Price comparison

Design

1.has stereo speakers
Audio-Technica ATH-CKS77BK
SoundMagic P21S
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.weight

7g

115g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
3.can be folded
Audio-Technica ATH-CKS77BK
SoundMagic P21S
Foldable devices are easier to transport and take up less storage space.
4.travel bag is included
Audio-Technica ATH-CKS77BK
SoundMagic P21S
The device comes with its own special case or pouch, which is useful for safe transportation.
5.has an in-ear form
Audio-Technica ATH-CKS77BK
SoundMagic P21S
The in-ear device is ultracompact and lightweight, with little or no interference with earrings, spectacles, hats, or hairstyles. It is inserted in the ear canal itself and blocks out a lot of environmental noise. It has stronger bass tones and is unlikely to fall out of the ear.
6.has a tangle free cable
Audio-Technica ATH-CKS77BK
SoundMagic P21S
The cable is designed to minimize tangling.

Sound quality

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

25000Hz

22000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.has passive noise reduction
Audio-Technica ATH-CKS77BK
SoundMagic P21S
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

106dB/mW

103dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
5.has a neodymium magnet
Audio-Technica ATH-CKS77BK
SoundMagic P21S
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.
6.impedance

14 Ohms

32 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
Audio-Technica ATH-CKS77BK
SoundMagic P21S
Wireless devices allow users more freedom of movement.
2.has a 3.5mm male connector
Audio-Technica ATH-CKS77BK
SoundMagic P21S
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
