Top specs and features

Design

1.has stereo speakers
Koss KDE250
Sony MDR-ZX770BN

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

2.has a detachable cable
Koss KDE250
Sony MDR-ZX770BN

With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.

3.has an over-the-ear form
Koss KDE250
Sony MDR-ZX770BN

Comfortable full-size form with earcups that fully enclose your ears. This model is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors. It offers potential for maximum bass and loudness levels.

4.has included ear pads
Koss KDE250
Sony MDR-ZX770BN

Allows you to change ear pads without buying new ones.

5.travel bag is included
Koss KDE250
Sony MDR-ZX770BN

The device comes with its own special case or pouch, which is useful for safe transportation.

6.has an L-shaped plug
Koss KDE250
Sony MDR-ZX770BN

An L-shaped plug is better if the jack is on the left or right side of the device, so that the cable isn't bent, and is less likely to break when the device is in your pocket.

Sound quality

1.highest frequency

20000Hz

22000Hz

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

Best

Sony MDR-Z1R

120000Hz

2.lowest frequency

40Hz

8Hz

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

Best

Sony MH1CBLK

1Hz

3.has sound isolation/passive noise reduction
Koss KDE250
Sony MDR-ZX770BN

The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.

4.sound pressure level

95dB/mW

98dB/mW

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

Best

AKG K553 Pro

144dB/mW

5.impedance

16 Ohms

23 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.

Best

Flips Solo 2 Social

4 Ohms

6.has a neodymium magnet
Koss KDE250
Sony MDR-ZX770BN

Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

Power

1.has a rechargeable battery

Sony MDR-ZX770BN

The battery can be recharged and used over again.

Connectivity

1.Can be used wirelessly
Koss KDE250
