Do you know how to make the most of your headphones?

How to fully exploit the potential of headphones? The headphone amplifier is usually the fastest path, with enough power to firmly control the headphone unit, but when you solve the headphone driver problem, the next upgrade method is probably the headphone cable.

The Duet headphone cord from Crystal Cable in the Netherlands is the first product of the Crystal Cable Portable, representing them in the outswing battle of listening to the market.

Portable wire new work

The appearance of Duet is not the same as the Crystal Cable we usually know, but the technology inside is the same. Crystal Cable's audio wire, like its name, is almost transparent, using a coaxial structure, the conductor is a signature gold and silver alloy wire, the wire does not take a thick line, but is made of high-strength PE material. A layer of isolation can reduce the capacitive reactance of the wire, but there is a slight change in the Duet. The conductor is the same gold and silver alloy, but the appearance becomes black and white, and the weaving is twisted, but the external approval is changed to medical treatment. Grade plastic, which is made of soft and durable material for action listening. In the center of the earphone cable, there is also a Crystal Cable decoration with the original serial number on it for verification.

Diversified earphone terminal specifications

Although Duet is a headphone cable, the terminal portion is slightly changed to become an RCA signal line. According to the different earphone terminals, Crystal Cable also provides the corresponding terminal selection. I get the IEM MMCX terminal. You can also purchase IEM 2-pin, 2.5mm TS, 3.5mm terminals, which are common standard terminals. Crystal Cable also offers Fomo Utopia-specific Lemo terminals, HD800-specific terminals, and Mini-XLR 4-pole terminals for Audeze. As for the terminals connected to the source, Crystal Cable has a variety of options, including 2.5mm, 3.5mm, 6.35mm standard headphone terminals, and the choice of balanced terminals is also available, including 4.4mm new specifications, 4-pole XLR or Double 3-pole XLR.

It’s dazzling, isn’t it? In fact, it is not difficult for consumers. If you are an HD800 user, you can buy HD800 dedicated terminals. They are even taken care of by Focal Utopia users and Audeze users. The earphone terminal looks at the ear extension. If you need to balance the output, Crystal Cable can be made according to your needs. However, such complicated input and output terminal specifications are available for selection, but it is difficult for the agent. In the end, how to order the specifications, the number of each should be under, it is really a problem.

Transparent, bright and wider

I got the Duet headphone cable, equipped with 3.5mm standard headphone terminal, using Japanese Oyaide high-end parts, and the connected earphone part is the standard MMCX. There are two earphones on the hand, one is Acoustune HS 1551 CU, one is Sony Just Ear XJE-MH2 custom headphones listen to samples, and Sony's own Kimber Cable headphone cable can be compared.

Sony XJE MH2 (I listened to the Listening version) the original earphone cable, obviously lost in the first round, if you plan to order XJE MH2 customized headset, upgrade the headset cable must have a clear feeling. As for the Acoustune headphone cable, Sony's Kimber Kable headphone cable and Duet, each has its own benefits, and Duet does have its obvious sound characteristics.

What kind of sound features? Deeper low frequency, more transparent mid-high frequency, cleaner and faster music transient response! But I am not saying that Duet defeated the other two headphone cables, but Duet has a distinct personality in these three parts. Acoustune and Kimber Kable are twisted braided lines, Acostune is the thickest, Kimber Kable is the thinnest, Duet is in the middle, Acoustune has the most low-frequency sense, the rock atmosphere is the highest, Kimber Kable band is balanced, the sound is soft and smooth, and Duet is in the sound. Winning on the brightness. So I said that the three lines are good, and the voices are different.

Sound transparency can be heard immediately

If you have a high level of sound transparency, then Duet may be the line you like. For example, the Japanese singer's jazz recording "Misty", with Duet and Acoustune HS 1551 CU headphones, is more transparent than the original cable, the sound is brighter, and the drum brush is more than audible. Duet fully demonstrates the beauty of the recording. When I switched to the original HS 1551 CU line, the thickness of the mid-low frequency was better, but the sharpness of the mid-high frequency was slightly worse than that of the Duet.

I don't want to say which line is better, because each has its own merits. How to choose it depends on the taste of your music: Duet is good at showing the tension and sharpness of music, while the original line of HS 1551 CU is the thickness of sound. Well, the low frequency is full and thick, Kimber Kable's voice wins in a balanced way, and the sound line is soft and smooth. These three lines are all good at winning, but the tonality and taste of the music are slightly different.

Make up the gorgeous feeling of medium and high frequency

The sound of the HS 1551 CU is tonal, and the mid-low frequency energy is quite strong. After the Duet, the mid-high frequency sound adds a sense of gorgeousness. Like listening to Bill Evans' "Waltz For Debby", "My Foolish Heart" is a live recording, and there is a small tavern background noise behind the jazz. When you pair with Duet, you won't miss these finely broken music details. Add a lively atmosphere of live recordings. Listening with the original line, the shape of the instrument is larger, the sound is thicker, and the details of the background cup are slightly different, which is also very interesting. However, if you like bright, sharp and rich music details, then Duet will not let you down.

Duet's low-frequency line is clear and fast, and the low-frequency dive extends naturally, like listening to the "Tricycle" album, the prelude of the electric piano, followed by the violent jazz drum, Duet uses the blasting low frequency Bright and expressive, full of impact, electric bass full of energy, clear note particles, bass Solo's musical skills, Duet clean and clear low-frequency performance, you can clearly hear the skills of the Bass hand.

Another example is Richie Lee Jones' "Pop Pop" album, listening to "Spring Can Realy Hang You Up Most", a prelude to the beginning of nylon guitar, Duet presents a clean plucking line, and Richie Lee Jones's voice is light and sweet. Lazy, sexy expression of the throat, listening to it with Duet is fascinating. Duet's low frequency also has good resolving power. You won't mistake Double Bass for electric bass, because the double burrs of Double Bass and the natural volume of Double Bass after plucking, the low frequency of detail is full Beef flavor, not electronic flavor.

Classical music verification texture improvement

For classical music lovers, Duet's natural mid-to-high frequency performance is definitely a plus for many upgrades. I talked about the slow movement of "Chopin's Piano Concerto No. 2" in the music lecture. I used the version of Pies. I used the HS 1551 CU to listen to the Duet headphone cable. The end of the piano is beautiful. After the theme is repeated, The octave repeats the theme, and the piano looks gorgeous and romantic.

And slow, I only recently Rip's album: the new version of Chopard Piano Competition Afdiyeva, immediately to a version comparison, the orchestra is an 18th century orchestra (retro), the sound does not have the Royal love of Pierce The orchestra is gorgeous, relatively simple and relatively rich, but Afudieva's piano, the speed is really romantic. What kind of speed is called romance? It is hesitant to 0.01 seconds when the expected note falls, and the note of the other hand is 0.01 seconds faster than the time you expect, sometimes hesitant, sometimes too impulsive, such expression is romantic. Duet's earphones have a clear musical resolving power, which allows me to immerse myself in Afdieeva's romantic feelings. I can't help but admire the champion of the Chopard Piano Competition, which is well-deserved!

A good choice for bandwidth, speed and detail

Although Duet is the first time that Crystal Cable has stepped into the mobile listening market, they have already made a name for themselves in the home audio market with gold-silver alloy and coaxial cable structure. One shot is a very high-quality headphone cable. In terms of music personality, Duet is very obvious. It is a bright and beautiful musical expression. It does not pursue volume in the low frequency, but an open bandwidth extension and a clean and slender speed. Duet is clearly a personalized headphone cable. For those who are looking for details, pursuing lines, pursuing bandwidth and speed, Duet is a headset upgrade line worth checking out.
