IP ratings refer to the level of protection given by a casing, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids such as dust, while the second refers to protection against liquids (water).
Scoring IPX4, the JBL Tune Flex's rating for solids indicates 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. 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 Tune Flex has a lower liquid rating than JBL Reflect Aero
The JBL Tune Flex have a weight of 9.6g . We take in account a lower weight best for the reason that lighter devices are easier to transport.
JBL Reflect Aero, at 13g
weigh more than the JBL Tune Flex with a difference of 3.4g
For a device to be true wireless it must 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 a major difference as some wireless earbuds have wires linking the two earbuds together. JBL Reflect Aero also is true wireless since it has no wires connecting the pair of earbuds .
JBL Tune Flex have sweat resistance
JBL Reflect Aero's resistance to sweat makes both devices good 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 independent channels on both left and right sides, creating a richer sound and a better listening experience.
The JBL Reflect Aero also have stereo speakers
ANC uses more advanced kind of tech to actively cancel noise. How it works, it listens to the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like having +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 Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to overcome background noise. JBL Reflect Aero too have Active Noise Cancellation which makes both devices ideal for plane rides and rush hour commutes. The JBL Tune Flex and JBL Reflect Aero operate with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that enhances your relaxation time.

The JBL Tune Flex driver unit is 12mm in diameter, the bigger the unit the more powerful, and can produce better bass. A driver unit is basically a mini speaker that makes sound in the earbuds, its size determines the sound produced 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
, 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 are capable of generating louder sound, but this does not indicate that they produce 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 frequencies that can be heard, and if it makes any changes to the signal on its way through.
JBL Reflect Aero's lowest frequency is at 20Hz, this means that
both devices produce equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response tells how well an audio component makes high human frequencies and if it makes any changes to the signal on its way through. JBL Reflect Aero's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
The sound pressure level, is the pressure level 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 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 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
. 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 enables you to recharge your earbuds on the go multiple times before having to recharge the case itself. JBL Reflect Aero's charging case has a battery life of 16 hours,
less than that of JBL Tune Flex by 8 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 for the first time. JBL Reflect Aero takes 1.5 hours to fully charge the battery,
less than that of JBL Tune Flex by 0.5 hours
JBL Tune Flex have a battery level indicator, an indicator alerts you when the device has a low battery. Its lights show the charging state of your device and case.
JBL Reflect Aero too have a battery level indicator, charging indicators allow you tell the charging state of your earbuds, if charged fully, or the battery is running low. The JBL Tune Flex use USB TYPE-C, a standard connector for transmitting both data and power through a single cable. JBL Reflect Aero too support USB TYPE-C.
This USB-C plug is part and parcel of most current laptops, phones, and tablets. JBL Tune Flex have Bluetooth version of 5.2, Bluetooth is a wireless technology standard that allows data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves. JBL Reflect Aero has a Bluetooth version of 5.2,
equal to that of the JBL Tune Flex
. Newer versions provide faster data transfers.
The JBL Tune Flex have a 10meters distance connecting via Bluetooth. JBL Reflect Aero have a maximum range of 10meters,
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 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 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. While the JBL Reflect Aero microphones are 6,
more than that of JBL Tune Flex by 2
. More microphones result in better sound quality and help the earbuds to filter out background sounds. JBL Tune Flex have a noise-canceling type of microphone, these microphones are designed to reduce background sounds from the earbuds' sound.
The JBL Reflect Aero too have a noise-canceling type of microphone. Especially useful in noisy areas. 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 calculation of its sensitivity. It's the 'loudness' of the voice that the earbud microphone can recognize. The JBL Tune Flex support ambient sound mode, which uses microphones to pass through ambient sound to still be heard even when wearing them
