Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud 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 0 resulting in a reduced level of noise.
Sennheiser Momentum 4 Wireless 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. 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. Sennheiser Momentum 4 Wireless's lowest frequency is at 6Hz, 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 changes to the signal on the way through. Sennheiser Momentum 4 Wireless's highest frequency is at 22,000Hz, 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, Sennheiser Momentum 4 Wireless's measurement is 106dB/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.
Sennheiser Momentum 4 Wireless driver unit is 42mm in diameter, bigger drivers are more powerful and can produce better bass. Bowers & Wilkins PX7 S2 driver unit is 40mm in diameter,
which means that they have a smaller driver unit than that of Sennheiser Momentum 4 Wireless 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 yes, larger drivers are capable of generating 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 conductor, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sennheiser Momentum 4 Wireless's impedance is 60Ohms, 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 while using less power. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sennheiser Momentum 4 Wireless have this type of magnet.
