  • requency responce: 4hz-40khz

Unboxing

The overall design of the earphone package is very simple, but not cheap. Rather, it has the atmosphere of a professional product that is elegant.

 

The build of the main body is simple, but it has a functional aesthetic sense and quality that is different from consumer products because it is a product that suppresses the flashiness of the atmosphere such as professional grade.

Fit

It fits well in the ear and feels good to wear. Please note that the sound insulation and sound leakage resistance are a little low.

This is a surprisingly flat sound that is flat from the mid-range to the mid-high range, slightly higher in the high range, and full of low frequencies. Strictly, it is a U shape, but the flat part is long, so the sound is infinitely close to the monitor flat. Since there are a lot of low frequencies, I think that you get the impression that you are listening to sound with closed-back monitor headphones.

The sound field is bright, the visiblity is excellent, almost all sounds are heard, and they are faithful to the sound source. If you are looking for a sound with high fidelity in the monitor sense, you should definitely buy it first.

 

The sound gives you the versatility of listening to sound in a mixing room of a recording studio using professional gear.

 

*Highly recommended as a standard earphone for listening to my blog's "Recording Signature".

The music used in the recording signature is from the game maker Nippon Falcom, which I love.

Final verdict

Comprehensive evaluation: ★★★★★

If you want to know quickly what sound is faithful to the sound source in terms of acoustic engineering, buy this earphone. Anyway, you can enjoy the feeling that you can grasp all parts of the sound source.
