Lowest Frequency
JLab Audio Play
20Hz
Adidas RPT 02 Sol 20Hz
Low-frequency response measures if and how well a particular audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. JLab Audio Play's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Adidas RPT 02 Sol's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Highest Frequency
JLab Audio Play
20000Hz
Adidas RPT 02 Sol 20000Hz
High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal on the way through. JLab Audio Play's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Adidas RPT 02 Sol's highest frequency is at 20000Hz, this means that
both devices produce equal treble
Sound Pressure Level
JLab Audio Play
110dB/mW
Adidas RPT 02 Sol 105dB/mW
Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, JLab Audio Play's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Adidas RPT 02 Sol's sound pressure level measurement is 105dB/mW.
Driver Unit Size
JLab Audio Play
40mm
Adidas RPT 02 Sol 45mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. JLab Audio Play driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Adidas RPT 02 Sol driver unit is 45mm in diameter,
making them have a larger driver unit than that of JLab Audio Play by 5mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
JLab Audio Play
32Ohms
Adidas RPT 02 Sol 32Ohms
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a wire, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. JLab Audio Play's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Adidas RPT 02 Sol's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
Has A Neodymium Magnet
JLab Audio Play
✓
Adidas RPT 02 Sol ✗
Neodymium magnets when used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The JLab Audio Play have this type of magnet.
