Ingress protection 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 represents protection against solids such as dust, followed by the one that refers to resistance 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. 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,
they both have the same rating against liquids
The JBL Tune Flex have a weight of 9.6g . We take in account a lower weight better because lighter devices are easier 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 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 cables. This is an important distinction since wireless earbuds have cables connecting the pair of earbuds together. Sony LinkBuds S also is true wireless since it doesn't have cables linking the two earbuds together.
JBL Tune Flex have sweat resistance
Sony LinkBuds S's resistance to sweat makes both devices good for use while doing sports such as long-distance running, marathons, cardio sweat workouts , 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. Both Sony LinkBuds S and JBL Tune Flex have stereo speakers
ANC utilises advanced technology to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it.
Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving zero resulting in a reduced level of noise.
JBL Tune Flex have ANC allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to overcome background sounds. The Sony LinkBuds S too have Active Noise Cancellation making both devices ideal for flights and morning travels.
Each operate with different noise cancellation types, pick the setting that suits your travel or that suites your relaxation time. The JBL Tune Flex sit tightly in place, this creates an acoustic seal that tones down background noise well as preventing the earbuds sound from leaking out .
Both of these devices have passive noise reduction this means that they tone down ambient noise instead of actively using technology to cancel it out. JBL Tune Flex have a unit size of 12mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that makes sound in the earbuds, its size dictates the sound made by the earbuds. 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 usually have difficulty producing high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low frequencies that can be heard, and if it makes any changes to 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 shows how well a particular audio device produces high audible frequencies and if it changes to the signal on its way through. Sony LinkBuds S's highest frequency is at 40,000Hz, this means that
Sony LinkBuds S can produce a clearer and crispier treble than the JBL Tune Flex
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 usually given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
Sony LinkBuds S's battery life is
less than that of JBL Tune Flex by 2 hours
. Each time you recharge your earbuds, they get a little less listening time. The effect is not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to. This is given by the vendor, and JBL Tune Flex's case has a full charge of 24 hours.
A charging case with more battery hours enables you to recharge your earbuds on the go many times before having to recharge 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 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.
Sony LinkBuds S takes 2 hours to fully charge the battery,
equal to that of the JBL Tune Flex
The JBL Tune Flex have a battery level indicator, an indicator notifies you when the earbuds has a low battery. The battery indicator lights indicate the charging state of your device and case. Sony LinkBuds S too have a battery level indicator, charging indicators enable you tell the charging state of your device, whether fully charged, or the battery is running low.
JBL Tune Flex have USB TYPE-C, a standard connector for transmitting both data and power through a single cable. Sony LinkBuds S too use USB TYPE-C. This USB-C plug is part and parcel of most current laptops, phones, and tablets.
The JBL Tune Flex have Bluetooth version of 5.2, Bluetooth is a wireless technology standard that enables data movement between devices placed in range, 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 that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide 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 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. JBL Tune Flex have 4 microphones. 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 device to filter out background sounds.
JBL Tune Flex have a noise-canceling type of microphone, these microphones are intended to filter out noise from the desired sound. 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 measure of its sensitivity.
It's the 'loudness' of the sound that the earbud microphone can recognize. JBL Tune Flex support ambient sound mode, which uses microphones to pass through ambient noises so that they can still be heard even while wearing them
The Sony LinkBuds S support ambient sound mode as well, helpful when you want to listen to music while being aware of your surrounding, for example when you’re having a run but would still want to hear traffic.

Say, with Quick Charge 3.0, the battery is charged to 50% in just 30 minutes. The JBL Tune Flex support multipoint of 2 connections, the multipoint feature allows you to link to more than one Bluetooth device and switch between them. For example, you can easily switch calls from one device to another without manually disconnect and reconnect.
JBL Tune Flex have a mute function, they support the option to mute/unmute a conversation directly from the earbuds. The Sony LinkBuds S too support the mute function. The mute function means that you unilaterally turn off the earbuds' microphone, but you can still hear the other party's voice.
