Image of frequency characteristics (Test operation)


※The "Image of frequency characteristics" is a reference information for the purpose of reviewing the image of the frequency distribution personally for the sake of review. The measurement method and the measured data are very rough and lack strict reliability and accuracy.


Recording Signature (Test operation)

The recording signature is binaural, but of poor quality. The lows are easier to get out of, so I raise the lows with an equalizer, but still not enough. Therefore, it is different from the sound quality as it is heard, so please use it as reference information only.

First impression

With an impedance of 38 ohms, I thought it would be hard to sound with a smartphone in terms of sensitivity, but when I sounded it with the Galaxy A30, it was not unexpectedly bad. However, I still feel a little stunned. Well, if you enjoy headphones of this class, it is better to play them with DAP or through an amplifier.


Heartful space where fresh female vocals and transparent and glossy instrument sounds are heard in a sweet atmosphere (Karen from BEST FRIENDS! - "Ai de Afureteiru")



Personally, as soon as I heard this song on Edition 8 EX, I was deeply moved and shook. Because these headphones are closed in the high part of the high frequency range, they allow you to hear plenty of sweet sound. While adjusting so that the clue is felt in the middle and high range, the sharpness becomes stronger and the sound becomes brittle in the high range. In order not to lose the crispness of the sound image, it is seasoned with emphasis on transparency so that the sound can be heard with glossy particles with contours. The instrument achieves a mid-range with a substantial sense of realism, and has a thickness that gives a firm feeling of tension and volume, and the sound does not become thin and does not lose its richness. In addition, the depth is realized to give a natural three-dimensional effect to the midrange. The overall picture of the music is stable, with a firm foot in the midrange. The lows feel a little bulging, but they don't bulge too much and don't give too much weight. Therefore, it is seasoned so that the mids are well lifted, but the floor can be heard even in deep places.


For this reason, such sweet pops are particularly beautiful and moist. The space is colored in a sepia color close to pink, the gloss is fully felt, and the clear and transparent sound is a bit nostalgic. For example, the vocal of this song is sweet and has no sharp consonants, but it is a highly sensual expression that has a slightly rich and coquettish luster, a little longer breathing and a transparent feeling. There is an erotic like a painted glossy lip.


The sound of the instrument is not separated from the vocals, and it has a good sense of distance as a whole, yet plays a sound that is thick and glossy. However, as mentioned above, the clue is solid, so the synthesizer's tone has a clear outline separated from the space, there is no blurry feeling, and the gloss of the sound is drawn out sharply. However, the tone has enough sweetness that it does not sound digital and tasteless, but rather has the warmth of human skin.


Strings emphasize the overtones a little, but they have a sweet luster and are not hysterical, but rather smelling. Here is a beautiful sounding space that sings the melody of the whole music.


Sexy rock sound that smells glossy(Anzen Chitai - "1991nen karano Keikoku")



If you want to listen to this song in an erotic atmosphere, it might be the best companion. This song that you listen to with these headphones does not have the depth of hard rock and has no serious feeling, so you may feel the message nature of this song is sparse. The guitar is not black, but rather shiny and colored, and the vocals are sexy and rather soft.


However, the sweet sighs of the vocals and the erotic sweetness of the instrument sounds have a very glossy, dreamy taste as if you were enjoying a rendezvous of a floating world moment. If you want to listen to a beautiful and sensual rock, few headphones will make such a sound.


Colored space, glossy and coquettish vocals, sensual orchestral music with gorgeous smell (Seiko Tomizawa - "5-fun Dake no Wagamama")



The whole space is shiny and very sweet. The vocal is very sweet, fascinating and sensual, as I've talked about a lot, so let's keep it aside, but the one we want to emphasize in this song is the brass. The strings also had a gorgeous atmosphere, but the sound of the brass was even more flavorful, and just by hearing the sound, the whole music flourished, and there was a very moody groove feeling. It seems to be especially compatible with songs that value this mood.


A fresh and moist space (Yui Horie - "Hikari no Umi he")



The sound with a glossy and sweet atmosphere will give you a very fulfilling moisture in such songs. Acoustic guitars are finely engraved because the particles are beautiful, but the rich midrange does not thirst, which sounds like splashing water, and the hi-hat also blows up like a spring. The piano sound also has a shiny and moist feeling, and the sound effect of water is well moistened and sounds vivid.


If you like the fresh and moist sound, this headphone should never be missed. I? Of course, I love the feeling of moisture, so I fell in love at first sight. 



If you like the sensual, sweet and moist sound, you can't miss this headphone. Pop, rock, dance, jazz. If you want to enjoy the dreamy music of the dawnless spring full of flower scent, this headphone is one of the best companion. Let's enjoy the dreamy sweet moment that doesn't know dawn. There is singing music here, like honey, the source of life.
