Legend of the upgraded version of ----Astell & Kern Roxanne II headphones

In fact, during the tour of Jinan station, I had already touched the ROXANNE II headphones. Of course, JH Audio and Astell & Kern released "SIREN" earphones at the same time as LAYLA II, ANGIE II and ROSIE II. . It has been three months since the opportunity to seriously play the prototype.

Untold secrets

There is an old stalk here, I have been embarrassed to say it, Jinan audition activities, I help to replace these prototype 2.5mm balance line, due to the first contact with the four-core balance line and such a tall headphones, a time without start, So four plugs were found to be inserted into the four holes. As a result, just as the audition activity began, there were problems with the audiophile's response to the headphone sound and unilateral sound. Uncle (do not know the name of the origin of the name can see a set of underground traffic station) to find out, the original line of some headphones is reversed. In fact, A&K and JH released the headset, the unit did not mark around, but there is a practice, everyone as a potential rule is good, that is, the left side of the cavity for the AK's LOGO, the right side of the cavity for the JH's LOGO. In order to facilitate the docking of the wire with the earphone, there is a very fine semi-circular protrusion at the earphone socket, just like the circular groove of the wire pin. It's that simple, but I made such a low-level mistake. When I was scared, my face was green. If I hadn't had no mat or urine, my trousers would have to be scared. If so many machines were dismembered by me, how many kidneys would not be enough to pay.

Well, do not say gossip, first talk about ROXANNE II it, in fact, before the advent of LAYLA, ROXANNE should be regarded as the first headset SIREN series, JH is the most classic best-selling model, plainly, ROXANNE is JH24 --- global first A unilateral 12-unit headset, the best-selling model of Jerry Harvey's custom headphones, was also the choice of 80% of singers in the JH Audio customer base. The origin of ROXANNE's name is also quite interesting. JERRY HARVEY named the headset with a classic piece “ROXANNE” from THE POLICE. ROXANNE II is an upgraded version as its name suggests, and the second generation of products uses many new technologies.

 

JERRY HAVREY, UE, JH Audio

Although many fans know the history of the JH Audio brand and its brand founder JERRY HAVREY, but here still want to say a few words about the origin of his own and custom headphones. Before JERRY HARVEY was a tuner for Van Halen's VAN HALEN band, it is possible that few people now know about this band after 90s. Like someone who asked for BBKING and ERIC CLAPTON at an interactive event, many people are stunned. In fact, the reason is very simple. Different backgrounds have different backgrounds to create and popularize different music. Just like Cui Jian sang the red and the green with “nothing at all”, and the Chinese thought that the spirit of DAVID BOWIE was not as good as Cui Jian’s dregs, but everyone did not know that rock was something that DAVID BOWIE had played with 20 years ago. So, it doesn't matter if you don't know VAN HALEN. Say years, I really don't blame you. ~HIA HIA HIA HIA~

 

Van Halen is a famous rock band in the United States in the 1980s. The soul of the band is ALEX VAN HALEN. At the time, he complained to the band's tuner JERRY HARVEY that stage noise (both rock, industry, death, noise... everyone knows) made his hearing worse and worse on the stage. It is difficult to hear the beats and accompaniment of other players. So JERRY began to develop and help ALEX VAN HALEN to make the first pair of custom dual-unit in-ear monitor headphones. This headset reduces the stage noise's damage to ALEX hearing and allows him to clearly understand the beats of his teammates. Then one out of control, we all know that many times a good product is passed on from word of mouth. Afterwards, more and more customizations are required. JERRY established ULTIMATE EARS (UE) in 1995 and became the founder of custom earphones. In 2007, Logitech acquired UE at a cost of US$34 million. However, the story did not end. JERRY started the JH Audio program again and did a good job. Nowadays, few people seem to customize the headset of the UE. I just want to hide that someone sells the company and has established a new company. In less than 10 years, the old company acquired by others has abused his body. Of course, JERRY HARVEY and UE have also created a lot of glory, and brought us classic headset models such as TF10, UE10PRO, and 11PRO.

 

External and Inner Design of ROXANNE II Design

The SERIN series is a product series jointly released by Astell & Kern and JH Audio. Naturally, AK does not need much space to introduce it. In recent years, a benchmark product in the HIFI player industry has been the best in the HIFI industry. SERIN is not a custom headset, but it should be regarded as a public model of custom headphones, but these public models in the design, texture and internal structure and other issues than previous products have no small updates and upgrades, and even some reborn feeling.

 

The ROXANNE II packaging is not included here. The accessories can be mentioned because JH's metal cans are really beautiful. Of course, as a joint release of the two companies, JH SERIN series and AK player can naturally be perfectly bundled and combined, so ROXANNE II headphones in addition to the 3.5MM headphone cable is also equipped with a 2.5MM interface balance line, we can With AK380, AK320 and other flagship flagship products to experience ROXANNE II balanced output music charm. As mentioned in the opening chapter, the ROXANNE II uses a four-pin socket design with a link between the aluminum counter-rotation wire and the headphones. This connection is stronger and more reliable than the SHURE pin.

 

On the wire, a low-frequency controller is placed near the plug 15CM, and it is equipped with JHAudio's unique low-frequency compensation technology, which can be raised from 0dB to a maximum of 13dB in the 10 to 100Hz frequency band. You can adjust the low frequency according to your own taste as if you were eating instant noodles in accordance with your own taste. Although this sentence is circumstantial, it is believed that most people who pass the language can understand it. The ROXANNE II headset has a dedicated screwdriver that can be used to easily and precisely adjust the low frequencies. Of course, if you don't have a screwdriver, you don't have to worry about it. When I'm out on the street listening to music, if I feel that the low frequency is so explosive, I will carry it with me. The Swiss army knife above the small screwdriver to adjust.

 

The headphone cavity has been improved from the previous generation by FULL METAL JACKETS (full metal shell). Of course, LAYLA II is made of titanium alloy shell. ROXANNE II uses the same aluminum shell as ANGIE II and ROSIE II, including headphones. The wire interface also uses a metal snap. Headphone cavity using carbon fiber back plate, like Zuo Qinglong right white tiger old cattle in the waist, hey, etc., what about the old cow? ... ROXANNE II has no cows, only left AK right JH two iconic logo. Black carbon fiber back plate with red LOGO, it is very bright.

 

ROXANNE II is equipped with soundrIVe technology, and has the latest patented mini quad drivers on the speaker unit, namely JERRY's exclusive custom four-unit composite unit. This design effectively reduces the size of the multi-unit headphones and brings them to Roxanne II. More extensive frequency response and ultimate sound. Therefore, we say that the unilateral twelve-unit structure—four low, four middle, and four high—is actually three composite moving iron units. This is the product packaging and QUAD LOW, QUAD MID, QUAD HIGH above. Of course, these are JERRY's exclusive customized units, and other brands of multi-unit moving iron headphones are not equipped with this unit.

 

The ROXANNE II headset uses FreqPhase technology with a stainless steel catheter to minimize the phase error generated between different speaker units, allowing the signal to reach the ear in less than 0.01 milliseconds.

Of course, some people will say that LAYLA II is better or better than it, but it cannot shake the legendary status of ROXANNE II and JH 24.

Talk about sound

Naturally with AK380 to listen, low frequency I adjusted to the middle position, volume 80, with 2.5mm balance line.

Low frequency

Why do I like to adjust the knob of the low frequency regulator to the middle position? Because I clearly remember that the ROXANNE II gave me a feeling of low-pitching, but the overall sound is not transparent enough, I think a top headphones sound should not be the case, and later found that the original low-frequency regulator knob is the largest in the tour activities Volume position. In fact, even if the ROXANNE II's low frequency is halved, it can still clearly feel its excellent dive, strength and abundance of low-frequency volume sense. For listening to SWING JAZZ, rock and other still have a great sense of music and emotional expression. The low-frequency composite unit brings outstanding dynamic performance, a sense of enthusiasm and quantity, and the transient advantage of the moving iron unit itself is also reflected. Have a good sense of speed and flexibility. ROXANNE II is really suitable for listening to rhythmic music. If only used to listen to saxophone, big bass these instruments, low-frequency dense and full texture and the harmonic performance of the pipe string is very good, and has excellent control.

Intermediate frequency

With vocal positioning science, you can't hear a 400X engineering machine sinking in the end, and you won't feel the FX1200's ear-like vocals. Of course, this may exaggerate some, but the positioning is not biased in my opinion. . The meticulousness of the vocals was excellent. I had heard of a unilateral eight-unit headset. The vocal details were very numerous, but the female voice was occasionally too bright. The ROXANNE II's female voice has excellent brightness, but this brightness does have the delicate and delicate sound details to support. Without partiality, the sound of male female voices is maximally restored. Voices can be used, natural, delicate, full, bright and beautiful to describe it. In fact, I will not tell you that the small-scale classical, unplugged and so very nice.

high frequency

In the beginning, he said that ROXANNE II was boring and not transparent, but the reason was very clear. In fact, the low-frequency regulator fully rushed to grab the limelight. Adjusting the low frequencies appropriately, the ROXANNE II's brightness is highlighted. Even if the low frequency regulator is adjusted to the middle position, ROXANNE II as a moving iron headset, good transient performance and ample amount of information to enrich the thin and transparent high frequency performance of this headset. The vocal tooth tone with the AK380 is also very natural and slightly unobtrusive. The harmonics of these instruments, such as piano, violin, flute, and triangle, are fascinating and shrink.

Even with the low-frequency verb Daci, the rich detail of ROXANNE II still runs through the entire sound spectrum. The excellent resolution and sound details allow any musical instrument and vocal to come. Of course, the sound field has become a weakness. For example, when I listened to the Dance of Jugglers, the entire composition of the song is very structured, the instrument is clearly positioned, and the distinct and delicate layering is expressed. It can be said that one can hear the charm of this legendary headphone, but the sound field is cramped. Something even if I use 2.5mm balanced output. We can define ROXANNE II as a king. There is a general trend, but there are still deficiencies.

The last few words

ROXANNE II is the second flagship of the SIREN series. The price of 13888 is prohibitive for most fans. Although it still has its shortcomings, although it is not the most flagship model, the existence of ROXANNE II is a legend. The continuation of the world’s first unilateral 12-unit moving iron earphone JH24 is the goal pursued by 80% of the JH Audio customers. It takes the ultimate quality of a flagship headset to its fullest, and uses an adjustable low frequency to improve the overall sound style of JH custom headphones for stage monitoring, allowing users to get the sound they want. Using it to enjoy rock, pop, JAZZ, SWING, Nation, small classical music and other types will give you the ultimate performance. And do not 88, not 888, not 8888, as long as 13888, local tyrants can use it to please their ears.
