Lowest Frequency
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 on the way through. JLab Audio Play's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it makes any 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.
Sound Pressure Level
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.
Driver Unit Size
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.
Impedance
Defined as 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.
Has A Neodymium Magnet
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.
