First impression
This time, we will check the first impression using the largest size of silicon in the ear tip of the package.
A drum with a strong attack for rock, not competing with the bass, a tight hi-hat（Yorushika - "Bloom in that summer"）
One of the features of this earphone is in the rhythm part. I listened to "Bloom in that summer" by Yorushika.
The first thing you notice immediately is that the drum has a strong attack, but it has a resilient sound that emphasizes the tenacious leatheriness and makes it feel like firepower. The punching sound is strong and you can hear the rhythm firmly. The kick is clear without colliding with the base, and lithely steps in, giving a slightly raised feeling. There is a lively feeling on the whole, and it is a bouncing sound suitable for rock like this song and pops. Higher frequencies roll off much faster, so the brightness is less emphasized. The drum sound doesn't get too bright, so it feels tight.
Next is the hi-hat. The shaft is not very upright and the spearhead is not high. The attack is not bad and has a tight atmosphere, but the height is suppressed and the spread of air feeling is suppressed. The sound seems to be leaning toward the lower part of the high frequency range, and has a rather rusty atmosphere. Rather, it is a drive sound similar to a ride cymbal, which is a tough sound that emphasizes the hard and heavy feeling and suppresses the flashiness.
Personally, the rhythm part of this earphone is very tight, lively and cool. The hi-hat, which is quiet and rusted without emphasizing height, but is driven firmly, makes the drum sound more dynamic by not being too conspicuous. Similarly, it's less noticeable than vocals, so it doesn't disturb them. If you like tight rhythms, the rhythmic expression of this pair will sound comfortable.
A warm, slightly colored, beautiful arpeggio acoustic guitar with good coloring, clean and sweet vocals（Eri Sasaki - “Winter Weather”）
If you like sing with playing acoustic guitar, you may love this earphone. The arpeggio sounds beautifully in a warm atmosphere, while the high frequencies are suppressed and the glitter is adjusted to a natural ferling. For example, let's listen to “Winter Weather” by Eri Sasaki.
The color of the acoustic guitar is close to gold and you can feel a slight warmth, but there is also a sense of cleanliness in the high range, so it is not too rich and refreshing, but the sparkle is not strong, so it sounds sweet and gentle. The arpeggio sounds singly and soundly, so the graininess is solid and should satisfy acoustic guitar sound lovers. Although not emphasized, it has a moderately moist, not a dry, and a fulfilling feeling.
Vocals have a clear sweetness as well. Breathing is slightly emphasized, but consonant emphasis is not strong. It gives the song a unique, warm fuzzy feel while keeping the breath clean. Sweetness and refreshing feeling coexist well.
I think that the acoustic guitar and vocal atmosphere of this earphone is suitable for such a song. Guitars and vocals with good detail, both with sharp edges and breaths, are not too bright and do not feel too high, so they are sweet and mellifluous. It will give a nostalgic atmosphere.
Mellifluous sound image expression without distortion that is not too miniature（Rasmus Faber - "We Laugh We Dance We Cry"）
Since the high frequencies are not open to the high, the EDM is a sound that emphasizes the sound image, where the sound is too disassembled and does not feel jagged, but rather calms down on the precise details. When you listen to EDM, there is almost no feeling of swoosh in the high frequencies.
In the case of earphones that emphasize the high range, listening to the EDM track tends to produce a squeaking noise, but this earphone suppresses the high part of the high frequency, so it does not feel squeaky. For this reason, the sound image in the mid-high range is carefully resolved and pushed out, and the detail is easy to hear.
The floor has good punches and is tight and agile, so it feels good to speed.
Fresh pop music with speed and sweetness（Nao Touyama - "Imakoko"）
This earphone has been confirmed to have a vibrant drum with a solid sense of speed, good vocal focus, and a good graininess and sweetness that makes the arpeggio of an acoustic guitar sound beautiful. Such atmosphere seems to be suitable for a song like "Imakoko" by Nao Touyama.
The drums are powerful and moderately attacking, yet they have agility that sounds tight, so they can express the speed of this song without delay. Acoustic guitar is a golden, sweet sound that is not too noticeable, mild, but has a solid arpeggio. The hi-hat's graininess is good and you can hear it crackling finely, but it does not shooy out high, so the flashiness is suppressed and there is a sense of transparency, it does not disturb the glossy piano line and vocals.
The vocals are sweet, they have a sultry feel and have a coquettish feel, but they breathe well and are cheerful but they don't stretch too high, so they have a moist atmosphere. The consonants are not sharp and the sibilance does not stab, so there is nothing hard to hear.
Summary
This time I checked the sound quality impression of TANCHJIM Oxygen. Despite being slightly elaborate, it has a well-balanced, flat overall, powerful rhythm with good attack, good vocal focus, and the sound is sweet and warm. Well tuned, it sounds versatile. It's a great recommendation for those who want to feel the dynamism of the drums and those who want to hear the acoustic guitar in a beautiful and sweet form.
