Ingress protection ratings is the level of protection offered by an enclosure, against dust and water. 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 (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 of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Compared 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

Both Bowers & Wilkins PI7 and JBL Tune Flex have stereo speakers
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. In simple terms, it's like taking +1 (noise) and producing -1 (counter sound by the device) to make zero hence "diluting" the noise.
JBL Tune Flex have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise. Bowers & Wilkins PI7 too have ANC which makes both devices ideal for flights and morning travels. The JBL Tune Flex and Bowers & Wilkins PI7 operate with different noise cancellation settings, pick the noise cancellation type that suits your commute or that suites your relaxation time.
The JBL Tune Flex sit tightly in place, creating an acoustic seal that tones down your environment noise while preventing the device music from leaking out at the same. Both Bowers & Wilkins PI7, and JBL Tune Flex have passive noise reduction this means that they reduce ambient noise without 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.
The driver unit is basically a mini speaker that produces sound in the earbuds, its size corellates with the loudness of 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
, 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 yeah, 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 makes any changes to the signal on its way through. Bowers & Wilkins PI7's lowest frequency is at 10Hz, this implies that
Bowers & Wilkins PI7 can make sound with a juicier bass than the JBL Tune Flex
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component produces high human frequencies and if it adjustments 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
The sound pressure level, 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. 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 more battery hours, 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 earbuds, they get a little less playing time. The effect is not noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to. The battery life of the charging case is given by the manufacturer, and the JBL Tune Flex's case has a charge of 24 hours.
A charging case with a longer battery life enables you to recharge your earbuds on the go multiple 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 requires 2 hours to fully charge the JBL Tune Flex's battery. It is recommended to charge fully 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

Bowers & Wilkins PI7 too have a battery level indicator, charging indicators enable you to tell the charging state of your device, whether fully charged, or the battery is running low.
JBL Tune Flex support USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable. Bowers & Wilkins PI7 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 transfers between devices placed in range, using short-wavelength, ultra-high frequency radio waves. Bowers & Wilkins PI7 has a Bluetooth version of 5,
older than that of JBL Tune Flex
. Newer versions provide faster data transfers. The 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 used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it provides better results than other codecs at a similar 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 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. While the Bowers & Wilkins PI7 microphones are 6,
more than that of JBL Tune Flex by 2
. More microphones record better sound quality and enable the earbuds to filter out noise.
The JBL Tune Flex have a noise-canceling microphone, these microphones are made to reduce background sounds from the earbuds' sound. The Bowers & Wilkins PI7 too use a noise-canceling type of microphone. Especially useful in noisy environments.
The JBL Tune Flex microphone sensitivity is measured at -38dBV/Pa. The amount 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 microphone can pick up.
