IP ratings is the level of protection offered by an enclosure, against solids and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, followed by the one that refers to protection against liquids (sweat).
Having a value of IPX5, the Boult Audio Z40's rating is read as, the first value of X denotes that no data available to specify a protection rating, and of liquids that they can withstand medium pressure jet that's 6.3mm diameter, similar to garden hose from any angle for 3 minutes at a distance of 2.5 to 3 metres. Compared to the Boult Audio Z40, JBL Wave Beam 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,
Boult Audio Z40 has a higher liquid rating than JBL Wave Beam
Boult Audio Z40 have a weight of 40g . We prefer a lower weight best for the reason that lighter devices are more comfortable to carry.
JBL Wave Beam, at 8.8g
weigh less than the Boult Audio Z40 with a difference -31.2g
For a device to be true wireless it must have no wires connecting any part of the device together, Boult Audio Z40 are true wireless for this case since they have no cables. This is a key distinction as some wireless earbuds have cables connecting the two earbuds .
JBL Wave Beam also is true wireless because it has no wires connecting the 2 earbuds .
Boult Audio Z40 have wingtips, these are reserved for workout earbuds and come as an optional add-on to the separate silicone ear tip for a better fit. Boult Audio Z40 have sweat resistance
JBL Wave Beam's resistance to sweat makes both devices ideal for use during long-distance running, marathons, training in workout bodysuits, etc
Boult Audio Z40 are both dustproof and water-resistant.
Boult Audio Z40 have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience. Both JBL Wave Beam and Boult Audio Z40 have stereo speakers
Boult Audio Z40 sit well in place, this creates an acoustic covering that tones down your environment noise and also prevents the earbuds voice audio from leaking out at the same. Both of these devices have passive noise reduction which implies that both tone down ambient noise instead of actively using technology to cancel it out.
The Boult Audio Z40 have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass. The driver unit is basically a mini speaker that produces sound in the device, the unit size dictates the loudness of the earbuds. JBL Wave Beam driver unit is 8mm in diameter,
which means that they have a smaller driver unit than that of Boult Audio Z40 by 2mm
, 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 can generate louder sound, but this does not imply that they produce better quality sound. Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low audible frequencies and if it alters the signal on its way through. JBL Wave Beam's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component makes high human frequencies and if it makes any changes to the signal while at it.
JBL Wave Beam's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
Boult Audio Z40's battery life is 10 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. JBL Wave Beam's battery life is
less than that of Boult Audio Z40 by 2 hours
. Each time you recharge your device, they get a little less listening time.
The effect is not noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to.

JBL Wave Beam too use USB TYPE-C. This USB-C plug comes along with most current electronics. Boult Audio Z40 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that enables data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves.
JBL Wave Beam has a Bluetooth version of 5.2,
older than that of Boult Audio Z40
. Newer versions provide faster data transfers. Boult Audio Z40 have a 10meters distance connecting via Bluetooth. JBL Wave Beam have a maximum range of 10meters,
equal to that of the Boult Audio Z40
Boult Audio Z40 support AAC, a codec 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 the same bit rate.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the Boult Audio Z40 will work well with your iPhone.
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. Boult Audio Z40 have 2 microphones. The JBL Wave Beam microphones are 2,
equal to that of the Boult Audio Z40
. More microphones result in better sound quality and enable the device to filter out noise.
Boult Audio Z40 have in/on-ear detection, the sensors in the device can detect when removed from your ears .
The Boult Audio Z40 support fast charging. Most often, technologies like Qualcomm’s Quick Charge, are used to reduce the amount of time it takes to fully charge the earbuds. Also the JBL Wave Beam support fast charging.
