Has Active Noise Cancellation (Anc)
Bose QuietComfort 45
✓
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 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.
Bose QuietComfort 45 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
Bose QuietComfort 45
✓
Master & Dynamic MW65 ✓
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 Bose QuietComfort 45 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
Bose QuietComfort 45
✗
Master & Dynamic MW65 20Hz
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. Master & Dynamic MW65's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
Bose QuietComfort 45
✗
Master & Dynamic MW65 20000Hz
High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it makes any changes to the signal on the way through. Master & Dynamic MW65's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Driver Unit Size
Bose QuietComfort 45
40mm
Master & Dynamic MW65 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Bose QuietComfort 45 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.
Impedance
Bose QuietComfort 45
✗
Master & Dynamic MW65 32Ohms
Impedance is 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 conductor is measured in ohms. Master & Dynamic MW65's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Has A Neodymium Magnet
Bose QuietComfort 45
✗
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 Master & Dynamic MW65 have this type of magnet.
