Has Active Noise Cancellation (Anc)
JBL Tune 750BTNC
✓
Bowers & Wilkins Px8 ✓
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes 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 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.
Bowers & Wilkins Px8 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 suits your commute or that enhances your relaxation time.
Has Passive Noise Reduction

Bowers & Wilkins Px8 ✓
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.
Both of these devices have passive noise reduction which means that also the Bowers & Wilkins Px8 isolates you from ambient noise instead of actively using technology to cancel it out.
Lowest Frequency
JBL Tune 750BTNC
20Hz
Bowers & Wilkins Px8 ✗
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. JBL Tune 750BTNC's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
JBL Tune 750BTNC
20,000Hz
Bowers & Wilkins Px8 ✗
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it makes any changes to the signal while at it. JBL Tune 750BTNC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound Pressure Level
JBL Tune 750BTNC
100dB/mW
Bowers & Wilkins Px8 ✗
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
JBL Tune 750BTNC
40mm
Bowers & Wilkins Px8 40mm
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.
Bowers & Wilkins Px8 driver unit is 40mm in diameter,
making both Bowers & Wilkins Px8, and JBL Tune 750BTNC similar in how loud their sound gets
, 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 yes, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
Impedance
JBL Tune 750BTNC
32Ohms
Bowers & Wilkins Px8 ✗
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor 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.
