Has Active Noise Cancellation (Anc)
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and then inverts the soundwaves 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 zero hence "diluting" the noise.
JBL Tune 750BTNC 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.
Has Passive Noise Reduction
Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out.
The JBL Tune 750BTNC sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Lowest Frequency
Low-frequency response measures if and how well a particular audio device reproduces low audible frequencies and if it makes any changes to the signal while at it. JBL Tune 750BTNC'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 a particular audio device reproduces high audible frequencies and if it makes any changes to the signal while at it. JBL Tune 750BTNC's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound Pressure Level
JBL Tune 750BTNC
100dB/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, JBL Tune 750BTNC's measurement is 100dB/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 basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. JBL Tune 750BTNC driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Impedance
Impedance is the device's resistance to the electromagnetic current, when electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. JBL Tune 750BTNC's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
