often hear people say "HIFI poor for three generations, and SLR ruins their lives." Although it is a bit exaggerated, it means that if you pursue the ultimate audio-visual experience, you will have to pay a high price. Many players spend a lot of money to improve the standard little bit, and the high price also discourages many ordinary people. It’s like you can’t hear a good voice if you don’t buy expensive ones. In fact, many mobile phones and computers now have no worse ability to process encoding than the professional playback " brick machine ", which is lacking only the lack of thrust on the final audio. Just add a pre-level headphone amplifier and headphones to match professional playback equipment. HIFIMAN EF400 decoding headphones are all-in-one models that allow you to use your phone to match headphones so that you can experience the ultimate sound of music at a very small price.
[Product Packaging and Appearance]
HIFIMAN (Haifeiman) The packaging of the EF400 decoding headamper adopts the concept of minimalist to exquisiteness. The entire outer packaging does not use too many elements to modify, fully reflecting the concept of environmental protection. The paper shell of the pulp is made of colored product photos on the front, with the product brand name and product model marked on the upper and lower, and the instructions for graphics and text are printed on the back. When you open the outer packaging, you can intuitively see the main product of the ear amp wrapped in sponge, and the packaging manufacturer has a power cord standard. I chose an ANANDA diaphragm headset music headphone of the same brand with the earmatch, and adopted the same style of outer packaging.
HIFIMAN EF400 decoding head amplifier all-in-one machine adopts an all-metal shell, with a basically similar appearance to the music amplifier. The flat rectangular design is only reduced in size, but the weight reaches 3 kg. It is not only stable when placed on the desktop, but also effectively avoids the noise caused by resonance .
HIFIMAN EF400 decoding headamper all-in-one machine uses a silver aluminum brushed panel on the front, reflecting a calm and atmospheric style. Two knobs are symmetrically placed on both sides, and the surface is covered with CD patterns to echo the panel. The gain knob on the left is a total of four modes: High/Low Gain OS and High/Low gain NOS. The volume knob on the right is. Four output interfaces are placed in the middle position: 3.5mm, 4.4mm, 6.35mm and four-core XLR balanced.
HIFIMAN (Haifeiman) The back of the EF400 all-in-one machine is the other two output interfaces of the XLM balance and RCA, which basically covers most of the output devices. The output end only retains two mainstream digital interfaces, TYPE-C interface and USB-B, and is also well connected with current players and mobile phones.
HIFIMAN (HEFMAN) Four-point silicone anti-slip foot pads are designed at the bottom of the EF400 earmachine, which further increases stability. Two voltage switching rods are also placed, which can adapt to the standards of different countries.
[Function Trial]
HIFIMAN EF400 decoding headphone all-in-one machine uses the self-developed HYMALAYA (Himalaya) DAC chip to decode digital audio into analog signals. Because the headphones have built-in high-current amplification circuit , it ensures strong thrust, so it can reflect the delicate sound quality that ordinary players cannot present. I just used the most common mobile phone to connect through the dual TYPE-C interface cable, which should be the most common playback mode at present.
This time I used HIFIMAN EF400 decoding headphones to listen with the same brand ANANDA diaphragm headphones. The combination of the two can fully demonstrate the matching degree of the same brand, which can be said to be a perfect match.
For the audition of the three-band sound, it needs to be interpreted through different songs. I play the songs of different singers such as Dai Quan , Eason Chan , Jacky Cheung , and Jacky Cheung . In the high-frequency part, Dai Quan used a quick song " Wukong ". HIFIMAN EF400 interprets the unrestrained and enthusiastic singing style to the fullest, with transparent high notes and no drags on them, especially the control of high-frequency distortion is excellent.
In terms of mid-frequency, I chose an old song by the singer Jacky Cheung, " Kissing goodbye ", which well shows the layering of the vocals. The singer's harmonious part expresses the low and euphemistic style just right. The soundtrack and vocals do not mix and influence each other, but rely on each other and are clear and independent.
low frequency part I chose Eason Chan's song "The Lonely Brave". Although it is not a heavy metal track, the HIFIMAN EF400 decoding headphone all-in-one still performs the diving depth of the bass part very well, and you can clearly feel the shock of the low frequency part. When paired with the large-unit headset , there is no need to worry about the soft feeling brought by insufficient thrust, which is enough to show HIFIMAN's excellent sound tuning ability.
[Trial Summary]
HIFIMAN (Haifeiman) EF400 decoding headphone all-in-one machine has a classic appearance, a compact design, built-in self-developed professional HIFI chip, strong decoding ability, large thrust, and good compatibility. Even mobile phones can immediately become a professional music player, and the sound quality is no less than that of the "brick machine" and the flat diaphragm headphones of the same brand are perfectly combined.
(my trial data is limited to the devices I use. Due to individual differences in the equipment, there will be different data from other equipment)
