As an amateur network code word dog, I haven't written many pieces of flapping streets, but the code word dog should not have so many problems. Especially when it comes to coding, I'm very sensitive to all kinds of life noises. Noise has become a powerful excuse for me not being able to become a god.
I've never been on Aunt Zhang. In fact, until last year, I learned that there are actually anti-noise headphones in the world. Before that, I used 3M noise earplugs and earmuffs to reduce noise.
3M earplugs cost around 10 yuan per year, with 10 pairs, which is cheap enough. However, they don't offer much comfort. The soundproof earmuffs are large and thick, designed in a way that makes you look like a fool when wearing them. They're not very useful outside the home and are only occasionally used at home.
Later, I found out about Ohropax, the so-called leader in the earplug industry. I bought two boxes of the soft series. Compared to them, no matter the comfort or sound insulation, 3M's earplugs were clearly inferior.
I then tried several domestic products, such as certain zero, one suitable, one excellent, etc., but none could match Ohropax. From then on, I stuck with them and still use them today.
The brand is called Ohrfrieden on some domestic platforms, with the Chinese name "An Eryou." There's some debate online about the relationship between Ohrfrieden and Ohropax. Some say that since Ohropax is registered in China, it can only be renamed as Ohrfrieden. I don’t know the exact details, but I bought two sets from a friend who brought them back from the Netherlands. When comparing them, they seem almost identical.
Now, I only have one pair left in the soft series.
Later, I also purchased the colorful and wax pill series from the same brand, which offer better noise reduction effects. I'll explain their performance below.
In addition to using them during the day while working or coding, my home is located in a street building with constant noise during the day. So I developed the habit of inserting earplugs into my ears when it's not bright. This helps me feel more relaxed even before eight o'clock. Sometimes, after six o'clock, there's a lot of noise, and one day when I couldn't sleep, I wore the earplugs and just listened to my breathing, which helped me fall asleep quickly. It has truly become an essential item in my life.
Occasionally, I picked up a headset in an Apple store and wanted to see how expensive it was (priced at 2800). After the clerk explained, I realized it was an active noise-canceling headphone, specifically the QC25. I tried it, and the clerk turned on the noise reduction feature. At that moment, my eyes lit up—like entering another world, completely isolated from the noisy mall around me.
From that point on, I learned about the QC35 and soon bought a pair.
The noise reduction effect was as good as in the store. It’s quite satisfactory, and the wireless feature is very convenient. It doesn’t cause the same hassle as earplugs. The sound quality is amazing for someone like me, who has a "wooden ear." Overall, it's almost a perfect noise-reduction product.
In addition to the design of the QC35, the thick sponge on the top of the headband is also notable.
The red coil in the picture:
There will certainly be many people who say that if a product has such thoughtful and humanistic design and improved comfort, how could anyone still complain?
I really didn’t want to shirk, because the design may be great for 99.99% of people, but I’m part of that 0.01%. My head shape is slightly pointed, not round, and this makes the design of the QC35 uncomfortable for me. Even after wearing them for less than half an hour, the pressure on the top of my head becomes increasingly uncomfortable.
I’ve tried various ways to improve comfort, including awkward adjustments, but it’s hard to wear them without them falling off. Also, if the earmuffs don’t fit snugly against the ears, the entire noise reduction function feels compromised.
After wearing them for half a year, I finally reluctantly gave them to a local friend.
Now, I rely on noise-canceling headphones. Without music features, regular earplugs no longer satisfy me. I definitely need to buy a noise-canceling headphone, and my target is still the leader in the noise-reduction industry.
I’ve looked at the QC25, QC20, and QC30. The QC25 and 35 designs are nice, but the price is too high (even 900 during Double 11). The QC30 shocked me with its plastic material and gaps. It seems easy to open, and even if I got a new one, it would cost around 1.7 million, which made me hesitate.
QC20 is an older model, but it has passed market tests. Its sound quality is good, but I don’t care much about that. The price is usually over 2000, and even if it drops to 1200, I always feel like I'm losing money. I waited for the Double 11 for a while, hoping for a good deal.
During that time, the Sony MDR-1000X was priced at 1399. I was so excited that I fell asleep waiting to buy it that night!
Two more blinks naturally missed the chance.
Meanwhile, I came across the Philips SHB8850NC, which is Bluetooth wireless and offers active noise cancellation for just 299.
At that time, I was in a noise-reduction vacuum. I thought it wasn’t expensive, so I decided to buy it for the office.
When I received it, I was surprised. The sound quality was decent, and the noise reduction was effective. It’s pretty cheap, so I just put it in the office for calls and movies. I’ll explain the noise reduction in more detail below.
Later, I found out that the QC20 didn’t have any promotions, which was frustrating.
JD.com said it was 1499, but I didn’t see it. I only saw it was out of stock or priced at 2000.
On Taobao, it required a deposit and was inflated. My sister tried it but didn’t even look at it. All my plans were shattered.
At that time, I accidentally saw the Sony 750NA, which was discounted to over 400. I checked it out and found it usually sold for 1199, sometimes as low as 800–900. Friends on Aunt Zhang shared positive reviews, so I decided to buy it, thinking it was worth trying.
As a result, I ended up with six noise-reduction devices: the Sony 750NA, Philips 8850NC, 3M noise earmuffs, and three pairs of Ohropax earplugs.
Objectively speaking, none of them are perfect. Each has its own shortcomings and advantages (except the 3M earmuffs), and they each have their own comparative value.
Before that, I had only made two prototypes. I don’t know how long I’ve been diving into this. Originally, this stuff was really addictive, so even though these are all bargains, I’m still trying to compare them and share my thoughts with others. If it helps someone, that would be the best.
Next, I will compare their noise-reduction capabilities in a few common scenarios, such as buses, subways, streets, and high-speed trains. Since I’ve used the QC35 for six months, I’ll also include some subjective experiences with it.
First, a brief commentary and personal feelings on wearing them.
750NA: It reduces noise well, but not extremely. Especially when it's quiet, the difference is obvious once you play music. The earbuds aren’t designed very well. I often worry they might fall, although most of the time, they stay in. It’s not suitable for activities. Comfort-wise, since I’ve been plugging in earplugs all year, this in-ear style isn’t a problem for me. I can wear them for hours, and the sound quality is at least as good as Apple’s original.
8850NC: Clear noise reduction, and the same music can completely cover it. It uses a non-early ear clip design, and doesn’t squeeze the ears too hard. There’s no sponge on the top of the headband, which I really like. Unlike the QC35, it doesn’t cause discomfort for me, so I can wear it for a long time. The sound quality is satisfactory, and I prefer it for listening to music compared to the 750NA.
Ohropax’s soft and colorful series, refer to the official website map.
Noise reduction on the bright series is better, and the comfort is also better. Personally, I feel the difference is subtle, and it’s difficult to tell the difference. It’s essentially the same to buy, but the colorful ones allow for color differentiation, which is an advantage.
As for the wax pills, they use a thin layer of cotton wrapped around a piece of sound-insulating wax. Before use, you tear off the cotton and insert the wax pill into the ear. Note that it shouldn’t go inside the ear canal. The noise reduction is really good, even better than the previous two, and the comfort is much better than inserting earplugs.
But! Wax balls are really wax! Sticky! After plugging your ears, your fingers get a little sticky. After using the ear hole, it feels sticky!
3M Earmuffs: A complete waste of money.
Then, comparing the scene noise-reduction capabilities. I can’t use phone detection for accurate noise levels, but relatively speaking, it can serve as a reference for comparison.
Bus (Qingdao): The noise peak is 82dB. There are no front or rear streets around Qingdao. Only in the front and rear, buses frequently increase horsepower uphill and downhill. Some older models may be very noisy.
Subway (Qingdao): The peak noise level is 90dB. Qingdao’s subway has just passed a line, and the number of trains is still not very high.
Main Street, Expressway (Qingdao): This road is new, wide, and cars run smoothly. The noise is around 70dB.
High-speed rail: For 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 60dB.
Each section of the noise reduction effect, if it's a percentage system, the QC35 can give 90 points.
750NA: A good noise reduction effect can give 75 points. Especially in the subway, the moment of noise reduction, if the QC35 is like entering another world, then the 750NA is already halfway into another world, just behind the door hasn't closed yet. The ambient noise has been reduced by more than half, and the station sounds can still be heard clearly. When taking off the headphones, you can feel the shock of sudden loud noise.
8850NC: Just like the price, it's an entry-level noise reduction effect, with a maximum of 60 points. The best use is on high-speed rail and public transportation. It reduces the surrounding noise, and the wireless design is convenient when sitting outside. People giving way reduces 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 the QC35. I used to compare with the QC35. Except for not listening to music, the ability to isolate ambient sounds is stable and even better than the QC35. Of course, if used together with the QC35 (which I don’t do), the effect would be even better. It really gives a feeling of deafness.
Wax pills still have no love, and their sticky hands feel uncomfortable.
3M Earmuffs: Garbage!
To sum up: These prices are not expensive, the most expensive 750NA is also only four or five hundred, but they’re still worth using. I’m ready to use them, don’t want to wait for QC20, and don’t want to wait for QC30 to upgrade.
Although the entry level is some active noise cancellation, the sound quality requirements for a "wooden ear" are not high. Plus wireless, only 299 yuan, anyway, I didn’t feel sorry for buying the Philips 8850NC. Just throw it in the office, don’t fear losing it, watching movies and answering calls is very good!
Ohropax: Don’t buy wax pills. The rest is fine. If you don’t want to use active noise-canceling headphones, it’s just a simple earplug. If you don’t want to take detours, buy 3M or domestic imitation products 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 bulky, noise is also much worse than earplugs. Don’t buy, it’s a pure waste of money.
