Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes 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 resulting in a reduced level of noise.
Sony WH 1000XM4 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.
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 Sony WH 1000XM4 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.
Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal while at it. Sony WH 1000XM4's lowest frequency is at 4Hz, the lower the low-frequency response, the stronger and juicier the bass.
High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it makes any changes to the signal while at it. Sony WH 1000XM4's highest frequency is at 40000Hz, the higher the high-frequency response, the clearer and crispier the 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, Sony WH 1000XM4's measurement is 105dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sony WH 1000XM4 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 , 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 it's true that, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sony WH 1000XM4's impedance is 16Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Neodymium magnets when used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sony WH 1000XM4 have this type of magnet.
