A breakdown of the review per specifications



Sony WH 1000XM5 250g
KEF Mu7 309g

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 take in account a lower weight best because lighter devices are more comfortable to transport.

The Sony WH 1000XM5, at 250g weigh less than the KEF Mu7 with a difference -59g

Has A Detachable Cable

Sony WH 1000XM5

Detachable cables are cables that have connectors on both ends. One end goes into your headphone cups, 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, Sony WH 1000XM5 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.

Has A Tangle Free Cable

Sony WH 1000XM5

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 microfractures in the copper wires, affecting sound quality, or rendering your headphones defective.

Sony WH 1000XM5 too have a cable designed to help prevent tangles.

Cable Length

Sony WH 1000XM5 1.2meters

A long cable ensures more freedom of movement, but remember that every cable based on the conducting material used has a certain amount of parasitic resistance, inductance, and capacitance. How much depends on the length and construction. Sony WH 1000XM5 comes with a 1.2meters cable.

Has An Over-The-Ear Foam

Sony WH 1000XM5

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.

Sony WH 1000XM5 with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

Sony WH 1000XM5

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.

The Sony WH 1000XM5 also have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

Sony WH 1000XM5

Active noise cancellation uses more advanced technology to actively counter noise. 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 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.

Sony WH 1000XM5 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

Sony WH 1000XM5

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 Sony WH 1000XM5 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sony WH 1000XM5 4hz
KEF Mu7 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. KEF Mu7's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Sony WH 1000XM5's lowest frequency is at 4Hz, this means that KEF Mu7 got a juicier bass than the Sony WH 1000XM5

Highest Frequency

Sony WH 1000XM5 40,000hz
KEF Mu7 20,000hz

High frequency response measures if and how well an audio component reproduces high audible frequencies and if it makes any changes to the signal while at it. KEF Mu7's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sony WH 1000XM5's highest frequency is at 40,000Hz, this means that Sony WH 1000XM5 got a clearer and crispier treble than the KEF Mu7

Sound Pressure Level

Sony WH 1000XM5 102db/mw
KEF Mu7 96db/mw

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, KEF Mu7's measurement is 96dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Sony WH 1000XM5's sound pressure level measurement is 102dB/mW.

Driver Unit Size

Sony WH 1000XM5 30mm
KEF Mu7 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.

Sony WH 1000XM5 driver unit is 30mm in diameter, which means that they have a smaller driver unit than that of KEF Mu7 by 10mm , 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 are capable of generating louder sound, but this does not mean that they produce better sound.


Sony WH 1000XM5 48ohms
KEF Mu7 20ohms

Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. KEF Mu7's impedance is 20Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Sony WH 1000XM5's impedance is 48Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Has A Neodymium Magnet

Sony WH 1000XM5

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.

Sony WH 1000XM5 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.


Battery Life
