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 - 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.

    Very good sound, loud! Its battery is off in 2 years, but it has a cable so you can still listen with a cable!

    I found them in front of me for 10€ per hour, while my own "greeted" me, I didn't think about it! It has buttons for volume, song change, on/off, and most importantly: it accepts memory cards!!! Excellent sound both in song playback and in calls. I would say it's value for money. I have changed many headphones over time, from cheap ones for 3€ to full branded ones, and they didn't last.. These here are the best.

    After listening for years at full volume with flea headphones, these really take the sound intensity to another level that I had never heard before. It's like having a wireless mini speaker when you turn them up to the max, both from the phone and from the headphones.

    After more than two weeks of use, I can say that the sound is quite flat but satisfactory for what you pay, and it's fine for the ears after two hours. I haven't tried it for longer. If you want to listen at full volume, only through Bluetooth.
