AKG k420 has a rattling sound when it turns! How do you do that?

I also have K420, and it's only on this side, and I found an article to fix this little problem, which needs to be disassembled, and there is a plastic thing rubbing inside. Actually, I don't care much, as long as I don't move the hinge when I listen, it won't ring...Be calm....Or go to the after-sales service for another one.

If you are willing to take it apart yourself, you can try to check for plastic burrs. This is the solution to the root cause. I'm Diyer. When I encounter this kind of thing, I usually do it myself.

Generally, portable headsets have this problem.

Just wear it for a long time, and maybe it will get better slowly.

LZ doesn't have to worry too much.

If it's a quality problem, then look for after-sales.

In fact, there is no needK450,If the cost performance is higher, it is420and518le,If it's a mobile phone,It means that your front-end is not too good,If you want to listen to it more comfortable and transparent,And you can hear other sounds,420OK; The sound insulation of the 518 is much better than that of the 420, but the 420 feels more comfortable to wear (personal feelings, don't shoot differently). Headphones at this level,Can meet the needs of most people to listen to songs,My front-end 864,Now it is equipped with 420,The headset on the computer in the office is 518.The above is just a personal feeling, and the landlord can try it according to his own needs.

I highly recommend 420:

First, the cost performance is very high, within 500 yuan, the evaluation has been very high, which is recognized by the public.

Second, it is portable and safe, there is no problem when going out on the street, it is transparent and comfortable, and you can hear the sound of vehicles on the street (it does not affect listening to songs). Especially when you go on an outing, you can enjoy life in the mountains or by the river (I went to the Yellow River the day before yesterday).

Third, it's not expensive, less than 300**, even if it doesn't suit your style, you can also use it as a high-grade headset backup when upgrading other devices, hehe......(This article is exempt).

It's OK to choose whether to choose or not as the answer, and I hope the landlord will find his own good headphone ......

It is recommended to get the front end right first, after all, the mobile phone is not the material to listen to.

Directly into the K450+ mobile phone, I personally think it is the worst choice,The sound of the mobile phone pushing K450 will feel very general,It will make you want to change the front end immediately。 With such a combination, I personally feel that one ear feels really not as good as C3+K420.

If you usually listen to some pop songs, it is better for you to consider using the 700 yuan to buy a Meixing S764, listen to the original headphones for the time being, and then consider the headphones when you have money.

420 plus C3, I bought 450 but I can't fully play the strength of 450 if I can't do it in the previous paragraph, as for the benefits of 420, it's clearer upstairs.

It is recommended to use K518LE, the sound quality is better, the sound quality of K420 is slightly rough, and the bass of K450 is slightly muffled.

If broken sound is a common phenomenon,It's been crippled by you.,How much volume do you use on the computer?,K420 It's too loud at the lowest volume on my computer.。。。

K420 didn't need to be deliberately cooked.,Just listen to the natural cook.,Deliberate burn-in has long been outdated.。。。

7-day return, is without affecting the secondary sales, K420 one-time packaging, you have disassembled, it is impossible to return it in 7 days. Discuss with the seller whether the warranty can be guaranteed or returned due to quality problems in the three guarantees. But I don't think anyone will agree to you.

If the ** store has a promise of seven days to return, then congratulations on the eighty percent you bought that is a fake. The one-time packaging of licensed earphones is absolutely impossible to return after unpacking.

There is no need for K420 headphones of this level to be cooked, and the thrust of the computer is generally larger, and if you are not careful, the sound may be too loud and the pot will be damaged...

Wear it and listen to it, if the broken sound continues to exist, then go and return it.

Again, the merchant is willing to return the headphones if you have broken them, which can only mean that there is a problem with what he sells! ~~

Is the sound break serious? Are you sure it's the headphones themselves?

**Returns are often more troublesome, and it is good to return them without a reason, but the postage may be borne by yourself.

Try it for two more days, change to another machine or listen to it, if it is still broken, it is better to return the postage of the flower shop.

It's true, my classmates and I have bought it, and it's the same as the Arden licensed product that my friend bought, and the sound is the same.

The buddy of 1l is pure nonsense.

K420 is flooded with fakes.

However, Nanjing Huisheng is a time-honored brand.

It is impossible to sell fakes.

It is said to be an international version, and it is a genuine international version.

Buy with confidence.

LZ Loud Stuff is believable.

There are a lot of fakes in 1L K420.

The term "international version" is very common in the headphone market, and merchants often say that the "international version" is a parallel import and is flawless in quality. We are here to remind you that only AKG products with the anti-counterfeiting logo of Arden Musical Instruments are licensed, and other so-called AKG "international versions" are non-****, and quality and after-sales cannot be guaranteed.

This question is basically not asked.

Just by virtue of the name of Hui Sheng.

First of all, the sensitivity of K420 is 125DB, the phone can definitely push, and it is pushed very well, I myself use an Android phone with K420, and even I use my phone to push the Edifier H850 such a lower sensitivity (96DB) headphones are not bad.

As for you to change a 300 or so ***, I personally don't think it's necessary, if the effect of the mobile phone comes with the **device can't meet you, you can try**playerpro or poweramp like this**device,This kind of **device supports equalizer adjustment,As well as simple reverb adjustment function,You can try these mobile phone applications。

Hope these are helpful to you.

K420 does not have the problem of driving difficulty, and can have good performance when used in mobile phones or ***. If you are satisfied with listening to the song on your mobile phone, you can not buy it separately***, and you will have the opportunity to enter a better front-end in the future.

Hello, the K420 belongs to the entry-level headphones because of its low impedance and high-sensitivity design, suitable for direct pushing.

Even if it is a direct push, there is no problem at all.

If you need Hifi-grade headphones with some potential at this price point, I recommend Beyerdynamic.

DT235 will be happy to answer your questions.

K420 is particularly easy to push, and there will be no better than the Nexus S below 500*** It is recommended to install a rockbox or poweramp on the phone, and the sound improvement is obvious

The K420 only leaks a little bit more than the average earbuds, which is hardly the difference. The sound is not very loud, and others still can't hear it. **250 or so, it is recommended to go directly to **** to buy, **265 can start, ** is generally no problem.

As long as ** is not less than 220, there is a query code for you to check, it is a real license. It is possible that the Hong Kong bank and the international version are fake.

They won't be disturbed when they're sleeping.

You won't turn up too much in a quiet environment.

**As long as it is Arden's licensed, it is reliable.

Listen to it at night when it's quiet, and it is estimated that people who are sensitive to your voice will have an impact, but I used to listen to it at night, and my roommate also said that the sound is loud, unless you use it in your ears, otherwise other people generally hear it when you sleep at night, or you turn down the volume very low. It seems that there are more than 250, excellent 299, and there is still a shadow on **, especially the headphones.
