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, Bose QuietComfort Ultra are one of those. With a detachable cable, JBL Live 660NC too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
IP ratings refer to the level of protection offered by an electrical enclosure, against solids and liquids. The letters 'IP' are followed by two numerals The first number of the IP rating refers to protection against solids say dust, while the second refers to protection against liquid.
Having a value of IPX4, the Bose QuietComfort Ultra's rating is read as, the first number of X denotes that no data available to specify a protection rating, and the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.
Twisted headphone cables can be a great source of annoyance and inconvenience, Bose QuietComfort Ultra'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
completely damaging your headphones. JBL Live 660NC too have a cable designed to help prevent tangles.
Over-ear headphones have larger earpads that fit around your entire ear Bose QuietComfort Ultra 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. JBL Live 660NC with this design offer potential for maximum bass and loudness levels.
Bose QuietComfort Ultra 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 JBL Live 660NC and Bose QuietComfort Ultra 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.
Bose QuietComfort Ultra 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 Live 660NC 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 environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out.
The Bose QuietComfort Ultra 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 Live 660NC 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 component reproduces low audible frequencies and if it makes any changes to the signal while at it.
Bose QuietComfort Ultra's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass. JBL Live 660NC's lowest frequency is at 16Hz, this implies that
Bose QuietComfort Ultra got a juicier bass than the JBL Live 660NC
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 while at it. Bose QuietComfort Ultra's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
JBL Live 660NC's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Bose QuietComfort Ultra driver unit is 35mm in diameter, bigger drivers are more powerful and can produce better bass. JBL Live 660NC driver unit is 40mm in diameter,
making them have a larger driver unit than that of Bose QuietComfort Ultra by 5mm
, 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 yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound. Defined as the device's resistance to the electromagnetic current, as electricity flows through a wire, it faces electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms.
Bose QuietComfort Ultra's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power. JBL Live 660NC's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
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. Bose QuietComfort Ultra's battery life is 24 hours
JBL Live 660NC's battery life is 50 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.
