IP ratings is the level of protection offered by a casing, against solids and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, followed by the one that refers to resistance 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. In comparison to the JBL Tune Flex, JBL Reflect Aero have a rating of IP68 meaning that
they are completely dust proof
and that of liquids is that,
JBL Reflect Aero has a higher liquid rating than JBL Tune Flex

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 JBL Reflect Aero also have stereo speakers
ANC makes use of advanced technology to actively cancel noise. ANC works when, it listens to the sound pattern of incoming noise and after inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
The JBL Tune Flex have ANC 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 sounds. JBL Reflect Aero too have Active Noise Cancellation making either of the earbuds ideal for plane rides and rush hour travels. Each operate with different noise cancellation modes, pick the noise cancellation type that suits your travel or that suites your relaxation time.
The JBL Tune Flex stay well in place, creating a sound covering that tones down your environment noise while preventing the earbuds voice audio from leaking out .
Both JBL Reflect Aero, and JBL Tune Flex have passive noise reduction which implies that they limit ambient noise without using technology to cancel it out. The JBL Tune Flex have a unit size of 12mm in diameter, the bigger the unit the more powerful, therefor producing better bass. A driver unit is the component that makes sound in the earbuds, its size determines the sound made by the earbuds.
JBL Reflect Aero driver unit is 6.8mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 5.2mm
, 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 can generate louder sound, but this does not mean that they deliver better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device produces low recognizable frequencies and if it alters the signal on its way through.
JBL Reflect Aero's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio component generates high human frequencies and if it makes any adjustments to the signal while at it. JBL Reflect Aero'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 Reflect Aero's sound pressure level measurement is 99dB/mW. The sound pressure level, a device is can be considered differently by separate people, so we need to have the means to get a standard 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 commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings. JBL Reflect Aero's battery life is
equal to that of the JBL Tune Flex
. Each time you recharge your device, 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.

equal to that of the JBL Tune Flex
JBL Tune Flex support AAC, a codec 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 fine with your MacBook. If you intend on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well.
JBL Tune Flex have 4 microphones. JBL Reflect Aero 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 have a noise-canceling microphone, these microphones are designed to filter out background sounds from the desired sound.
The JBL Reflect Aero too have a noise-canceling microphone. Especially useful in noisy environments. The JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa.
The vastness 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 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
