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.
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
