IP ratings refer to the rank of protection offered by a casing, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids say dust, while the second refers to protection 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 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, Bose QuietComfort 2 have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
they both have the same rating against liquids
JBL Tune Flex have a weight of 9.6g . We take in account a lower weight best for the reason that lighter devices are more comfortable to transport.
The Bose QuietComfort 2, at 12.5g weigh more than the JBL Tune Flex by of 2.9g True wireless devices have no wires connecting any part of the device together, JBL Tune Flex are true wireless for this matter since they don't have cables.

JBL Tune Flex have sweat resistance Bose QuietComfort 2'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, what this means is that JBL Tune Flex's speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.
The Bose QuietComfort 2 also have stereo speakers Active noise cancellation uses more advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (noise) and adding -1 (inverted noise) giving zero hence "diluting" the 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 device volume to outcompete background noise. The Bose QuietComfort 2 too have Active Noise Cancellation which makes either of the devices ideal for plane rides and rush hour commutes. Each work with different noise cancellation modes, pick the mode that suits your travel or that enhances your relaxation time.
The JBL Tune Flex sit tightly in place, this creates an acoustic covering that tones down background noise and also prevents the earbuds sound from leaking out . Both of these devices have passive noise reduction which means that both tone down ambient noise instead of actively using technology to cancel it out. 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 the component that makes sound in the earbuds, the unit size determines the loudness of the device.
Bose QuietComfort 2 driver unit is 9.3mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 2.7mm
, 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 yeah, larger drivers can generate 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 a particular audio device generates low recognizable frequencies and if it alters the signal on its way through.
Bose QuietComfort 2's lowest frequency is at 20Hz, this implies that both devices make sound with equal bass The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well an audio device makes high human frequencies and if it adjustments to the signal while at it. Bose QuietComfort 2's highest frequency is at 20,000Hz, this implies that both devices can generate equal treble SPL, 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 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 commonly given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
