The JBL Tune 720BT have a weight of 220g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We prefer a lower weight best for the reason that lighter devices are more comfortable to carry. Bose QuietComfort 45, at 240g
are heavier than the JBL Tune 720BT by 20g
Detachable cables are cables that have connectors on both ends.
One end goes into your headphone cups, while the other end is inserted into an audio source. Some new headphones, and not just the expensive ones, are coming with detachable cables, JBL Tune 720BT are one of those. With a detachable cable, Bose QuietComfort 45 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
Twisted headphone cables can be a great source of annoyance and inconvenience, JBL Tune 720BT'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 45 too have a cable designed to help prevent tangles.
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 Tune 720BT comes with a 1.2meters cable.
Over-ear headphones have larger earpads that fit around your entire ear JBL Tune 720BT 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. Bose QuietComfort 45 with this design offer potential for maximum bass and loudness levels.
JBL Tune 720BT 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 45 and JBL Tune 720BT have stereo speakers
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 Tune 720BT 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 45 isolates you from ambient noise instead of actively using technology to cancel it out. Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal while at it.
JBL Tune 720BT's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass. High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal while at it. JBL Tune 720BT'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 a way of getting 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 Tune 720BT's measurement is 103dB/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 Tune 720BT driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass. Bose QuietComfort 45 driver unit is 40mm in diameter,
making both Bose QuietComfort 45, and JBL Tune 720BT 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 yeah, 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 faces electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms.
JBL Tune 720BT'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 Tune 720BT's battery life is 76 hours
Bose QuietComfort 45'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 2 hours to fully charge the JBL Tune 720BT'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 Tune 720BT 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. Battery power, or battery capacity, represents the amount of electrical energy that a battery can store.
JBL Tune 720BT's battery power is 500mAh, 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. JBL Tune 720BT's battery can be recharged and used over again.
The Bose QuietComfort 45 too have a rechargeable battery. JBL Tune 720BT can be used wirelessly, wireless devices allow you more freedom of movement. The Bose QuietComfort 45 also can be used wirelessly
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 Tune 720BT has a v5.3
Bose QuietComfort 45 has a Bluetooth version of v5.1. Newer versions provide faster data transfers. JBL Tune 720BT 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. Bose QuietComfort 45 too have USB TYPE-C
JBL Tune 720BT 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 Tune 720BT can connect at a 10meters distance via Bluetooth or infrared to another device.
The Bose QuietComfort 45 can connect at a 9meters distance via Bluetooth
JBL Tune 720BT have only 2 microphones, more microphones result in better sound quality and enable the device to filter out background noise. The Bose QuietComfort 45 microphones are only 4. The magnitude of the analog or digital output signal from the microphone with that input stimulus is a measure of its sensitivity.
Microphone sensitivity is a measurement of a microphone's efficiency as a transducer (how well it converts acoustical energy to electrical energy). JBL Tune 720BT microphone sensitivity is measured at -40dBV/Pa
JBL Tune 720BT 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 Tune 720BT 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.
The Bose QuietComfort 45 too have a control panel on them. JBL Tune 720BT can be used as a headset. A headset is one headphone or pair with a built-in microphone.
