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, 1More SonoFlow too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
1More SonoFlow are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.
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.
1More SonoFlow too have a cable designed to help prevent tangles.
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.
1More SonoFlow with this design offer potential for maximum bass and loudness levels.
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 1More SonoFlow also have stereo speakers
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 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.
1More SonoFlow 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.
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.
Both of these devices have passive noise reduction which means that also the 1More SonoFlow isolates you from ambient noise instead of actively using technology to cancel it out.
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.
1More SonoFlow driver unit is 40mm in diameter, making both devices 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.
Impedance is the device's resistance to the electromagnetic current, when electricity flows through a wire, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. 1More SonoFlow's impedance is 32Ohms, 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
1More SonoFlow's battery life is 70 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.
1More SonoFlow takes 1.3 hours to fully charge the battery
KEF Mu7 have a battery level indicator, an indicator shows you when the device has a low battery. The battery indicator lights indicate the charging status of your headphones.
1More SonoFlow 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.
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. 1More SonoFlow's battery power is 720mAh, 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.
The 1More SonoFlow too have a rechargeable battery.
KEF Mu7 can be used wirelessly, wireless devices allow users more freedom of movement.
The 1More SonoFlow also can be used wirelessly

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 1More SonoFlow 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.
The 1More SonoFlow can connect at a 10meters distance via Bluetooth
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.
1More SonoFlow too have this kind of connector
1More SonoFlow have only 5 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 1More SonoFlow 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 1More SonoFlow support ambient sound mode as well allowing you to hear the ambient sound even while wearing them.
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.
The 1More SonoFlow too have a mute function.
