IP ratings is the level of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, followed by the one that refers to resistance against liquids (sweat).
Scoring 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 the second value of 5 means 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. In comparison 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
The Boult Audio Z40 have a weight of 40g . We take in account a lower weight better because lighter devices are more comfortable to carry.
The JBL Wave Beam, at 8.8g
are lighter than the Boult Audio Z40 with a difference -31.2g
True wireless devices have no cables linking any part of the device together, Boult Audio Z40 are true wireless for this case since they don't have cables. This is a key distinction as some wireless earbuds have wires connecting the 2 earbuds .
JBL Wave Beam also is true wireless since it has no cables connecting the 2 earbuds together. Boult Audio Z40 have wingtips, these are commonly used for workout earbuds and are usually an optional add-on to the separate silicone ear tip for a better fit.
Boult Audio Z40 are resistant to sweat
JBL Wave Beam's resistance to sweat makes both devices good for use while doing sports such as long-distance running, marathons, training in workout bodysuits, etc
The 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, this creates a richer sound and a better listening experience. The JBL Wave Beam also have stereo speakers

Both of these devices have passive noise reduction this implies that both limit ambient noise without using technology to cancel it out.
The Boult Audio Z40 driver unit is 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 corellates with the loudness of the device. 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
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers can generate louder sound, but this does not indicate that they deliver better quality sound. Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low frequencies that can be heard, and if it alters the signal while at it. JBL Wave Beam's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component generates high human frequencies and if it adjustments to the signal while at it.
JBL Wave Beam's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble

JBL Wave Beam too have USB TYPE-C. This USB-C plug is part and parcel of most current electronics. Boult Audio Z40 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data transfers 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 that is 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 a similar bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Boult Audio Z40 will work well with your iPhone.
If you are planning on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well. The Boult Audio Z40 have 2 microphones. The JBL Wave Beam microphones are 2,
equal to that of the Boult Audio Z40
. More microphones record better sound quality and enable the earbuds to filter out noise.
