Design

1.has stereo speakers
Etymotic ER 4PT
RHA T20

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

RHA T20

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

4.has an in-ear form
Etymotic ER 4PT
RHA T20

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.has an L-shaped plug
Etymotic ER 4PT
RHA T20

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.

6.has a straight plug

RHA T20

A straight plug is better when the jack is on the top or bottom of your player.

Sound quality

1.lowest frequency

20Hz

16Hz

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

2.highest frequency

16000Hz

40000Hz

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

3.sound pressure level

102dB/mW

90dB/mW

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

Best

AKG K553 Pro

144dB/mW

4.has sound isolation/passive noise reduction
Etymotic ER 4PT
RHA T20

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

5.has a neodymium magnet
Etymotic ER 4PT
RHA T20

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

27 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.

Best

Flips Solo 2 Social

4 Ohms

Connectivity

1.has a 3.5mm male connector
