Ingress protection ratings refer to the rank of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value refers to protection against solids say dust, while the second refers to protection against liquids (sweat).
Having a value of IPX4, the JBL Tune Flex's rating for solids indicates that no data available to specify a protection rating, and the second number 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, Jabra Evolve2 Buds have a rating of IP54 meaning that
ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety
and that of liquids is that,
they both have the same rating against liquids
The JBL Tune Flex have a weight of 9.6g . We consider a lower weight better for the reason that lighter devices are more comfortable to move with.
Jabra Evolve2 Buds, at 10.8g
weigh more than the JBL Tune Flex by of 1.2g
For a device to be true wireless it should have no wires linking any part of the device together, JBL Tune Flex are true wireless for this case since they don't have cables. This is a key difference as some wireless earbuds have wires connecting the 2 earbuds together. Jabra Evolve2 Buds also is true wireless since it has no cables connecting the pair of earbuds .
JBL Tune Flex have sweat resistance
Jabra Evolve2 Buds's resistance to sweat makes both devices fit for use while doing sports such as long-distance running, marathons, training in workout bodysuits, etc
JBL Tune Flex 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 Jabra Evolve2 Buds and JBL Tune Flex have stereo speakers
ANC utilises more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) and adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
The JBL Tune Flex have ANC allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the device volume to outcompete background sounds. Jabra Evolve2 Buds too have ANC which makes both devices ideal for flights and morning travels. The JBL Tune Flex and Jabra Evolve2 Buds work with different noise cancellation settings, pick the setting that you prefer for travel or that enhances your relaxation time.
The JBL Tune Flex stay well in place, creating an acoustic seal that tones down background sounds well as preventing the earbuds sound from leaking out .

The JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, and can produce better bass. A driver unit is basically a mini speaker that makes sound in the device, the unit size dictates the sound produced by the device.
Jabra Evolve2 Buds driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 6mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it alters the signal on its way through.
Jabra Evolve2 Buds's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component makes high human frequencies and if it adjustments to the signal on its way through. Jabra Evolve2 Buds's highest frequency is at 20,000Hz, this implies that
both devices generate equal treble
The sound pressure level, 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.
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 more battery hours, you get to use it for longer and requires fewer chargings. Jabra Evolve2 Buds's battery life is
more than that of JBL Tune Flex by 2 hours
. Each time you recharge your earbuds, they get a little less playing time.
The effect is not noticeable at first, but over a few years, your wireless earbuds will have shorter listening time. The battery life of the charging case is given by the vendor, and 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 multiple times before having to recharge the case itself.
Jabra Evolve2 Buds's charging case has a battery life of 21 hours,
less than that of JBL Tune Flex by 3 hours
It takes 2 hours to fully charge the JBL Tune Flex's battery. It is recommended to charge fully the battery before using the earbuds when they have been unused for long periods. Jabra Evolve2 Buds takes 2 hours to fully charge the battery,
equal to that of the JBL Tune Flex
JBL Tune Flex 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 earbuds and case. Jabra Evolve2 Buds too have a battery level indicator, these enable you determine the charging state of your earbuds, whether fully charged, or having a low battery. The JBL Tune Flex have USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable.
Jabra Evolve2 Buds too have USB TYPE-C. This USB-C plug comes along with most current laptops, phones, and tablets. JBL Tune Flex have Bluetooth version of 5.2, Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves.
Jabra Evolve2 Buds has a Bluetooth version of 5.2,
equal to that of the JBL Tune Flex
. Newer versions provide faster data transfers. JBL Tune Flex have a 10meters distance to connect via Bluetooth. Jabra Evolve2 Buds have a maximum range of 20meters,
longer than that of JBL Tune Flex by 10meters
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 provides better results than other codecs at a similar bit rate.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the JBL Tune Flex will work well with your MacBook.
If you intend on using these with Android you need to pay even closer attention to codec support for if they only have AAC they won't provide the best audio quality possible, ensure that they also support aptX HD, LDAC, or LHDC as well. The Jabra Evolve2 Buds support AAC as well. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate.
The JBL Tune Flex have 4 microphones. While the Jabra Evolve2 Buds 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 noise. JBL Tune Flex use a noise-canceling microphone, these microphones are designed to filter out background sounds from the desired sound.
The Jabra Evolve2 Buds too use a noise-canceling microphone. Especially useful in noisy areas. The 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 measure of its sensitivity. It's the 'loudness' of the sound that the earbud microphone can recognize. JBL Tune Flex support ambient sound mode, which uses microphones to channel ambient sound to still be heard even when wearing the earbuds
