Has Active Noise Cancellation (Anc)

KEF Mu7 ✓

Bose QuietComfort 45 ✓

Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise 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 zero hence "diluting" the noise.

KEF Mu7 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.

Bose QuietComfort 45 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

KEF Mu7 ✓

Bose QuietComfort 45 ✓

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 KEF Mu7 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 Bose QuietComfort 45 isolates you from ambient noise instead of actively using technology to cancel it out.

Driver Unit Size

KEF Mu7 40mm

Bose QuietComfort 45 40mm

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. KEF Mu7 driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.

Bose QuietComfort 45 driver unit is 40mm in diameter, making both Bose QuietComfort 45, and KEF Mu7 similar in how loud their sound gets , 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 can generate louder sound, but this does not mean that they produce better sound.

Has A Neodymium Magnet

KEF Mu7 ✓

Bose QuietComfort 45 ✗

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 KEF Mu7 have this type of magnet.
