Type
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.
Frequency Response
20 - 22000 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
90 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.

No

Foldable Drivers

Folding ear cups help reduce the volume of headphones, making them easier to transport.

Headphones with folding ear cups often come with a carrying case.
Rotating Capsules
No

Rotating Capsules

Rotating ear cups allow headphones to have a flat shape, making them easier to transport (e.g. in a suitcase).

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.

    They have good construction quality and fold to be stored. They do not have a detachable cable as stated in the specifications, but instead they have collapsible ear cups contrary to the description. They are small for the ears of elementary school children (the smallest is in the 2nd grade) and after one to one and a half hours of use, they complain that their ears hurt from the ear cups.
