Type
Over Ear

Type

Over Ear

Headphones with larger ear cups compared to on-ear headphones, which hug the ears.


They are more comfortable and provide better external noise isolation, but are more difficult to transport due to their larger size.

Generally, over-ear headphones can offer higher quality sound and deep bass compared to on-ear headphones of similar quality, thanks to their larger speakers.
Frequency Response
18 - 20000 Hz

Frequency Response

The range of frequencies that headphones can reproduce. The most common range is that of human hearing, 20 - 20000 Hz. A wider frequency range does not necessarily mean better sound quality.

  • (Bass) 20-250 Hz: Stronger bass, for depth. Ideal frequencies for listening to electronic or hip hop music.
  • (Mids) 250-4,000 Hz: The mid frequencies are stronger, suitable for better listening to vocals or orchestral music.
  • (Treble) 4,000-20,000 Hz: High frequencies affect the clarity and sharpness of the sound, for better listening to, for example, cymbals or the plucking of classical guitar strings.
Impendance
18 ohm

Impendance

The resistance that the speakers of headphones have to electric current. Usually, the lower the resistance, the louder the headphones sound, but the sound is less clear.

This size does not concern the average user as almost all headphones are 32 Ohms. Headphones with high resistance usually require an additional amplifier.
Sensitivity
120 dB

Sensitivity

The greater the sensitivity of the headphones, the louder they will sound at a specific volume of the source. Generally, values above 90db are considered very good. - **Above 100db**: Headphones with high Sensitivity produce more sound with less power. They can reach high volumes with low-power devices (e.g., mobile phone, laptop). - **Below 100db**: Headphones with low Sensitivity require more power to reach the same volume levels, so they may need a special headphone amplifier
Driver Diameter
32 mm

Driver Diameter

The diameter of the headphones' speakers. Usually, the larger the diameter, the more powerful sound with full bass they can offer.

    The cable plug for the headphone slot is not the classic mini jack but much smaller, resulting in you not having the opportunity to use a commercial one in case it breaks, but having to find the specific one from the company.

    Very good and clear sound, very good microphone, very good noise canceling. It says that they are over-ear headphones but they are not exactly over-ear. They sit on the ears. You need to have very small ears for them to fit properly. After many hours of use, they are a bit tiring. You have to readjust them a bit on your ears so they don't press down on your ears and head from the top. If you do that, they are fine. For their price (~70€), I think they outperform many gaming headphone brands like Razer, etc. For gaming, movies, and daily music use, they are totally VFM. The whole construction is plastic, very lightweight but they feel sturdy. The pads are of good quality and seem to have durability over time

    Quite good headphones for their price and a satisfactory microphone with slight voice distortion. Just to mention some negatives that are not immediately apparent:

    1. The headphones are not exactly over-ear but something in between with on-ear, I would say, due to the small oval space for the ear (height 5.5cm, width 3cm). If someone has smaller ears, then it's fine, but the shape and the internal size of the pads are not suitable for everyone. It means that they may need occasional breaks or slight movement of the ear to the right or left.
    2. The padding on the headband is quite small (maybe 0.5cm) and may cause slight discomfort after some time.
    3. Although the headphones are closed-back, the passive sound isolation from the environment is very minimal. Practically, you can hear most things around you. Of course, someone may prefer this.

    Good headphones with good sound, the microphone is great. After a few months of use, I haven't seen any damage to the leather or the headphones in general. It would be nice if there was also a splitter for towers in the packaging. The cable is detachable and locks with a half turn on the headphones so it doesn't come off if pulled. Overall, they are good for their price and I don't regret the purchase. The only drawback is that after a while, the headband hurts the top of my head, but I don't expect anything better at this price.
