Ingress protection ratings is the rank of protection given by a casing, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, while the second refers to protection against liquids (water).
Scoring 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 WF 1000XM4 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 because lighter devices are more comfortable to carry.
Sony WF 1000XM4, at 7.1g
are lighter than the JBL Tune Flex by -2.5g
For a device to be true wireless it should have no wires linking any part of the device together, JBL Tune Flex are true wireless for this matter since they have no cables. This is a major distinction since wireless earbuds have wires linking the pair of earbuds .
Sony WF 1000XM4 also is true wireless because it doesn't have wires connecting the 2 earbuds .
JBL Tune Flex are resistant to sweat
Sony WF 1000XM4's resistance to sweat makes both devices good for use while doing sports such as long-distance running, marathons, training in workout bodysuits, etc

ANC utilises advanced technology to actively cancel noise.
How it works, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (noise) then adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
The JBL Tune Flex have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have ANC which makes both earbuds ideal for flights and morning commutes. Each work with different noise cancellation settings, pick the noise cancellation type that you prefer for commute or that suites your chill time. JBL Tune Flex stay well in place, creating an acoustic covering that reduces background sounds and also prevents the device voice audio from leaking out at the same.
Both Sony WF 1000XM4, and JBL Tune Flex have passive noise reduction this means that they limit ambient noise without using ANC to cancel it out. The 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 produces sound in the earbuds, the unit size corellates with the sound produced by the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 6mm
, 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 it's true that, larger drivers can generate louder sound, but this does not imply that they produce better quality sound. The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device generates low audible frequencies and if it alters the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component makes high audible frequencies and if it makes any adjustments to the signal while at it. Sony WF 1000XM4's highest frequency is at 40,000Hz, this means that
Sony WF 1000XM4 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.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. How loud a device is can be perceived differently by separate persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms. 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.
A device's battery life is commonly given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings. Sony WF 1000XM4's battery life is
equal to that of the JBL Tune Flex
. Each time you recharge your device, they get a little less listening time. The effect is not noticeable at first, but over a few years, your wireless earbuds will have shorter listening time.
The battery life of the charging case is given by the vendor, and the JBL Tune Flex's case has a charge of 24 hours. A charging case with more battery hours allows you to recharge your earbuds on the go many times before having to recharge the case itself. Sony WF 1000XM4's charging case has a battery life of 16 hours,
less than that of JBL Tune Flex by 8 hours
It requires 2 hours to fully charge the JBL Tune Flex's battery.
It is recommended to fully charge the battery before using the earbuds when they have been unused for long periods. Sony WF 1000XM4 takes 1.5 hours to fully charge the battery,
less than that of JBL Tune Flex by 0.5 hours
The JBL Tune Flex have a battery level indicator, an indicator alerts you when the device has a low battery. Its lights indicate the charging state of your earbuds and case.
Sony WF 1000XM4 too have a battery level indicator, these enable you to tell the charging state of your earbuds, whether fully charged, or having a low battery. The JBL Tune Flex have USB TYPE-C, a standard connector for transmitting both data and power through a single cable. Sony WF 1000XM4 too use 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 allows data transfers between devices placed in range, using short-wavelength, ultra-high frequency radio waves. Sony WF 1000XM4 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 WF 1000XM4 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.
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 Sony WF 1000XM4 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 WF 1000XM4 microphones are 4,
equal to that of the JBL Tune Flex
. More microphones result in better sound quality and help the earbuds to filter out background sounds. JBL Tune Flex use a noise-canceling microphone, these microphones are intended to filter out noise from the earbuds' sound. The Sony WF 1000XM4 too use a noise-canceling type of microphone.
This is useful in noisy environments. JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The vastness 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 voice 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 when wearing them
The Sony WF 1000XM4 support ambient sound mode as well, it’s useful when you want to listen to music while being aware of what’s happening around you, for example when you’re having a run but still want to hear traffic.
