Has Active Noise Cancellation (Anc)
Sony WH 1000XM4
✓
Master & Dynamic MW65 ✓
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes 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.
Master & Dynamic MW65 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.
Has Passive Noise Reduction

Master & Dynamic MW65 ✓
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.
Both of these devices have passive noise reduction which means that also the Master & Dynamic MW65 isolates you from ambient noise instead of actively using technology to cancel it out.
Lowest Frequency
Sony WH 1000XM4
4Hz
Master & Dynamic MW65 20Hz
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. Sony WH 1000XM4's lowest frequency is at 4Hz, the lower the low-frequency response, the stronger and juicier the bass.
Master & Dynamic MW65's lowest frequency is at 20Hz, this means that
Master & Dynamic MW65 got a juicier bass than the Sony WH 1000XM4
Highest Frequency
Sony WH 1000XM4
40000Hz
Master & Dynamic MW65 20000Hz
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it 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.
Master & Dynamic MW65's highest frequency is at 20000Hz, this means that
Sony WH 1000XM4 got a clearer and crispier treble than the Master & Dynamic MW65
Sound Pressure Level
Sony WH 1000XM4
105dB/mW
Master & Dynamic MW65 ✗
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, 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
Master & Dynamic MW65 40mm
The driver unit is basically a mini speaker 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.
Master & Dynamic MW65 driver unit is 40mm in diameter,
making both devices similar in how loud their sound gets
, 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
Impedance
Sony WH 1000XM4
16Ohms
Master & Dynamic MW65 32Ohms
Defined as 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 wire 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.
Master & Dynamic MW65's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
Has A Neodymium Magnet
Sony WH 1000XM4
✓
Master & Dynamic MW65 ✓
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.
Master & Dynamic MW65 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.
