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
20 - 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
32 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
105 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
40 mm

Driver Diameter

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