Nowadays, most high-end portable earphones adopt in ear design, and even more and more customized earphones are gradually coming into our view. The classic earplugs that used to be popular in the walkman industry all adopt the flat head design, such as the MX500 and E888 that we are familiar with. However, in the past one or two years, the flat head plugs seem to be too many products that can be sold. Recently, HIFIMAN, a famous domestic manufacturer, launched the flat head plug product ES100, which has attracted a lot of attention. We also got the retail version of ES100:

The outer package of ES100 is wrapped with a transparent plastic box, and it is marked on the front that ES100 adopts a 15mm dynamic coil unit.

More detailed parameters are marked on the back. The frequency response range of ES100 is 15Hz~20KHz, the impedance is 150 Ω, and the sensitivity is 113dB/mW. The impedance and sensitivity are relatively high. Although the impedance is relatively high in the earplug, the sensitivity is also very high, so it should be easy to push

The inner layer of the package adopts paper packaging, which can be pulled out at the bottom corner immediately.

ES100 is wrapped with transparent film inside the package.

Turn over the back to see the ES100 wire.

The earplug cavity is dark blue with a bright surface. It can be seen that there is a small bulge at the rubber ring of the earplug. The purpose of this is to make people wear it better. As far as the small braided ear is concerned, the ES100 is relatively comfortable to wear, which is slightly better than the round flat head plug.

There are two air holes on the earplug.

3.5mm contact pin adopts L-shaped head design.

There are brand and model at the distributor.

The accessories of the ES100 are very simple, including a simple description, a headset protective sleeve and a wire winder.

Another detail is that two silicone sleeves are attached to the engineering version ES100, while the official version even uses adhesive tape to cover the words of the silicone sleeves in the manual, and no silicone sleeves are attached to the accessories.

Since we just got ES100, the earplug itself must not be in the state, so here is a brief talk about the sense of hearing. The overall sound style of ES100 is relatively soft and balanced, and its voice is relatively neutral. There is no obvious preference for the frequency band of the voice. At first, it gives people the impression that it is a "boiled water" style. This moderate sound style is believed to be popular with many users. In terms of tri frequency distribution, the high frequency of the ES100 is clear, but not too harsh. The mid-range is medium in thickness, and the vocal distance is just right. It is suitable for listening to pop music. Low frequency is not the advantage of ES100. The sense of low frequency is not big, but the texture is good. In addition, it may be that the plug has just been unpacked, so the voice seems tight and too bright, and the dental sound of the voice is also obvious.

In terms of wearing, for Xiaobian, perhaps due to the small protrusions on the silicone sleeve, his ears are easy to ache after wearing for a period of time. In addition, this kind of flat plug with short handle is particular about the way to wear it. If it is not worn well, it is easy to have a shriveled sound, and there is no low-frequency phenomenon. In addition, it is not convenient to remove the short handle flat plug. The ES100 is a kind of earplug with high sensitivity and high resistance. It is not a big problem for ordinary walkman in terms of driving. Some mobile phones with high thrust also show a clear sense of order. As far as the price of 399 is concerned, we still give our affirmation to the sound performance of ES100. However, compared with some high-end earplugs, the quality of ES100 is not cheap. The most attractive thing is its balanced and loose sound style, We are also looking forward to its performance after boiling.
