Gold ratio deployment of Cardas Cardas EM5813 headphones audition

In 1987, George Cardas founded Cardas Audio, which is known for its wire and components. Cardas solved many problems on the transmission line with golden ratio resonance technology and materials, and designed and manufactured high-quality High-End wire.

In the fourth quarter of this year, Cardas launched its first earphone product, the EM5813. In the old line of Cardas, the use of its own wire for headphones is definitely a big selling point. Looking at the thickness of the headphone cable, you can intuitively feel the solidity of the materials. It is very rare to use such a thick wire in an in-ear earphone. The headphone cable uses its own Clear Light Headphone Cable, which uses a coaxial paired structure.

The Polymethazine used in Japan is made of Polyethylene Naphthalate. Plus the 11.5mm moving coil unit, yes, 11.5mm for the in-ear type is a fairly large drive unit, this size is similar to the size of the human eardrum. The earphone casing is then coated with an alloy custom-made from Europe and the United States. The overall weight is quite heavy in terms of headphones, from the wire to the earphone itself is heavy. Cardas has a special feature that attaches great importance to the golden ratio. Whether it is from outer packaging to earphones or wire, the proportion of gold is used to adjust the size, length and width.

The EM5813 is a low-impedance (32 ohm) design. The most important thing about this design is that it is easy to drive. The target is definitely on a mobile device such as a smartphone. Not only is it easy to drive, but it is also specially designed for the connected terminal heads, even if it has a protective case. The entire combination also includes two different sets of earplugs, one with a strong sense of low frequency and the other with a hole for the earplugs, suitable for users who do not like too much low frequency energy.

I tried this headset that should be quite good for a while, I feel that the weight of the headset body is really full, and the weight of the headphone cable makes me feel a lot of curiosity about its sound. What can be done with in-ear headphones?

I took the previously published HM-700 as a sound source and listened to what effect this new combination would have. The earphones that were previously paired are RE-400. Of course, these two headphones are not at the same level. It doesn't make sense to compare these two headphones, so I believe that changing to EM 5813 is definitely a new experience.

The first feeling after playing is that the bass is quite abundant. Although the 11.5mm unit is very large, the speed is still dexterous. The endless bass and speed are particularly enjoyable in listening to rhythm and strong songs. In some songs There will even be obvious sound pressure. The voice line is a fat, thick, and hobbyist who likes to listen to a singer with a strong lung capacity or a low voice, even with a hoarse voice, should be very satisfied. But because of its distinctive features, it may have different feelings when playing fresh vocals or slender songs.

This is a low-impedance earphone, of course, the purpose is to allow users to choose a sound source with a wider width, not limited to more professional audio equipment. It's okay to connect a smartphone or a laptop. Younger generations prefer to listen to some rhythmic music, and use this headset to match the music signals available everywhere to quickly meet the needs of users. Not only is it convenient but also great music fun.
