We always have an obsession with headphones, that is, we don't care about the price, only care about the suitability! Because, in our opinion, for the average ear, as long as it is **179 headphones, unless you repeatedly compare and listen to the same track in a specific environment, it is really difficult to find a big difference. And today, what we share with you is the headset sent by Hey's family, which claims to be a low-cost assassin, how about it? Let's take a look!
Since it was a trial product, I didn't get too many parameters about this headset. It is only known that it uses a 40mm super large dynamic sound unit, and it has also won a small gold standard. With a small gold standard, it means that the sound quality of its headphones is still relatively reliable! 
This is especially evident when we listen to Cai Qin's classic "The Ferry". The powerful impact of the drums in the intro and the deep dive combine to create an exciting atmosphere. However, this strong bass drum sound does not overshadow the sound of other percussion instruments, but rather coexists harmoniously with it. This balance is also reflected in the elegant vocals and soulful vocal expressions. It can be said that the Haylou S30 headphones bring us richer sound details with their large diaphragm design. This delicate listening experience stands out compared to other headphones. 
We also tried to listen to "Hunting Polka", which has a richer sound layer and requires a higher resolution of the sound unit. Even if the headphones are not burned-in, the Haylou S30 still shows impressive performance. On the one hand, the crisp and loud sound of the shotgun is precisely conveyed, giving people a sense of immersion. On the other hand, it also brings an immersive playing experience. Whether it is a string group, a woodwind group, a brass group or a percussion group, it can be excellently restored, and the details are clear and recognizable, making people feel as if they are in the scene of the ** meeting. 
It seems that the headphones equipped with a 40mm dynamic unit do have advantages that small dynamic headphones cannot achieve in addition to the sound performance. From another point of view, the current domestic headphones on the 40mm track have also made the gap between us and foreign brands gradually smaller to today's minimal, which is quite gratifying. 
The current headphones, if you don't say that you have noise cancellation, are almost embarrassed to say hello to others. As a headset that costs less than $200, the Haylou S30 has just as good noise cancellation. 
In the ** air-conditioned room, it can easily filter out the sound of the air conditioner's fan, NAS fried bean reading plate, etc. Even the sound of firecrackers exploding in the middle of the night has attenuated. 
However, for vocal filtering, it is basically similar to other headphones with noise cancellation, the sound will be reduced but still clear. In addition, it also comes with an ambient mode and an outdoor mode, which is quite intimate. 
As a headset, the Haylou S30 still feels good to wear. It has a lightweight design and weighs around 297g overall. 
Its headband and ear cups are designed with protein leather + sponge, so the weight is evenly distributed when worn, and there is no feeling of falling head. 
Haylou S30 uses an in-line microphone, which can provide clear communication for friends in a more noisy "black" environment than a hidden one.
Plugging it in when we use it gives us better directional radio. When not in use, it is more neat to dismantle and very convenient. Although this is a headphone priced at only RMB179 yuan, with the blessing of the big dynamic coil, it has not only obtained the certification of the small gold standard, but also provided us with good sound quality. It supports wired and wireless dual connections, is equipped with an in-line microphone, comes with a variety of usage modes such as noise cancellation, outdoor, and ambient, and also has its own exclusive app. It can be said that the functions you want to get, Haylou S30 has them! If you are a gamer who is looking for sound quality and cares about value for money, then the Haylou S30 is indeed a good choice.
