Has Active Noise Cancellation (Anc)
Sennheiser Momentum 4 Wireless
✓
Audeze Mobius ✗
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 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.
Lowest Frequency
Sennheiser Momentum 4 Wireless
6Hz
Audeze Mobius 10Hz
Low-frequency response measures if and how well an 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.
Audeze Mobius's lowest frequency is at 10Hz, this implies that
Audeze Mobius got a juicier bass than the Sennheiser Momentum 4 Wireless
Highest Frequency
Sennheiser Momentum 4 Wireless
22000Hz
Audeze Mobius 50000Hz
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. Sennheiser Momentum 4 Wireless's highest frequency is at 22000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Audeze Mobius's highest frequency is at 50000Hz, this means that
Audeze Mobius got a clearer and crispier treble than the Sennheiser Momentum 4 Wireless
Sound Pressure Level
Sennheiser Momentum 4 Wireless
106dB/mW
Audeze Mobius ✗
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.
Driver Unit Size
Sennheiser Momentum 4 Wireless
42mm
Audeze Mobius 100mm
The driver unit is the component 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.
Audeze Mobius driver unit is 100mm in diameter,
making them have a larger driver unit than that of Sennheiser Momentum 4 Wireless by 58mm
, 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 yeah, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
Sennheiser Momentum 4 Wireless
60Ohms
Audeze Mobius ✗
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a wire, 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.
Has A Neodymium Magnet
Sennheiser Momentum 4 Wireless
✓
Audeze Mobius ✓
Neodymium magnets if 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.
Audeze Mobius 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.
