to the sound quality, plus wireless, only 299 yuan, anyway, I did not feel sorry to buy Philips 8850NC, just throw the office, not afraid to lose, see The movie opens and the phone is very good!

Ohropax: Do not buy wax pills. The rest is fine. If you don't want to use active noise canceling headphones, it's just a sound. If you don't want to use detours, buy 3M or domestic imitation goods and buy Ohropax. On the line, more than 30 boxes per day can still be used for more than half a year.

3M earmuffs: anti-human design, super chuck, noise is also much worse than earplugs, do not buy a pure waste of money.
