Active noise cancellation uses more advanced technology to actively counter noise.
How it works, it listens to the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make 0 resulting in a reduced level of noise.
JBL Tune 670NC allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise.
Sony WH CH720N too have active noise cancellation making both devices ideal for plane rides and morning commutes. Each may work with different noise cancellation modes, pick the setting, mode, or noise cancellation type that you prefer for commute or that enhances your relaxation time. 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.
JBL Tune 670NC's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass. Sony WH CH720N's lowest frequency is at 20Hz, this means that
both devices produce equal bass
High frequency response measures if and how well an audio device reproduces high audible frequencies and if it changes to the signal on the way through. JBL Tune 670NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sony WH CH720N's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
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, JBL Tune 670NC's measurement is 98dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sony WH CH720N's sound pressure level measurement is 99dB/mW. The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. JBL Tune 670NC driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass.
Sony WH CH720N driver unit is 30mm in diameter,
which means that they have a smaller driver unit than that of JBL Tune 670NC by 2mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so it's true that, larger drivers can generate louder sound, but this does not mean that they produce better sound. Defined as the device's resistance to the electromagnetic current, as electricity flows through a wire, it experiences electrical resistance that counters the flow of current.
The resistance of a conductor is measured in ohms. JBL Tune 670NC's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power. Sony WH CH720N's impedance is 31Ohms.
The impedance of earbuds is the electrical resistance of the driver unit present on the inside. 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.
JBL Tune 670NC's battery life is 70 hours
Sony WH CH720N's battery life is 50 hours. Each time you recharge your headphones, they get a little less listening time. The effect is barely noticeable at first.
