More warm and thick listening to the Cardas EM 5813 in-ear headphones

Cardas launched the headset! This EM 5813 in-ear headphones is probably the most in-ear earphone I have ever taken, and the thick body shows that Cardas is still the background of the wire, showing their self-adherence in designing headphones. For the launch of the EM 5813, Cardinal Vice President Andy Regan personally came to Taiwan to hold a press conference. How did the name of EM 5813 come from? The answer is Ear Mirror, which means that the earphone is the mirror of the ear, reflecting the most realistic sound, but how does 5813 explain? Oops, everyone forgot to ask at the press conference. I tried Google and opened the house number, phone number, electronic chip number, etc., leaving only the asteroid 5813 closer to the possibility of naming. Sorry, that's what I guessed. I can't do it. When I see Andy next time, I will remember to ask for help.
The EM 5813 has two features that make the first headset of the Cardas unique. The first is the brass earphone casing, the appearance of Huang Chengcheng and the relatively large size, very eye-catching. The second feature is the proportion of super-thick wire. In fact, the EM 5813's cable is not only thick, but also very heavy. The headphone body is even heavier than the iPod Nano. You know that the EM 5813 has more weight.

The earphone casing of the EM 5813 is made of brass, and the yellow appearance and relatively large size are very eye-catching and very different.
As a portable in-ear headphones, the EM 5813 seems to be somewhat against the principle of light and good, but this headset has spent four years to design and complete mass production. Why does Cardas run to make headphones? Because Cardas' wire is very famous, many manufacturers have commissioned Cardas to design the "advanced version" of the earphone-specific wire. In order to design the special wire, George Cardas tried many of the top headphones on the market, but no one satisfied him, so he decided Do it yourself. Well, this story sounds familiar. Many audio brands are like this. The designers who are "not satisfied", in pursuit of perfection, do it themselves.
Cardas has a near-fanatic belief in the "golden ratio", their wires are the same, EM 5813 is also the case, even the box is strictly in line with the golden ratio. Where else is there to comply with the golden ratio? The arc of the earphone casing, the size of the diaphragm... Well, we can say that Cardas designed the wire and the earphones, and they always hold the "golden ratio" metric meter. Every inch must have "words", but that is The wisdom of the West passed down from the Greek-Roman era probably has nothing to do with the old-fashioned treasures.

In order to design the "advanced version" of the earphone-specific wire, Cardas tried many of the top headphones on the market, but no one satisfied him, so he decided to design himself, so EM 5813 was born...
The large size of the EM 5813 in-ear headphones is actually a reasonable design. The diaphragm used in the EM 5813 is larger than the average in-ear earphone. It is said that the size of the diaphragm is about the same as that of the average eardrum. Therefore, the size of the earphone casing with a large diaphragm must be increased. If we look at the 3D exploded view provided by Cardas, we can imagine that the EM 5813 is actually the design of the "mini speaker", the diaphragm, the voice coil, the box, etc., all miniaturized. What are the benefits of a large diaphragm? First, the low frequency performance will be better. This is the same as the speaker. The larger the bass unit size, the better the low frequency regenerative power. Second, the output sound pressure can be improved because the diaphragm area is large, the air area that can be pushed is larger, and the regenerative sound pressure is easier.
But is there a disadvantage to the large size diaphragm? Yes, efficiency tends to be low. However, in the world of headphones, efficiency is not a critical issue, because the amount of air that is not required to be pushed in the earphone is much lower than that of a normal speaker, and is limited only between the earphone frame and the ear. The in-ear earphone is stuffed into the ear. The amount of air that needs to be driven is more limited. So the actual test EM 5813, with the iPhone can also introduce enough sound pressure. Sorry, it is not just enough sound pressure, but it may damage the loud volume of the hearing. Please pay attention to the volume adjustment of the portable listening device when using it. Don't make it too loud.

Please note that the front end of the 3.5mm plug plastic handle in the picture is designed to be thin, is it good to look at it? Only half right. Most people will install a mobile phone case for the mobile phone, but often the plug can not be fully inserted, so the front end of the EM 5813 plug plastic handle is made thinner and easy to pass through the phone case. As for the wire of EM 5813, that is the selling point of Cardas.
How to design the earphone cable of EM 5813? It is very simple to talk about, it is the Litz wire, and then the twisted coaxial structure is arranged in a golden ratio. Not difficult? It's hard, because the wire structure of the EM 5813 is basically the same as the AKG headphone upgrade line that Cardas introduced before, but it must be made thinner, so it is more difficult to manufacture.
As I said before, the efficiency of the EM 5813 is good, and the iPhone can be pushed well, which means that you don't need to find a headphone amplifier for the EM 5813. However, we can't always be so sloppy. I use the Macbook Air as a source, plus the Meridian Explorer DAC and ear extension. EM 5813 this headset "very needs Run", when I just got it, it sounds disappointing, because the sound is very dark, high frequency does not have any vitality, call the agent, originally did not want to write, but the agent It is said that the line of Cardas headphones needs a long time to practice. Well, give EM 5813 a little more time and run slowly on another computer.

The wire of EM 5813 is thicker because the conductor adopts the Litz wire, and then the twisted coaxial structure is arranged with a golden ratio. It is naturally thick and strong, and of course the sound is better.

How long has Run been? Sorry, I really don't remember, but at least for more than a month, I will pick it up again. Well, much better, the high-frequency vitality is back, but the thick personality of EM 5813 is still not reduced. If you like full and thick sound, Then EM 5813 is sure to suit your taste, but if you prefer to be clear and transparent, sorry, EM 5813 is not your dish. Also, the EM 5813 comes with two earplugs, the white one is a closed design, the low frequency feels more, the blue one is semi-closed, and there are a few holes above, the low frequency sense will be less. Because the EM 5813 is a low-frequency headset, I used blue earbuds later.
I want to mention Barbara Burkle's album "Everything Allowed". The first track of "What A Difference A Day Makes (Cuando Vuelva A Tu Lado)" is not only a jazz standard song cover, but also a Spanish, very flavorful, jazz drum and The prelude of the piano has a thick performance on the EM 5813, and the sound density is good. The shape of the piano, the jazz drum and the saxophone are huge and heavy, and the sound of Barbara Burkle is thick and sweet. In short, EM 5813 has a warm, comfortable and thick texture that makes jazz more lazy.

The size of the earphone casing of the EM 5813 is not small because the diaphragm size is larger than that of the general in-ear earphone. It is said to be about the same size as the eardrum of the average person, so the size of the earphone casing also becomes larger. Talking about the low frequency, I also want to mention the "I couldn't hear nobody pray" album by Fairfield Four. The four boys Accalella sang "These Bones". The thick voice of the bass is very attractive on the EM 5813. Of course, because the high frequency of the EM 5813 is more convergent, you can't hear the details of the vocal recording “spouting water”, but the thick and vocal part of the male chorus is good, and the layering is quite good. This is listening to the Accapella a cappella chorus. The fun of listening, EM 5813 performed well in this part of the music.
As far as the sound is concerned, the EM 5813 is worth the money. It takes a warm and thick route. Some people may think that the treble is too convergent and too dark, but that is the personality of the EM 5813. However, the thick headphone cable is not easy to use with me. I tried to wear it on the MRT, but the peak time often worried that the headphone cable was ripped off by others. In addition, the earphone cable of EM 5813 is thick and heavy, and when the outermost cloth is rubbed, there will be some microphone effects, which will make it easier for the clothes and the earphone wire to rub, causing extra noise to be transmitted to the ear. inside. However, if you put the EM 5813 on the desktop, these problems will be much less.
Well, Cardas is a manufacturer of wire rods. Their "fever" definitely has their own attitude, but in any case, this EM 5813 is the first earphone of Cardas. The warm and thick personality is very obvious. They expect several models. The headset was subsequently released, and let us observe that this warm and thick, will be the common feature of Cardas in the design of headphones.
