The rounded, acorn-like design of both Balance and Brass is the same as the original Co-Donguri. Resonance is suppressed by adopting brass, and it is said that it "reproduces clear and tight bass". When you put it on your hand, it's a little heavier than the original Co-Donguri.
The driver is a dynamic type with a diameter of 10 mm, and it is said that it can suppress the masking phenomenon of the high range by combining the unique technology "Tornado Equalizer" and reproduce the high range of 10 kHz or higher. The frequency response is 5Hz to 40kHz, and supports high resolution playback. The output sound pressure level is 106dB/mW, and the impedance is 18Ω.
The part that hits the fruit is painted with a metallic paint that suppresses the gloss and has fine unevenness. ). Brass will be available in two colors, Bordeaux and Noir.
Brass is used for the metal parts of the housingFirst, connect unbalanced brass to the AK70 MKII (actual price: about 70,000 yen) and listen to the Eagles' "Hotel California" (192kHz/24bit). At the beginning of use, the sound tends to be sloppy, which is common with low-priced earphones, but after a few days of use, the overall balance has settled down and the way you hear it changes. The mid-high range is thick, and you can feel the attack of the bass and drums.
Unbalanced "Co-Donguri Brass" with Bordeaux colorNext, replace it with Balance and listen to the same song. Since the earphone part is common, the sound tendency is similar to Brass, but there is no feeling of stuffing or blockage of sound, and the sound field is vast and the effect of balanced connection is clearly reflected in the sound. I also liked the width of the sound field of the original Co-Donguri, but when I listened to it again, the Balance sounded more spacious. Judging from the cuteness and affordability of the appearance, it is an unexpected impression that the sound with such a sense of depth comes out.
The amount of information in the sound has increased significantly, and the separation of individual sounds has also improved. The vocals, bass, and drums sounded three-dimensional, and this trend was particularly noticeable around 3:30 to 4 minutes of the song. The power of the sound has increased and it sounds more powerful, and the volume (80) that I felt was just right when I listened to it in Brass is fully felt at 73rd place in Balance.
On Balance, I was particularly comfortable listening to Akira Jinbo's instrumental song "Blowin' in the Street" (96kHz/24bit), which has an impressive saxophone sound and powerful drums, and a relaxed singing style in the waves. Yanagi Nagi's "Aqua Terrarium" (same as above) with a melody that seems to sway. Calm jazz, fusion, and songs with female vocals are easy to get hooked on.
However, depending on the genre of music, it may not match. For example, in heavy rock, classical music, and large orchestral music such as movie soundtracks, the high frequencies of hi-hats and cymbals can be hard on your ears. Also, the sound of stringed instruments sounds rough, so I wanted it to sound a little more.
The previous SpinFit earbuds were made of hard material, and I personally didn't feel comfortable with them, but the new model changed to the soft Final E type, which made it fit better. maybe one. While there is moderate sound insulation, you can still hear outside sounds, and the sound leakage is almost unnoticeable. It will come in handy on trains when commuting to work or school.
The charm of the Co-Donguri series is not only the sound but also the ease of handling the cables. Balance and Brass use an OFC litz wire 4-core "spiral cord" that can be hung down and worn normally, or worn over the ears like a Shure hook. Thanks to the many thin grooves on the surface of the soft material, it won't get tangled even if you accidentally bundle it up or put it in your pocket carelessly.
Both Balance and Brass use an OFC litz wire 4-core "spiral cord"The Co-Donguri Balance cable is directly attached and cannot be replaced. However, it can be said that it is a unique feature that you can enjoy the charm of balanced connection at a reasonable price than buying a replacement cable. In the past, TTR also exhibited a re-cable version of Co-Donguri at events such as the headphone festival, but they have no plans to commercialize it at this time.
Co-Donguri Balance realized the maniac way of enjoying earphones called balanced connection for about 4,600 yen. Not only is it reasonably priced, the sound is highly satisfying, and you can fully enjoy the benefits of balanced connections. There are strengths and weaknesses in the genre of music that sounds, but if the individuality of the sound and the tendency of the sound source you like match, it will be a product you can't do without. It is a product that I would like people who say "I have a balanced player, but I listen with unbalanced earphones/headphones" to listen to it.
