Did Sendy Audio make a planar magnetic headphone AIVA out of rosewood?
As a child who has been dealing with
rosewood since childhood, taking a nap and doing homework in the pile of
finished wood furniture, any wood related products can always catch my eye at
the first time. Before moving, I also chose rosewood products for my bed,
wardrobe, bookcase and desk. As an ordinary family, I can also see my love for
As an audio enthusiast, I'm very glad to
see valuable wood used in products, because people who understand wood will
know the concept of "rosewood nurtures people". The more frequent
people come near and touch the place, the more natural luster they will feel. A
headset made of good wood can be wrapped like a bracelet. Maybe it's hard to
see. Although rosewood sounds valuable, it is actually a very suitable thing to
use. Of course, although I like wood products, especially rosewood, the wood
used by the protagonist of this article does not belong to rosewood. The
specific reasons are explained below.
When it comes to the brand of Sendy, the
only previous product of Sendy, namely the m1221 with coaxial ring iron
structure, has a good reputation in the market. From the actual performance and
final pricing, it is not difficult to see that Sendy is also a down-to-earth
manufacturer that takes the cost-effective route, but will not shrink in all
aspects (wearing, workmanship, packaging accessories, etc.), while the planar
diaphragm headphone "black beauty" series I believe you have heard a
little about it during the Guangzhou Exhibition in September. The protagonist
of this article is the headphone, which is called AIVA. It's a headphone that I
like very much when I first listen to it.
First of all, let's be clear. Zebra wood
and ebony wood used in the two headphones of black beauty series are not the
types of rosewood in the national standard. However, since I was a child,
because my mother worked with rosewood, I learned that many of the wood
products sold in rosewood stores cannot be regarded as rosewood in principle,
but a considerable part of the materials are of high quality（In terms of physical properties）, raw
material prices and processing difficulty, it even surpasses rosewood.
AIVA uses zebra wood. When I took the headphone
home, my mother and I mistook it for a kind of black wood. But after a closer
look, we found that the unique fine and uniform texture of the spotted horse
wood. What's more, the texture in my hand is just the same as the circular
direction of the cavity. It's not too much to say that it's the best. Zebra
wood is hard and difficult to process, but it doesn't have stable physical
properties like rosewood. If it's not processed properly, it's not only easy to
crack in too dry and damp environment, but also may fade after a long time. Therefore,
processing zebra wood as a daily product like earphone is "self
abuse" in order to maintain the stability of its wood properties Class, so
limited to 99 sets of this kind of operation, I am familiar with this kind of
wood and is very easy to understand.
Of course, the most important thing for a
headset is fitting. In this aspect, Sendy headphone is quite meticulous. The
first is the design of the headband. The soft headband at the top is made of
lambskin. The surface base contacting the head is large enough, and the
telescopic frame is infinite, which means that there is no sense of paragraph.
The moderate damping makes it very easy to adjust.
In addition, the ear cup, nicknamed
"little butt", is a shape measured by the human face. It fits and
covers the ear more closely. If it is worn firmly, it can retain the sound
details to a greater extent. Moreover, for this kind of open structure headset,
it is also the guarantee of low-frequency cohesion.
The wire plug is the same 2.5mm port as
he400i, which is a pity. If it is 3.5mm, it will be much more convenient to
purchase upgrade cable in the future. There are two original standard wires,
which are 3.5 single ended (oxygen free copper) and 4.4 balanced port (single
crystal copper). Users can purchase 2.5 and XLR balanced wires according to
their own needs. The Y connection area is also made of wood with Sendy Audio
Knowing that many of you can't wait, I'll
get to the point.
The headphone with flat diaphragm is hard
to drive in everyone's impression, but the sensitivity of AIVA is 96dB, which
is higher than that of he400i. In actual performance, I think that a Chinese
player with strong and thick sound or a normal volume headphone can give play
to the level of about 50-70%, while Chinese player flagship like PAW6000 and N8
are different. And different from the earphones, I prefer the balance port in
the headphone, so the sense of hearing in this paper is basically based on the
interface between 4.4 and XLR. Although the equipment I used to match may not
be able to bring AIVA's potential into full play, considering its sensitivity
and price, it should have a certain reference value.
Testing equipment: PAW6000 (4.4), A100
earphone (4.4), dx150 + amp8 (4.4). I will not specifically describe the sound
details of different front ends, but summarize the overall quality performance
and style trend of AIVA according to my familiarity with the front end.
As I have already said in the Central China
Exhibition and Beijing BAE exhibition, AIVA's timbre is ear catching, and it is
easy to be attacked by poison when listening to vocal music. This kind of
poison neither creates the sweetness of female voice by pulling the image lines
very thin, nor increases the thickness and grain sense to make male voice
become vicissitudes. First of all, it is certain that AIVA's medium frequency
has a certain thickness, and the details are extremely abundant, at the same
time, there will be no audible dental sound.
The toxicity of human voice is mainly due
to the relatively moderate tone dye, and the density is not high enough to have
a sense of oppression. When listening to clean and sweet female voices like
Chen Jieyi and Xu Jiaying, they will feel much immersed. As a price, when
listening to Zhang Yu's live in 2014, his voice seems to be young to the period
of "good intentions" in 1993. This feeling is in the delicate voice
of A100 and S6. Metrosexual man's voice is just perfect. Aiva's male voice
still has its own unique flavor. Unlike Grado’s passion and Audio-Technica’s
charm, it is probably "warm" just to sum up.
As an open back headphone, AIVA's
low-frequency performance has actually exceeded my expectations. It has a
moderate sense of quantity, which does not reach the level of moving times.
However, its texture is very similar to that of moving circles: the natural and
abundant residual sound sets off the sense of atmosphere. It has depth, but it
will not affect the diving of transient and large dynamic performance. The
high-density image is very important in the performance of cello high
transparency and analytical power. AIVA's low frequency can be said to have the
high quality of planar magnetic headphone. At the same time, its timbre
performance is not inferior to that of traditional dynamic headphones. In this
aspect, it even surpasses Ananda, whose price is twice as high as Aiva, and is
very close to my favorite hp-3.
When describing the low frequency, my list
just cuts to the cello playing version of misty rain by Mr. Jiang Lixing.
Although it is a cello repertoire, there are still many Violin and string
elements in it. It is not difficult to see that AIVA has many similarities in
high and low frequency. AIVA's high-frequency transient is very good, but it
doesn't seem sharp and energetic. The result is as solid as medium frequency,
but slightly soft. With high transparency, it is delicate in the treatment of
overtones, which is a kind of eloquent feeling. Although it sounds like it
conflicts with transient, it may be the charm of metaphysics. AIVA's
high-frequency overtone is very confident and elegant, just like the low
frequency. On the basis of not seeing the deterioration of quality, it
maximizes the degree of relaxation.
AIVA also benefits from the open-back
design. The scale and openness of the sound field are excellent. If you want to
talk about the relatively shortcoming, here is a collocation problem. If your
front end is a solid front end made by the middle frequency like the dp100, the
horizontal separation will be more crowded. Because the image of AIVA itself is
not slender, this collocation will be a certain amount of superposition. It is
just like the feeling of 100 O'Neill and 100 Guo Jingming standing on the same
stag is completely different. There are similar problems when they are used
together with S6, who usually performs well in the sound field.
When I first heard it, I was really
attracted by the medium frequency. However, when I analyzed the details of
AIVA's voice from the perspective of evaluation, I found that its three
frequencies have a very high degree of completion, strong analytical power and
dynamic performance. It is a loose and durable tuning trend. However, its
excellent two-end extension and dynamic performance make it more popular in
listening to classic and large-scale OST. It's a high-quality planar magnetic
headphone with this price range. Except for ACG burning songs, cute music, and
European and American rock, it's good to listen to everything, especially
female voices and folk songs.
The words of mastery spirit have been said
rotten, and its meaning is even changed in the past two years. From the perspective
of products, I still want to put it here as my summary of AIVA. Besides mastery
spirit, it is the original intention of hifi brand. I believe that in the
course of AIVA's birth, Sendy has more strict requirements for sound quality than
craftsmanship. No matter the meaning of this limited number of 99 pairs is to
make money or make friends, it is a sentence for users: "products speak
louder than words".
