A breakdown of the review per specifications

Design

Weight

KEF Mu7 309g
Shure Aonic 40 311g

KEF Mu7 have a weight of 309g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We consider a lower weight best because lighter devices are more comfortable to move with.

The Shure Aonic 40, at 311g are heavier than the KEF Mu7 by 2g

Has A Detachable Cable

KEF Mu7
Shure Aonic 40

Detachable cables are cables that have connectors on both ends. One end goes into your headphone earpieces, while the other end is inserted into an audio source. Some new headphones, and not just the expensive ones, are coming with detachable cables, KEF Mu7 are one of those.

With a detachable cable, Shure Aonic 40 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.

Can Be Folded

KEF Mu7
Shure Aonic 40

Shure Aonic 40 are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.

Has A Tangle Free Cable

KEF Mu7
Shure Aonic 40

Twisted headphone cables can be a great source of annoyance and inconvenience, KEF Mu7's cable is designed to minimize tangling. Constant twisting of the cables can also lead to bends in the copper wires, affecting sound quality, or rendering your headphones defective.

Shure Aonic 40 too have a cable designed to help prevent tangles.

Has An Over-The-Ear Foam

KEF Mu7
Shure Aonic 40

Over-ear headphones have larger earpads that fit around your entire ear KEF Mu7 have a comfortable full-size form with earcups that fully enclose your ears. This design is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors.

Shure Aonic 40 with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

KEF Mu7
Shure Aonic 40

KEF Mu7 have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.

Both Shure Aonic 40 and KEF Mu7 have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

KEF Mu7
Shure Aonic 40

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 zero resulting in a reduced level of 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.

Shure Aonic 40 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 suits your commute or that enhances your relaxation time.

Has Passive Noise Reduction

KEF Mu7
Shure Aonic 40

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 Shure Aonic 40 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

KEF Mu7
Shure Aonic 40 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 while at it. Shure Aonic 40's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

KEF Mu7
Shure Aonic 40 20000Hz

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. Shure Aonic 40's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Driver Unit Size

KEF Mu7 40mm
Shure Aonic 40 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.

Shure Aonic 40 driver unit is 40mm in diameter, making both Shure Aonic 40, and KEF Mu7 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.

Has A Neodymium Magnet

KEF Mu7
Shure Aonic 40

Neodymium magnets when 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 KEF Mu7 have this type of magnet.

Power

Battery Life

KEF Mu7 40hours
Shure Aonic 40 25hours
