Has Active Noise Cancellation (Anc)
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 zero 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.
JBL Tour ONE 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
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 JBL Tour ONE isolates you from ambient noise instead of actively using technology to cancel it out.
Lowest Frequency
JBL Tour ONE
10Hz
KEF Mu7 ✗
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 on the way through. JBL Tour ONE's lowest frequency is at 10Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
JBL Tour ONE
40000Hz
KEF Mu7 ✗
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. JBL Tour ONE's highest frequency is at 40000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound Pressure Level
JBL Tour ONE
95dB/mW
KEF Mu7 ✗
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, JBL Tour ONE's measurement is 95dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Driver Unit Size
JBL Tour ONE
40mm
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.
JBL Tour ONE 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 yes, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
Impedance
JBL Tour ONE
32Ohms
KEF Mu7 ✗
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 wire is measured in ohms. JBL Tour ONE's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Has A Neodymium Magnet
Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output while using less power. 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.
