Jbl Tune Flex Vs. Sony Wf 1000Xm4 Review

IP 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 (sweat).

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 value 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 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 easier to carry.

The Sony WF 1000XM4, at 7.1g weigh less than the JBL Tune Flex with a difference -2.5g True wireless devices have no cables connecting 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 distinction as some wireless earbuds have cables connecting the pair of earbuds together. Sony WF 1000XM4 also is true wireless since it has no wires linking the 2 earbuds . JBL Tune Flex have sweat resistance Sony WF 1000XM4's resistance to sweat makes both devices good for use during 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 independent channels on both left and right sides, this creates a richer sound and a better listening experience.

Both Sony WF 1000XM4 and JBL Tune Flex have stereo speakers ANC utilises more advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern of incoming noise and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.

The JBL Tune Flex have ANC allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to overcome background sounds. The Sony WF 1000XM4 too have Active Noise Cancellation which makes both earbuds ideal for plane rides and morning travels. Each work with different noise cancellation settings, pick the setting that suits your travel or that suites your relaxation time.

JBL Tune Flex stay tightly in place, this creates a sound covering that reduces background noise while preventing the earbuds voice audio from leaking out . Both of these devices have passive noise reduction this implies that they limit ambient noise instead of actively using ANC to cancel it out. The JBL Tune Flex have a unit size of 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 determines the sound made by the earbuds.

Sony WF 1000XM4 driver unit is 6mm in diameter, which means 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 are capable of generating louder sound, but this does not imply 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 device produces low frequencies that can be heard, and if it alters the signal on its way through.

Sony WF 1000XM4's lowest frequency is at 20Hz, this implies 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 component generates high recognizable frequencies and if it makes any changes to the signal on its way through. Sony WF 1000XM4's highest frequency is at 40,000Hz, this implies that Sony WF 1000XM4 can generate 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.

Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. How loud a device is can be perceived differently by different 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 before recharge.

A device's battery life is usually given by the manufacturer, and with longer battery life, 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 playing time. The effect is barely noticeable at first, but over time, your wireless earbuds will have shorter listening time.

This is given by the vendor, and JBL Tune Flex's case is said to have a charge of 24 hours. A charging case with more battery hours enables you to recharge your earbuds on the go several 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 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 when they have been unused for extended periods. Sony WF 1000XM4 takes 1.5 hours to fully charge the battery, less than that of JBL Tune Flex by 0.5 hours JBL Tune Flex have a battery level indicator, an indicator shows you when the earbuds has a low battery. Its lights show the charging state of your device and case.

Sony WF 1000XM4 too have a battery level indicator, charging indicators enable you tell the charging state of your earbuds, if charged fully, or the battery is running low. JBL Tune Flex have USB TYPE-C, a standard connector for transmitting both data and power in a single cable. Sony WF 1000XM4 too have 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 movement 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 that is used for Bluetooth audio. It supports 24-bit audio at 250kbps.

Since it uses psychoacoustic modeling, it provides 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 iPad. If you intend on using these with Android you need to pay even closer attention to codec support for if they only have AAC they won't provide the best audio quality possible, 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.

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. The JBL Tune Flex have a noise-canceling microphone, these microphones are designed to reduce noise from the desired sound. The Sony WF 1000XM4 too have a noise-canceling microphone.

Especially useful in noisy environments. 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 sound that the earbud microphone can pick up.
