Ingress protection ratings is the rank of protection offered by an enclosure, against solids and liquids. In the format of IPXX, 'X' represents a number The first value represents protection against solids say dust, followed by the one that 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 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, 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,
they both have the same rating against liquids
JBL Tune Flex have a weight of 9.6g . We take in account a lower weight better for the reason that lighter devices are more comfortable to transport.
Sony LinkBuds S, at 9.6g
have the same weight as the JBL Tune Flex
For a device to be true wireless it should have no cables linking any part of the device together, JBL Tune Flex are true wireless for this matter since they don't have cables. This is an important difference since wireless earbuds have cables connecting the 2 earbuds together. Sony LinkBuds S also is true wireless since it has no cables connecting the two earbuds together.
JBL Tune Flex are resistant to sweat
Sony LinkBuds S's resistance to sweat makes both devices ideal 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 separate channels on both left and right sides, this creates a richer sound and a better listening experience. The Sony LinkBuds S also have stereo speakers
ANC uses advanced kind of tech to reduce ambient sounds. How it works, it studies the sound pattern of incoming noise and after generates a mirror signal to cancel it out.
In simple terms, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make 0 resulting in a reduced level of noise.
JBL Tune Flex have ANC enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to outcompete background noise. The Sony LinkBuds S too have ANC making both earbuds ideal for flights and rush hour travels.
The JBL Tune Flex and Sony LinkBuds S operate with different noise cancellation types, pick the mode that suits your commute or that suites your chill time.

JBL Tune Flex driver unit is 12mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is basically a mini speaker that makes sound in the earbuds, its size corellates with the sound produced by the device. Sony LinkBuds S driver unit is 5mm in diameter,
which means that they have a smaller driver unit than that of JBL Tune Flex by 7mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers can generate louder sound, but this does not indicate 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 frequencies that can be heard, and if it alters the signal on its way through. Sony LinkBuds S's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device produces high recognizable frequencies and if it makes any changes to the signal on its way through.
Sony LinkBuds S's highest frequency is at 40,000Hz, this implies that
Sony LinkBuds S can generate a clearer and crispier treble than the JBL Tune Flex
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 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
. Every time you recharge your earbuds, they get a little less listening 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 manufacturer, and JBL Tune Flex's case is said to have 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 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
It takes 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. Sony LinkBuds S takes 2 hours to fully charge the battery,
equal to that of the JBL Tune Flex
JBL Tune Flex have a battery level indicator, an indicator alerts you when the device has a low battery. The battery indicator lights display the charging status of your device and charging case.
Sony LinkBuds S too have a battery level indicator, charging indicators allow you to tell the charging state of your earbuds, whether fully charged, or the battery is running low. JBL Tune Flex support USB TYPE-C, a standard connector for transmitting both data and power through a single cable. Sony LinkBuds S too support USB TYPE-C.
This USB-C plug comes along with most current electronics. The JBL Tune Flex have Bluetooth version of 5.2, Bluetooth is a wireless technology standard that enables data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Sony LinkBuds S 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 to connect 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 provides better results than other codecs at a similar bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the JBL Tune Flex will work well with your iPhone. 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.
While the Sony LinkBuds S microphones are 6,
more than that of JBL Tune Flex by 2
. More microphones record better sound quality and enable the earbuds to filter out noise. JBL Tune Flex use a noise-canceling microphone, these microphones are intended to reduce background sounds from the desired sound. 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 pick up. The JBL Tune Flex support ambient sound mode, which uses microphones to channel ambient noises to still be heard even when wearing them
