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 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 0 hence "diluting" the 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.
Bang & Olufsen Beoplay Portal 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 you prefer for 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 Bang & Olufsen Beoplay Portal sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
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 on the way through.

High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal on the way through. Sennheiser Momentum 4 Wireless's highest frequency is at 22000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Bang & Olufsen Beoplay Portal's highest frequency is at 22000Hz, this implies that both devices produce equal 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 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, 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.
Bang & Olufsen Beoplay Portal's sound pressure level measurement is 95dB/mW.
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.
Bang & Olufsen Beoplay Portal driver unit is 40mm in diameter, which means that they have a smaller driver unit than that of Sennheiser Momentum 4 Wireless by 2mm , 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 are capable of generating louder sound, but this does not mean that they produce better sound.
A speaker driver is an individual transducer that converts electrical energy to sound waves. Drivers come in different sizes and modes, but generally, you'll find three types: tweeter driver, which handles the high-frequency treble range (above 2,000 Hz), and midrange driver: which handles the midrange frequencies (200 Hz to 2,000 Hz). Woofer driver: which handles the low-frequency bass range (below 200 Hz).
Based on the frequencies they handle more drivers may result in better sound quality, Bang & Olufsen Beoplay Portal have 2 only.
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. Sennheiser Momentum 4 Wireless's impedance is 60Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Bang & Olufsen Beoplay Portal's impedance is 24Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
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 Sennheiser Momentum 4 Wireless have this type of magnet.
Bang & Olufsen Beoplay Portal have it too, devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. It is also known that they have more bass and clear high notes.
