For headphone enthusiasts, Hifiman is undoubtedly a well-known brand. It has launched quite a few products, from players to earphones to corresponding accessories, which can also form a set of its own Hi Fi system, and its sound performance is also highly praised. Not to mention the controversy over its famous listening concept, Hifiman has become a successful brand in any case.

Those who pay attention to earphones must have heard and know the concept of flat earphones, and often know the high price and high quality it brings, which is often called the choice of fever. Hifiman also has its own tablet headset series. The high-end HE6 and the sub flagship HE560 are impressive, but their prices are also impressive. This time, the price of the HE-400i, which is more affordable, is also at the classic price of 2499, which must be full of strength.

The HE-400i should be the main price performance ratio in Hifiman's flat earphone series, but its packaging is still Hifiman's consistent high-end atmosphere. The appearance describes the corresponding parameters and rendering.

There is also a leather packaging box inside, and the leather handle is quite eye-catching.

This is not a retail version, so there may be some differences in the parts. Just take a look.

What should I say? Because of the structure of the flat earphone, its appearance design may give you a retro feeling. The HE-400i is basically the same as the products before Hifiman in appearance design. It uses an integrated head beam design, which can adjust the wearing length. In terms of cavity, the HE-400i does not use wood grain decoration, but the previous metal paint, which is relatively low-key. On the external side of the cavity is a metal mesh cover. With so many small holes, will there be fear for people with dense phobia? (laughing)

In terms of pins, the HE-400i is still the usual design, but according to the consumer's reaction, it has been slightly adjusted in position compared with the HE-560, so as to avoid the pricking feeling of the HE-560 when wearing. In addition, the last i of HE-400i also means that it is specially designed for mobile devices, that is, iPhones and other products. Therefore, the original headphone cable is also 3.5mm bent.

The HE-400i can also rotate the headset 360 ° and turn it 180 °, no matter what position you are in, it should be enough.

This is about the actual equipment and length adjustment.

Then there is the actual wear. For girls, the flat earphone looks a little bigger. Although the HE-400i looks large, it is relatively comfortable because of its light weight and less pressure. For more specific technical introduction and detailed listening sense, let's wait for the slow boiling and then detail the table.
