IP ratings refer to the rating of protection offered by a casing, against solids 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).
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, Bowers & Wilkins PI7 have a rating of IP54 meaning that
ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety
and that of liquids is that,
they both have the same rating against liquids

JBL Tune Flex have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience. The Bowers & Wilkins PI7 also have stereo speakers
ANC utilises more advanced kind of tech to reduce ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to cancel it out.
Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make zero therefore "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. The Bowers & Wilkins PI7 too have Active Noise Cancellation making both earbuds ideal for plane rides and morning commutes.
Each work with different noise cancellation types, pick the setting that you prefer for travel or that suites your relaxation time. JBL Tune Flex stay tightly in place, this creates a sound seal that reduces your environment noise and also prevents the device music from leaking out .
Both of these devices have passive noise reduction which means that both reduce ambient noise instead of actively using ANC to cancel it out. The 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 produces sound in the earbuds, the unit size determines the sound made by the earbuds. Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 2.8mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yes, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
The JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low frequencies that can be heard, and if it alters the signal while at it. Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means that
Bowers & Wilkins PI7 produce a juicier bass than the JBL Tune Flex
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device makes high audible frequencies and if it changes to the signal on its way through. Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble
SPL, 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 for a single charge. A device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often.
Bowers & Wilkins PI7's battery life is
less than that of JBL Tune Flex by 3.5 hours
. Every 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. This is given by the manufacturer, and the JBL Tune Flex's case is said to have a full charge of 24 hours.
A charging case with more battery hours allows you to recharge your earbuds on the go several times before having to recharge the case itself. Bowers & Wilkins PI7's charging case has a battery life of 18 hours,
less than that of JBL Tune Flex by 6 hours
It takes 2 hours to fully charge the JBL Tune Flex's battery. It is recommended to fully charge the battery before using the earbuds for the first time.
Bowers & Wilkins PI7 takes 3 hours to fully charge the battery,
more than that of JBL Tune Flex by 1 hours
The JBL Tune Flex have a battery level indicator, an indicator shows you when the earbuds has a low battery. Its lights display the charging state of your device and case. Bowers & Wilkins PI7 too have a battery level indicator, charging indicators allow you to determine the charging state of your earbuds, whether fully charged, or the battery is running low.
JBL Tune Flex use USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable. Bowers & Wilkins PI7 too support USB TYPE-C. This USB-C plug comes along with most current laptops, phones, and tablets.

older than that of JBL Tune Flex
. Newer versions provide faster data transfers. JBL Tune Flex have a 10meters distance to connect via Bluetooth.
Bowers & Wilkins PI7 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 provides 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 fine with your iPad. If you are planning 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 Bowers & Wilkins PI7 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. Bowers & Wilkins PI7 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 background sounds.
JBL Tune Flex use a noise-canceling microphone, these microphones are designed to filter out noise from the desired sound. The Bowers & Wilkins PI7 too use a noise-canceling microphone. This is useful in noisy environments.
The JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The magnitude 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 microphone can pick up.
