A short review of the Gewa headphones
The GEWA HP EIGHT and GEWA NINE-X headphones are the new releases from the German company Gewa, which specializes in producing musical equipment. The headphones belong to the "budget" class, but despite this, they are made quite well.
GEWA HP EIGHT and GEWA NINE-X headphones
The GEWA HP EIGHT model is a full-size closed-back headphone. They have an impedance of 32 Ohms and a frequency range of 10 Hz to 26 kHz. The cable length is 3 meters, type 3.5 mm stereo jack. The headphones come with a carrying bag.
The GEWA NINE-X is a full-size closed-back headphone. They have an impedance of 32 Ohms and a frequency range of 10 Hz to 28 kHz. Equipped with a detachable 3.5-meter cable and a 3.5 mm stereo jack. The headphones come with a carrying bag and two pairs of earpads (velour and leather).
The sound detail is good, and the frequency response is quite flat. There are no unpleasant resonances in their sound. The earpads of the GEWA HP EIGHT model are made of durable eco-leather. The GEWA NINE-X model comes with both leather and velour interchangeable earpads. In terms of sound and detail, the GEWA NINE-X model sounds better than the GEWA HP EIGHT model.

Sound without Realphones calibration.
GEWA HP EIGHT
The GEWA HP EIGHT headphones reproduce low frequencies well. The sound is natural but slightly "muffled" in the mid-high frequencies. The mid frequencies have a slightly "nasal" coloration. The dynamic transmission is good for headphones of this class.
GEWA NINE-X headphones
The GEWA NINE-X with leather earpads without calibration is less balanced than the HP EIGHT. The sound is even more "muffled." The low frequencies are deeper in the sub-low region. There is some excess in the low-middle region.

The GEWA NINE-X with velour earpads has a more balanced sound. Good low-frequency transmission. The mid frequencies are slightly colored. Very good detail in the high frequencies.

Sound after Realphones calibration.
The "muffled" sound in the high-mid region disappears from the GEWA HP EIGHT. The timbres become more precise. The virtual scene gains greater detail and openness.

The GEWA NINE-X with leather earpads. The timbres and spatial qualities improve significantly. The tonal balance is leveled out. You can hear many more details. The GEWA NINE-X with velour earpads. The softness and balance of the sound remain, but the timbres become more precise. The level of detail and spatial resolution is increasing.

Drawbacks of both models include the headphones being highly sensitive to the angle of the ear cups, which requires some attention when putting them on to achieve optimal sound.

We highly recommend the GEWA headphones as a durable model within its budget range. They are well-made and have a soft, smooth sound without the sharpness often associated with budget headphones. Additionally, they exhibit good detail and accurate tonality, along with strong dynamic characteristics, especially after calibration.
