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
15 - 25000 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
60 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
101 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.

    After much thought, research, and reviews on YouTube, etc., I decided to purchase these headphones. They have that retro design that reminds me of my youth's walkman. Their sound is very good. However, that's about it. I can't find anything else positive.
    1st: They appear to be poorly made, and you fear they will fall apart at the slightest movement. When I use them, I try to be focused, careful not to make any sudden movements and accidentally press or pull them, etc. It's extremely annoying and tiring.
    2nd: I'm very afraid of this cable. If you accidentally pull it or get it tangled somewhere, "goodbye!"
    3rd: Due to their design, they provide no sound isolation. None at all. You can hear even the birds chirping outside. While they offer great sound, you have to be in a completely quiet space to enjoy your music.
    4th: They are too expensive for what they offer. Their real cost should be around €20-€25.

    In short, look for something else in this price range.
