Ingress protection ratings refer to the level of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value refers to protection against solids such as dust, followed by the one that refers to resistance against liquids (water).
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, Razer Hammerhead True Wireless Pro 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

The Razer Hammerhead True Wireless Pro also have stereo speakers
ANC makes use of more advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
JBL Tune Flex have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background sounds.
The Razer Hammerhead True Wireless Pro too have ANC which makes either of the devices ideal for flights and rush hour travels. Each work with different noise cancellation modes, pick the mode that you prefer for commute or that enhances your chill time.

The driver unit is basically a mini speaker that makes sound in the device, the unit size corellates with the loudness of the earbuds.
Razer Hammerhead True Wireless Pro driver unit is 10mm in diameter, which implies that they have a smaller driver unit than that of JBL Tune Flex by 2mm , 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 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 produces low frequencies that can be heard, and if it alters the signal while at it.
Razer Hammerhead True Wireless Pro's lowest frequency is at 20Hz, this implies that both devices can make sound with equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device makes high human frequencies and if it changes to the signal on its way through.
Razer Hammerhead True Wireless Pro's highest frequency is at 20,000Hz, this means 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 before recharge. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings.
Razer Hammerhead True Wireless Pro's battery life is less than that of JBL Tune Flex by 4 hours . Each time you recharge your earbuds, they get a little less listening time. The effect is barely noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to.
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 a longer battery life allows you to recharge your earbuds on the go several times before having to recharge the case itself.
Razer Hammerhead True Wireless Pro's charging case has a battery life of 16 hours, less than that of JBL Tune Flex by 8 hours
