Price comparison

Design

1.has stereo speakers
RHA T20
Sony XBA-4
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

39g

8g

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.travel bag is included
RHA T20
Sony XBA-4
The device comes with its own special case or pouch, which is useful for safe transportation.
4.has an in-ear form
RHA T20
Sony XBA-4
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.
5.cable length

1.35m

1.2m

A long cable ensures more freedom of movement.
6.has an L-shaped plug
RHA T20
Sony XBA-4
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.lowest frequency

16Hz

3Hz

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

40000Hz

28000Hz

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
RHA T20
Sony XBA-4
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

90dB/mW

108dB/mW

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

16 Ohms

8 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.
6.has a neodymium magnet
RHA T20
Sony XBA-4
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

Connectivity

1.has a 3.5mm male connector
RHA T20
Sony XBA-4
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
