IP ratings refer to the level of protection offered by an enclosure, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, followed by the one that refers to protection against liquids (water).
Having a value of IPX4, the JBL Tune Flex's rating for solids indicates that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

JBL Tune Flex have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience. Active noise cancellation makes use of advanced kind of tech to reduce unwanted ambient sounds.
How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) and producing -1 (counter sound by the device) giving zero hence "diluting" the noise.
The JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears since you don't need to crank up the earbuds volume to outcompete background noise.

The JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, and can produce better bass. The driver unit is basically a mini speaker that produces sound in the earbuds, its size dictates the loudness of the device. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device produces high human frequencies and if it changes to the signal while at it. SPL, is the level of pressure of sound, measured in decibels, dB, JBL Tune Flex's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average for a single charge. A device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.

The JBL Tune Flex have a 10meters distance connecting via Bluetooth. JBL Tune Flex 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 the same bit rate.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the JBL Tune Flex will work well with your iPad.
If you intend on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well. The JBL Tune Flex have 4 microphones. The JBL Tune Flex use a noise-canceling type of microphone, these microphones are designed to reduce background sounds from the desired sound.
JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The size of the analog or digital output signal from the microphone with its input stimulus is a calculation of its sensitivity. It's the 'loudness' of the sound that the microphone can pick up.
The JBL Tune Flex support ambient sound mode, which uses microphones to channel ambient noises so that they can still be heard even while wearing them
