Has Active Noise Cancellation (Anc)
Sony WH 1000XM4
✓
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 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.
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.
Has Passive Noise Reduction
Sony WH 1000XM4
✓
Audeze Mobius ✗
Passive Noise Cancellation uses well-designed ear cups to seal out environment 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.
Lowest Frequency
Sony WH 1000XM4
4Hz
Audeze Mobius 10Hz
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 while at it. Sony WH 1000XM4's lowest frequency is at 4Hz, the lower the low-frequency response, the stronger and juicier the bass.
Audeze Mobius's lowest frequency is at 10Hz, this means that
Audeze Mobius got a juicier bass than the Sony WH 1000XM4
Highest Frequency
Sony WH 1000XM4
40000Hz
Audeze Mobius 50000Hz
High frequency response measures if and how well a particular audio device 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.
Audeze Mobius's highest frequency is at 50000Hz, this means that
Audeze Mobius got a clearer and crispier treble than the Sony WH 1000XM4
Sound Pressure Level
Sony WH 1000XM4
105dB/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 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.
Driver Unit Size
Sony WH 1000XM4
40mm
Audeze Mobius 100mm
The driver unit is the component 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.
Audeze Mobius driver unit is 100mm in diameter,
making them have a larger driver unit than that of Sony WH 1000XM4 by 60mm
, 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 deliver better sound.
Impedance
Sony WH 1000XM4
16Ohms
Audeze Mobius ✗
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a wire, 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.
Has A Neodymium Magnet
Sony WH 1000XM4
✓
Audeze Mobius ✓
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 Sony WH 1000XM4 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.
