IP ratings refer to the rank of protection offered by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating refers to protection against solids such as dust, while the second refers to protection against liquids (water).
Having a value of IPX4, the JBL Tune Flex's rating for solids indicates 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,
they both have the same rating against liquids
JBL Tune Flex have a weight of 9.6g . We consider a lower weight better for the reason that lighter devices are more comfortable to move with.
The 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 wires. This is a major difference since wireless earbuds have cables linking the 2 earbuds .
Sony LinkBuds S also is true wireless since it doesn't have cables connecting the two earbuds .
JBL Tune Flex have sweat resistance
Sony LinkBuds S's resistance to sweat makes both devices fit for use during long-distance running, marathons, cardio sweat workouts , 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. Both Sony LinkBuds S and JBL Tune Flex have stereo speakers
ANC uses advanced technology to actively counter noise.
How it works, it listens to the sound pattern of incoming noise and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make 0 hence "diluting" the noise.
JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to overcome background noise.
Sony LinkBuds S too have Active Noise Cancellation which makes both earbuds ideal for plane rides and rush hour travels. Each work with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that suites your relaxation time. The JBL Tune Flex sit tightly in place, this creates a sound seal that reduces background noise and also prevents the device music from leaking out at the same.
Both Sony LinkBuds S, and JBL Tune Flex have passive noise reduction this implies that both tone down ambient noise instead of actively using technology to cancel it out. The JBL Tune Flex driver unit is 12mm in diameter, the bigger the unit the more powerful, and can produce better bass. The driver unit is basically a mini speaker that produces 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 mean that they deliver better quality sound. The 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 on its way through.
Sony LinkBuds S's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio device makes 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 implies that
Sony LinkBuds S generate a clearer and crispier treble than the JBL Tune Flex
SPL, is the level of pressure 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.
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. 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 barely noticeable at first, but over time, your wireless earbuds will have shorter listening time. This is given by the manufacturer, and JBL Tune Flex's case has a full charge of 24 hours. A charging case with a longer battery life allows 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 charge fully 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 shows you when the earbuds has a low battery.
Its lights indicate the charging status of your earbuds and case. Sony LinkBuds S too have a battery level indicator, charging indicators enable you to tell the charging state of your device, whether fully charged, or having a low battery. JBL Tune Flex support USB TYPE-C, a standard connector for transmitting both data and power through a single cable.
Sony LinkBuds S too have USB TYPE-C. This USB-C plug is part and parcel of most current electronics. 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 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 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 a similar bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the JBL Tune Flex will work fine with your MacBook.
If you are planning 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 device to filter out noise. JBL Tune Flex use a noise-canceling microphone, these microphones are made to reduce noise from the earbuds' sound.
The 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 pick up.
