1. AKG K3003

It feels a bit overwhelming. Not only the price, but the sound is also very sharp. The low frequency is actually enough, but I personally feel that some music cannot be heard from the low frequency. It feels refreshing, which is a pity, because a lot of modern music, especially electronic music and dance music, particularly emphasizes the bass dive. In the field of low-frequency dive and low-frequency dynamic analysis, three The best among the headphones is the IE800. I haven’t heard anything better than the IE800 so far. The K3003’s mid-to-high frequencies benefit from the moving iron unit. The sound density is extremely high and the resolution is high, but because AKG has always The tuning style of the voice is thin, so the high-density and high-resolution sounds in the mid-to-high frequencies will make people feel a little irritated and unbearable. In addition, I feel that the K3003 is the weakest among the three. Just like opera singers, bel canto singers, and ethnic singers, they all know how to sing, but when they perform pop performances, you will feel that they are indifferent and lack that kind of "foreign flavor" , to put it bluntly, the sound is not popular enough.

2. I personally feel that Sennheiser's IE800 is more natural than K3003. This naturalness is mainly reflected in the mid-to-high frequencies.

The moving coil gives people a warm and loose feeling, especially after listening to the K3003 and SE846 and then listening to the IE800, I feel that the sound flows with ease. The most powerful thing about the IE800 is not the low frequency, but that it operates in such a narrow range. It has an extremely wide frequency response per unit area. Let’s not talk about whether the frequency response is a gimmick across brands (such as some Japanese brands), but as far as Sennheiser itself is concerned, products with wide frequency response are rich in Hi-End attributes.< /p>

Sexy, the IE800’s low-frequency dive is abnormal, but it won’t make anyone feel fake. The mid- and high-frequency is very natural, especially when performing musical instruments. People say that the IE800 I don't agree with this point. Asians and Europeans have different vocal frequencies. I think the IE800 sounds gorgeous after interpreting typical Asian female voices such as Faye Wong. But When it comes to expressing the vocals of European and American pop music,

it is a little less emotional or more straightforward, and the vocals have fewer overtones. Personally, I feel that the IE800 is the most balanced among the three, with powerful instruments that take into account the popularity. Compared with the previous IE8 and IE80, the vocal quality has improved a lot

If you like Sennheiser tuning, you can safely upgrade. The only dissatisfaction I have with the IE800 at present is that it would be better if the horizontal sound field was wider: )

3. From the birth of W4r to the launch of UE900

Shuer seems to be the most calm one. When I always mistakenly thought that Shuer wanted to conquer the world with SE535, Shuer finally released SE846 after many years of development! As an old moving iron manufacturer, I think Shuer's insistence on technology as the core rather than launching a multi-unit to fool consumers in a hurry to occupy the market is really worth learning from many big manufacturers, especially Sony's moving irons. Headphones should really be reconsidered.

In short, Shuer gives people the feeling of having accumulated a lot of experience this time. Whether it is price or technology, it has attracted the attention of enthusiasts. But in front of the sound, those gimmicks are actually useless.

SE846

The first feeling of listening is that it is stuffy. Damn it’s all kinds of stuffy. As soon as I put it on my ears, I want to complain, but I still think silently in my heart that these are 7k soft girl-priced headphones. , listen again, listen again, the tuning of SE846 is different from that of SE535

It’s not so loud, the sound is no longer so linear, the sound has been polished and has a lot less edges, I don’t know if it’s because of the low frequency It’s caused by this, but it feels fleshy. Some audiophiles may prefer angular sounds.

It’s not easy to adapt to this kind of rounded sound trend that is more analog. This time, the sound of SE846 is due to the low frequency. The return of the sound field has become much more three-dimensional than that of the SE535. The dynamics are actually quite sufficient, but I always feel that the low-frequency structure has a greater impact on the mid- and high-frequency levels, so the whole sound sounds a bit stretched. I Later, I took a closer look at the black sponge of SE846. It is different from the previous ones. There is actually a layer of plastic filter inside the black sponge, and the grille is thicker. I don’t know if it is. Because of this reason, because the sponge cover of the trial earphones was too tight, I didn’t dare to pull it out, so I didn’t try it. Students with SE846 can try changing to the black sponge of SE535

or try using silicone or catheter. Have you tried to see if there is any improvement? In short, I am not satisfied with the SE846 in the default configuration. The only reason is that the taste is too strong. However, these headphones are very playable. I will change the high-frequency tube and use silicone.

Maybe it will be another piece of blue sky~~

If you have a good front end and want to keep it fresh for a long time, choose K3003.

If there is a good sound source that is more sensitive to musical instruments than human voices, choose IE800.

The popular one is SE846, but the enthusiasm is a bit too much and needs to be controlled through accessories.

In addition, there is still a big gap between W4r and UE900 compared to these three. After listening to SE846 and fitear 334, listening to them again will feel very childish.
