On Ear

Type

On Ear

Headphones with smaller ear cups compared to over-ear headphones, which sit on the ears.

They are more portable due to their smaller size, but offer less comfort and isolation from external noise.

Generally, over-ear headphones, thanks to their larger speakers, can offer better sound quality and deep bass compared to on-ear headphones of similar quality.
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.

Noise Cancellation

The method of reducing external noise that the headphones have.

Active Noise Cancellation (ANC): Uses technology to detect and neutralize external noises, offering clearer sound.

Passive Noise Cancellation: The shape and materials of the headphones naturally reduce external noises, improving the listening experience.
