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, JBL Live 670NC are one of those. With a detachable cable, Bose QuietComfort Headphones too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
JBL Live 670NC 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, JBL Live 670NC'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. Bose QuietComfort Headphones too have a cable designed to help prevent tangles. By sweat resistance we mean that the wireless earbuds are protected in the presence of low-pressure water jets at any angle, this is determined by the IP Rating of the earbuds.

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. JBL Live 670NC comes with a 0.2meters cable.
On-ear headphones have smaller earpads that sit on top of your ears, this JBL Live 670NC comfortably rests on top of your outer ears. As it doesn't block out everything from the outside world, it's preferred in places like office environments and recommended for outdoor activities. JBL Live 670NC have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, this creates a richer sound and a better listening experience.
Both Bose QuietComfort Headphones and JBL Live 670NC have stereo speakers
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 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.
JBL Live 670NC 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. Bose QuietComfort Headphones 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 JBL Live 670NC 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 Bose QuietComfort Headphones isolates you from ambient noise instead of actively using technology to cancel it out. Low-frequency response measures if and how well a particular audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through. JBL Live 670NC's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Bose QuietComfort Headphones's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it makes any changes to the signal on the way through. JBL Live 670NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble. Bose QuietComfort Headphones's highest frequency is at 20,000Hz, this implies that
both devices produce equal 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 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 Live 670NC's measurement is 98dB/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.
JBL Live 670NC driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass. Bose QuietComfort Headphones 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they produce better sound.
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. JBL Live 670NC's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
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. JBL Live 670NC's battery life is 65 hours
Bose QuietComfort Headphones's battery life is 24 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 3 hours to fully charge the JBL Live 670NC'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. Bose QuietComfort Headphones takes 2.5 hours to fully charge the battery
JBL Live 670NC 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. Bose QuietComfort Headphones 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.
