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 prefer a lower weight better because lighter devices are more comfortable to carry.
Bowers & Wilkins Px8, at 320g are heavier than the KEF Mu7 with a difference 11g
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, Bowers & Wilkins Px8 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
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
completely damaging your headphones.
Bowers & Wilkins Px8 too have a cable designed to help prevent tangles.
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. Bowers & Wilkins Px8 comes with a 1.2meters cable.
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.
Bowers & Wilkins Px8 with this design offer potential for maximum bass and loudness levels.
KEF Mu7 have stereo speakers, what this means is that KEF Mu7's speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.
Both Bowers & Wilkins Px8 and KEF Mu7 have stereo speakers
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern of incoming noise 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 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.
Bowers & Wilkins Px8 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.
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 Bowers & Wilkins Px8 isolates you from ambient noise instead of actively using technology to cancel it out.
The driver unit is the component 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.
Bowers & Wilkins Px8 driver unit is 40mm in diameter, making both devices 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
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
Bowers & Wilkins Px8's battery life is 30 hours. Each time you recharge your headphones, they get a little less listening time. The effect is barely noticeable at first. But over a few years, you may find that your device, no longer plays for long like it used to.
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.
Bowers & Wilkins Px8 too have a battery level indicator, charging indicators allow you to determine the charging state of your headphones, whether fully charged, or the battery is running low.
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.
The Bowers & Wilkins Px8 too have a rechargeable battery.
KEF Mu7 can be used wirelessly, wireless devices allow users more freedom of movement.
The Bowers & Wilkins Px8 also can be used wirelessly
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
Bowers & Wilkins Px8 has a Bluetooth version of v5.2. Newer versions provide faster data transfers.
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.
Bowers & Wilkins Px8 too have USB TYPE-C
Bowers & Wilkins Px8 support APTX Adaptive, an audio codec for Bluetooth devices that are developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.
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).
Bowers & Wilkins Px8 support APTX HD too.
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.
Bowers & Wilkins Px8 support APTX
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.
The Bowers & Wilkins Px8 support AAC as well. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same 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.
Bowers & Wilkins Px8 too have this kind of connector
Bowers & Wilkins Px8 have only 2 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.
The Bowers & Wilkins Px8 too use a noise-canceling type of microphone.
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.
The Bowers & Wilkins Px8 support ambient sound mode as well allowing you to hear the ambient sound even while wearing them.
Bowers & Wilkins Px8 support in/on-ear detection, the sensors in the device can detect when they are removed from your ears so that the music is paused, saving battery life and improving your listening experience while at it.
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.
There is a control panel on the Bowers & Wilkins Px8 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.
Bowers & Wilkins Px8 can be used as a headset. since they have a built-in microphone
Carrying headphones without a case, or putting them in bags without a casing can easily put them at risk of getting damaged. The Bowers & Wilkins Px8 come with their own special case or pouch, which is useful for safe transportation.
