Has Active Noise Cancellation (Anc)

Sennheiser Momentum 4 Wireless ✓

JBL Live 660NC ✓

Active noise cancellation uses more advanced technology to actively counter noise. 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 zero resulting in a reduced level of 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.

Sennheiser Momentum 4 Wireless 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

Sennheiser Momentum 4 Wireless ✗

JBL Live 660NC ✓

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.

Lowest Frequency

Sennheiser Momentum 4 Wireless 6Hz

JBL Live 660NC 16Hz

Low-frequency response measures if and how well an audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. JBL Live 660NC's lowest frequency is at 16Hz, the lower the low-frequency response, the stronger and juicier the bass.

Sennheiser Momentum 4 Wireless's lowest frequency is at 6Hz, this means that JBL Live 660NC got a juicier bass than the Sennheiser Momentum 4 Wireless

Highest Frequency

Sennheiser Momentum 4 Wireless 22,000Hz

JBL Live 660NC 20,000Hz

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. JBL Live 660NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sennheiser Momentum 4 Wireless's highest frequency is at 22,000Hz, this means that Sennheiser Momentum 4 Wireless got a clearer and crispier treble than the JBL Live 660NC

Sound Pressure Level

Sennheiser Momentum 4 Wireless 106dB/mW

JBL Live 660NC 97dB/mW

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

Sennheiser Momentum 4 Wireless's sound pressure level measurement is 106dB/mW.

Driver Unit Size

Sennheiser Momentum 4 Wireless 42mm

JBL Live 660NC 40mm

The driver unit is the component 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.

Sennheiser Momentum 4 Wireless driver unit is 42mm in diameter, making them have a larger driver unit than that of JBL Live 660NC 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.

Impedance

Sennheiser Momentum 4 Wireless 60Ohms

JBL Live 660NC 32Ohms

Defined as the device's resistance to the electromagnetic current, when electricity flows through a wire, it faces electrical resistance that counters the flow of current. The resistance of a wire 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.

Sennheiser Momentum 4 Wireless's impedance is 60Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Has A Neodymium Magnet

Sennheiser Momentum 4 Wireless ✓

JBL Live 660NC ✗

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.
