Ingress protection ratings refer to the rank of protection offered by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value refers to protection against solids say dust, followed by the one that refers to resistance against liquids (sweat).
Scoring IPX4, the JBL Tune Flex's rating is read as, the first number of X denotes that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Compared to the JBL Tune Flex, JBL Live Pro 2 have a rating of IPX5 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
JBL Tune Flex has a lower liquid rating than JBL Live Pro 2

JBL Tune Flex have stereo speakers, what this means is that JBL Tune Flex's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. The JBL Live Pro 2 also have stereo speakers
ANC uses advanced technology to actively counter noise. ANC works when, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out.
Simply put, it's like taking +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make zero which results in a reduced level of noise.
The JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to overcome background noise. The JBL Live Pro 2 too have Active Noise Cancellation which makes both devices ideal for plane rides and rush hour commutes.
The JBL Tune Flex and JBL Live Pro 2 operate with different noise cancellation modes, pick the noise cancellation type that suits your commute or that enhances your relaxation time.

A driver unit is basically a mini speaker that makes sound in the earbuds, the unit size corellates with the loudness of the device. JBL Live Pro 2 driver unit is 11mm in diameter,
which means that they have a smaller driver unit than that of JBL Tune Flex by 1mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not indicate that they produce better quality sound.
The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low recognizable frequencies and if it alters the signal on its way through. JBL Live Pro 2's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio device produces high audible frequencies and if it adjustments to the signal while at it. JBL Live Pro 2's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
The sound pressure level, is the level of pressure of sound, 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 Live Pro 2's sound pressure level measurement is 93dB/mW. How loud a device 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 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 usually given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often. JBL Live Pro 2's battery life is
more than that of JBL Tune Flex by 2 hours
. Every time you recharge your earbuds, they get a little less listening time.
The effect is barely noticeable at first, but over time, your wireless earbuds will have shorter listening time. This is given by the vendor, and the JBL Tune Flex's case has a full charge of 24 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go several times before recharging the case itself.

equal to that of the JBL Tune Flex
JBL Tune Flex support AAC, a codec that is used for Bluetooth audio.
It supports 24-bit audio at 250kbps. Since it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the JBL Tune Flex will work fine with your iPad.
If you are planning on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well. JBL Tune Flex have 4 microphones. JBL Live Pro 2 microphones are 6,
more than that of JBL Tune Flex by 2
. More microphones record better sound quality and help the device to filter out background sounds.
JBL Tune Flex use a noise-canceling microphone, these microphones are designed to filter out noise from the earbuds' sound. The JBL Live Pro 2 too have a noise-canceling microphone. This is useful in noisy environments.
The JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The extent of the analog or digital output signal from the microphone with its input stimulus is a measure of its sensitivity. It's the 'loudness' of the voice that the earbud microphone can pick up.
The JBL Live Pro 2 microphone sensitivity is measured at -38dBV/Pa. Microphone sensitivity is a measurement of a microphone's efficiency on how well it converts sounds to electrical energy. JBL Tune Flex support ambient sound mode, which uses microphones to pass through ambient sound to still be heard even while wearing the earbuds
