The JBL Live 660NC have a weight of 265g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We take in account a lower weight better for the reason that lighter devices are more comfortable to carry. Detachable cables are cables that have connectors on both ends.
One end goes into your headphone cups, 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 660NC are one of those. JBL Live 660NC 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 660NC'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.
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 660NC comes with a 1.2meters cable.
Over-ear headphones have larger earpads that fit around your entire ear JBL Live 660NC 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 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.
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 hence "diluting" the noise.
JBL Live 660NC 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. 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 660NC sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out. Low-frequency response measures if and how well an audio component reproduces low audible frequencies and if it makes any changes to the signal on the way through. JBL Live 660NC's lowest frequency is at 16Hz, the lower the low-frequency response, the stronger and juicier the bass.
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 Live 660NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the 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 660NC's measurement is 97dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source. The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone.
JBL Live 660NC driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass. Impedance is the device's resistance to the electromagnetic current, when electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms.
JBL Live 660NC'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 660NC's battery life is 50 hours
It takes 2 hours to fully charge the JBL Live 660NC'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. JBL Live 660NC 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. 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. JBL Live 660NC's battery can be recharged and used over again.
JBL Live 660NC can be used wirelessly, wireless devices allow you more freedom of movement not restricted by a cable. Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. JBL Live 660NC has a v5
JBL Live 660NC 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. JBL Live 660NC 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. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances. The JBL Live 660NC can connect at a 10meters distance via Bluetooth or infrared to another device.
JBL Live 660NC 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. JBL Live 660NC 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. JBL Live 660NC 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.
JBL Live 660NC support multipoint, which allows you to link to more Bluetooth devices and switch between them. For example, you can easily switch calls from one device to another without having to manually disconnect and reconnect. There is a control panel on the JBL Live 660NC 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.
JBL Live 660NC 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. The period of time that warrant free repair and adjustment services in case of a malfunction occurring under normal use that has followed instruction manuals. When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction.
JBL Live 660NC have a warranty period of 1 years
Carrying headphones without a case, or putting them in bags without a casing can easily put them at risk of getting damaged. The JBL Live 660NC come with their own special case or pouch, which is useful for safe transportation.
