Main features：

1. Flat diaphragm earphone

Flat earphones and electrostatic earphones are similar in sound characteristics. Both have the characteristics of large amount of information, strong extensibility, and low distortion. They perform well in transient and dynamic aspects.

Since the conductor layer (voice coil) on the diaphragm of the flat earphone is evenly distributed on the surface of the diaphragm, the electromagnetic force that drives the diaphragm to vibrate and produce sound acts on the surface of the diaphragm than the voice coil acts on the cone diaphragm of the moving coil earphone The surface is much more uniform, so the phase distortion is much lower, the spatial information loss of sound reproduction is lower than that of dynamic headphones, the sound field is much larger, and the positioning is much better.

Because of this, the frequency response of HE400se is wide, from 20Hz to 20KHz, the three-dimensional sound field is beyond the head, and the positioning and image of the instrument are as precise as the tip of a needle.

2. Easy to drive

Thanks to the HIFIMAN flat panel drive unit technology, the high sensitivity of HE400se, coupled with the impedance of only 25 ohms, not only surpasses the older generation flat panel earphones, it is also easier to drive even when compared with the main mobile ring earphones, 70% in smartphones You can listen to music at a higher volume when the volume is higher.

3. Comfortable fit, enjoy all day

The newly designed pull-out head beam further reduces head pressure and maintains ventilation space, so that the head will not feel heavy pressure and stuffiness.

4. Reduce weight while being more durable

The surface shell of the new headphone unit uses a new process, and the plating and mechanical life are increased by 30% on the original basis, and the weather resistance of wet areas is increased.

5. Simple and reliable wire interface design

The headphone wiring of the HE400se can be easily removed. The headphone wiring is connected to each channel with a separate ground wire to reduce the crosstalk between the left and right channels to a very low level. The signal line plug wears a standard 3.5mm small plug, which can be passed through the 6.35mm socket on the street. You can also purchase a headphone cable with a balanced plug to try the advantages of a fully balanced structure drive.
