IP ratings is the level of protection given by a casing, against solids and water. In the format of IPXX, 'X' represents a number The first value refers to protection against solids say dust, while the second refers to resistance against liquids (water).
Having a value of IPX4, the JBL Tune Flex's rating is read as, the first number 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. In comparison to the JBL Tune Flex, Sony LinkBuds S have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,

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.
Both Sony LinkBuds S and JBL Tune Flex have stereo speakers
ANC makes use of advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make 0 hence "diluting" the noise.
JBL Tune Flex have ANC enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to overcome background noise.

JBL Tune Flex driver unit is 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 dictates the loudness of the device.
Sony LinkBuds S driver unit is 5mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 7mm
, a common assumption 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 mean that they produce better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it alters the signal while at it.
Sony LinkBuds S's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device makes high recognizable frequencies and if it makes any adjustments to the signal while at it. Sony LinkBuds S's highest frequency is at 40,000Hz, this implies that
Sony LinkBuds S produce a clearer and crispier treble than the JBL Tune Flex
The sound pressure level, is the pressure level 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 more battery hours, you get to use it for longer and requires fewer chargings. Sony LinkBuds S's battery life is
less than that of JBL Tune Flex by 2 hours
. Each time you recharge your device, they get a little less playing time.
The effect is not noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to. The battery life of the charging case is given by the vendor, and JBL Tune Flex's case is said to have a charge of 24 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go several times before recharging the case itself.
Sony LinkBuds S's charging case has a battery life of 14 hours,
less than that of JBL Tune Flex by 10 hours

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. Sony LinkBuds S 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. Since it uses psychoacoustic modeling, it can provide better results than other codecs at the same bit rate.

If you intend on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well. The Sony LinkBuds S 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. Sony LinkBuds S 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 microphone, these microphones are made to reduce background sounds from the desired sound.
