With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
3.can be folded
AKG K15
Koss KDE250
Foldable devices are easier to transport and take up less storage space.
4.travel bag is included
AKG K15
Koss KDE250
The device comes with its own special case or pouch, which is useful for safe transportation.
5.has an on-ear form
AKG K15

Sound quality

1.lowest frequency

20Hz

40Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
2.highest frequency

20000Hz

20000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.sound pressure level

113dB/mW

95dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
4.impedance

32 Ohms

16 Ohms

Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.

Connectivity

1.Can be used wirelessly
AKG K15
Koss KDE250
Wireless devices allow users more freedom of movement.
2.has a 3.5mm male connector
