Has Active Noise Cancellation (Anc)

JBL Live 660NC ✓

Bowers & Wilkins PX7 S2 ✓

Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud 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 Live 660NC 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 PX7 S2 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

JBL Live 660NC ✓

Bowers & Wilkins PX7 S2 ✓

Passive Noise Cancellation uses well-designed ear cups to seal out unwanted noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The JBL Live 660NC 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 PX7 S2 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

JBL Live 660NC 16Hz

Bowers & Wilkins PX7 S2 ✗

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 Live 660NC's lowest frequency is at 16Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

JBL Live 660NC 20,000Hz

Bowers & Wilkins PX7 S2 ✗

High frequency response measures if and how well an audio device reproduces high audible frequencies and if it makes any changes to the signal while at it. JBL Live 660NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sound Pressure Level

JBL Live 660NC 97dB/mW

Bowers & Wilkins PX7 S2 ✗

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, JBL Live 660NC's measurement is 97dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

JBL Live 660NC 40mm

Bowers & Wilkins PX7 S2 40mm

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. JBL Live 660NC driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.

Bowers & Wilkins PX7 S2 driver unit is 40mm in diameter, making both devices 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 are capable of generating louder sound, but this does not mean that they produce better sound.

Impedance

JBL Live 660NC 32Ohms

Bowers & Wilkins PX7 S2 ✗

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 Live 660NC's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
