IP ratings is the rating of protection given by a casing, against dust and water. The letters 'IP' are followed by two values The first value refers to protection against solids such as dust, while the second refers to resistance against liquids (sweat).
Having a value of IPX4, the JBL Tune Flex's rating is read as, the first value of X denotes 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
JBL Tune Flex have a weight of 9.6g . We consider a lower weight better because lighter devices are more comfortable to carry.
Jabra Evolve2 Buds, at 10.8g
are heavier than the JBL Tune Flex with a difference of 1.2g
True wireless devices have no cables connecting any part of the device together, JBL Tune Flex are true wireless for this case since they don't have wires. This is an important distinction as some wireless earbuds have cables linking the 2 earbuds .
Jabra Evolve2 Buds also is true wireless since it has no cables linking the two earbuds together. JBL Tune Flex have sweat resistance
Jabra Evolve2 Buds's resistance to sweat makes both devices good for use while doing sports such as long-distance running, marathons, cardio sweat workouts , etc
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, this creates a richer sound and a better listening experience.
The Jabra Evolve2 Buds also have stereo speakers
Active noise cancellation utilises advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) to make 0 resulting in a reduced level of noise.
The JBL Tune Flex have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to outcompete background noise. Jabra Evolve2 Buds too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour travels. The JBL Tune Flex and Jabra Evolve2 Buds work with different noise cancellation types, pick the mode that you prefer for commute or that suites your chill time.
The JBL Tune Flex sit well in place, creating an acoustic covering that tones down your environment noise and also prevents the device sound from leaking out .
Both Jabra Evolve2 Buds, and JBL Tune Flex have passive noise reduction this means that they reduce ambient noise without using ANC to cancel it out. The JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, therefor producing better bass. The driver unit is basically a mini speaker that makes sound in the earbuds, its size determines the loudness of the earbuds.
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
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound. The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low recognizable frequencies and if it makes any changes to 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 measures if and 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 can generate equal treble
SPL, 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.
The JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge. 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. Jabra Evolve2 Buds's battery life is
more than that of JBL Tune Flex by 2 hours
. Every time you recharge your device, they get a little less playing time.
The effect is not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to. This is given by the vendor, and the JBL Tune Flex's case has a charge of 24 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go many times before recharging 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 requires 2 hours to fully charge the JBL Tune Flex's battery. It is highly adivsable to fully charge the battery before using the earbuds when they have been in storage 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 notifies you when the device has a low battery.
Its lights indicate the charging status of your device and case. Jabra Evolve2 Buds too have a battery level indicator, these allow you to tell the charging state of your device, if charged fully, or having a low battery. JBL Tune Flex support USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable.
Jabra Evolve2 Buds too have USB TYPE-C. This USB-C plug comes along with most current laptops, phones, and tablets. The JBL Tune Flex have Bluetooth version of 5.2, Bluetooth is a wireless technology standard that allows data movement 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 connecting 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. Since 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 MacBook.
If you intend on using these with Android , 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 enable the device to filter out background sounds. The JBL Tune Flex have a noise-canceling microphone, these microphones are designed to reduce noise from the desired sound.
The Jabra Evolve2 Buds too use a noise-canceling type of 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 microphone can pick up. The JBL Tune Flex support ambient sound mode, which uses microphones to channel ambient sound so that they can still be heard even when wearing them
