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 a way of getting 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, Sennheiser HD 350BT's measurement is 108dB/mW.
Devices with a higher sound pressure level are generally louder when supplied with any given audio source. JBL Tune 520BT's sound pressure level measurement is 103dB/mW. The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone.
Sennheiser HD 350BT driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass. JBL Tune 520BT driver unit is 30mm in diameter,
which means that they have a smaller driver unit than that of Sennheiser HD 350BT by 2mm
, 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 are capable of generating louder sound, but this does not mean that they produce better sound.
Impedance is the device's resistance to the electromagnetic current, when electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sennheiser HD 350BT's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
JBL Tune 520BT's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside. Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output while using less power.
They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sennheiser HD 350BT have this type of magnet. If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time.
The device's battery life is given by the manufacturer, with longer battery life, you get to use it for longer and have to charge the device less often. Sennheiser HD 350BT's battery life is 30 hours
JBL Tune 520BT's battery life is 57 hours. Each time you recharge your headphones, they get a little less listening time.
