Overall Score 6.4 Represents average audio ecosystem compatibility score.
The 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 for the reason that lighter devices are more comfortable to move with.
Detachable cables are cables that have connectors on both ends. One end goes into your headphone earpieces, while the other end is inserted into a source device. Some new headphones, and not just the expensive ones, are coming with detachable cables, KEF Mu7 are one of those.
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.
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.
KEF Mu7 have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. 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.
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.
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 KEF Mu7 sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Low-frequency response measures if and how well a particular 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.
High frequency response measures if and how well an audio device reproduces high audible frequencies and if it changes to the signal on the way through. KEF Mu7's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
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, KEF Mu7's measurement is 96dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
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.
Defined as the device's resistance to the electromagnetic current, when electricity flows through a wire, it experiences 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.
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.
If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time. The device's battery life is given by the manufacturer, with longer battery life, you get to use it for longer and have to charge the device less often. KEF Mu7's battery life is 40 hours
It takes 2 hours to fully charge the KEF Mu7's battery. It is recommended to fully charge the battery before using the headphones for the first time or when they have been unused for extended periods.
KEF Mu7 have a battery level indicator, an indicator shows you when the device has a low battery. The battery indicator lights show the charging status of your headphones.
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. KEF Mu7's battery power is 100mAh, more battery power can be an indication of longer battery life.
A rechargeable battery is a type of electrical battery that can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. KEF Mu7's battery can be recharged and used over again.
KEF Mu7 can be used wirelessly, wireless devices allow users more freedom of movement.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. KEF Mu7 has a v5.1
KEF Mu7 support USB TYPE-C, an industry-standard connector for transmitting both data and power on a single cable. The USB-C plug is now part and parcel of most current laptops, phones, and tablets, it features reversible plug orientation and cable direction.
The KEF Mu7 support APTX HD, an audio codec for Bluetooth devices that are developed by Qualcomm. It supports high-quality 24-bit audio (at a bit rate of 576kbps).
KEF Mu7 support APTX, a codec used for transmitting audio wirelessly with Bluetooth. It is developed by Qualcomm and supports 16-bit audio at a bit rate of 384kbps.
KEF Mu7 support AAC, a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances. The KEF Mu7 can connect at a 10meters distance via Bluetooth or infrared to another device.
Being an industry standard audio plug, a standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards. This means that it is commonly used in stereo headphones to your phone or connecting your phone to an external amplifier, sound bars, your car radio, etc. KEF Mu7 has this connector giving it a wider range of connectivity with most of the sound devices out there. All plugs have at least a tip and sleeve with the number of rings that stand as a differentiating factor.
KEF Mu7 have only 4 microphones, more microphones result in better sound quality and enable the device to filter out background noise.
KEF Mu7 use a noise-canceling type of microphone, these microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.
KEF Mu7 support ambient sound mode, which uses microphones to pass through ambient noises so that they can still be heard. It’s useful when you want to listen to music but also be aware of what’s happening around you, for example when you’re having a jog but would still want to be able to hear traffic.
KEF Mu7 have a mute function, they have an option to mute/unmute a conversation directly from the device. The mute function means that you unilaterally turn off the microphone, but you can still hear the other party's voice.
KEF Mu7 support multipoint, which allows you to link to more Bluetooth devices and switch between them. For example, you can easily switch calls from one device to another without having to manually disconnect and reconnect.
There is a control panel on the KEF Mu7 body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.
KEF Mu7 can be used as a headset. A headset is one headphone or pair with a built-in microphone. Headsets can be used for apps that require communication i.e. Zoom, Google Meet, Skype, games with voice chat, mobile phones, etc.
Carrying headphones without a case, or putting them in bags without a casing can easily put them at risk of getting damaged. The KEF Mu7 come with their own special case or pouch, which is useful for safe transportation.
