The JBL Tune 520BT have a weight of 160g, 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 because lighter devices are more comfortable to transport. 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 Tune 520BT are one of those. JBL Tune 520BT 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 Tune 520BT'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.
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 520BT comes with a 1.2meters cable.
On-ear headphones have smaller earpads that sit on top of your ears, this JBL Tune 520BT 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 Tune 520BT 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.
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 JBL Tune 520BT 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 device reproduces low audible frequencies and if it makes any changes to the signal on the way through. JBL Tune 520BT'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 an audio component reproduces high audible frequencies and if it changes to the signal while at it.
JBL Tune 520BT'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 520BT'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 520BT driver unit is 30mm 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 experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. JBL Tune 520BT'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 520BT's battery life is 57 hours
It takes 2 hours to fully charge the JBL Tune 520BT'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 520BT have a battery level indicator, an indicator shows you when the device has a low battery. The battery indicator lights show the charging status of your headphones.
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. JBL Tune 520BT's battery power is 450mAh, 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 520BT's battery can be recharged and used over again. JBL Tune 520BT can be used wirelessly, wireless devices allow you more freedom of movement. 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 520BT has a v5.3
JBL Tune 520BT 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 Tune 520BT 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 520BT can connect at a 10meters distance via Bluetooth or infrared to another device. JBL Tune 520BT have only 2 microphones, more microphones result in better sound quality and enable the device to filter out background noise. 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 520BT microphone sensitivity is measured at -29dBV/Pa
JBL Tune 520BT 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 520BT 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 Tune 520BT 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 Tune 520BT have a warranty period of 1 years
