Ingress protection ratings is the level of protection offered by an enclosure, against solids and liquids. 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 (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 of liquids 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, Bose QuietComfort Earbuds 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.
Bose QuietComfort Earbuds 2, at 12.5g
are heavier than the JBL Tune Flex with a difference of 2.9g
For a device to be true wireless it must have no wires linking any part of the device together, JBL Tune Flex are true wireless for this case since they have no cables.

JBL Tune Flex have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience. The Bose QuietComfort Earbuds 2 also have stereo speakers
Active noise cancellation makes use of more advanced technology to actively counter noise. How it works, it studies the sound pattern of incoming noise and after generates a mirror signal to counter it.
Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving zero which results in a reduced level of noise.
JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to overcome background noise. Bose QuietComfort Earbuds 2 too have Active Noise Cancellation making either of the earbuds ideal for plane rides and morning commutes.

The JBL Tune Flex driver unit is 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, its size dictates the sound made by the device. Bose QuietComfort Earbuds 2 driver unit is 9.3mm in diameter,
which means 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 yes, larger drivers can generate louder sound, but this does not imply that they produce better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low audible frequencies and if it makes any changes to the signal while at it. Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component generates high audible frequencies and if it changes to the signal while at it.
Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, this means that
both devices can generate 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. 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.

JBL Tune Flex support AAC, a codec 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 a similar 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.
The Bose QuietComfort Earbuds 2 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. JBL Tune Flex have 4 microphones.
Bose QuietComfort Earbuds 2 microphones are 8,
more than that of JBL Tune Flex by 4
. More microphones record better sound quality and help the earbuds to filter out background sounds.

The Bose QuietComfort Earbuds 2 too have a noise-canceling microphone.
This is 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 calculation of its sensitivity.
