IP ratings is the rank of protection given by an enclosure, against solids and liquids. 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 for solids indicates 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. 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
Boult Audio Z40 have a weight of 40g . We consider a lower weight best because lighter devices are easier to move with.
The JBL Wave Beam, at 8.8g
weigh less than the Boult Audio Z40 with a difference -31.2g
True wireless devices have no cables 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 linking the two earbuds together. JBL Wave Beam also is true wireless because it doesn't have cables linking the two earbuds .
Boult Audio Z40 have wingtips, these are reserved for earbuds for workouts and come as an optional add-on to the separate silicone ear tip for a more secure fit.
Boult Audio Z40 are resistant to sweat
JBL Wave Beam's resistance to sweat makes both devices fit for use while doing sports such as 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, this creates a richer sound and a better listening experience. The JBL Wave Beam also have stereo speakers
The Boult Audio Z40 stay tightly in place, creating a sound seal that reduces background noise and also prevents the earbuds music from leaking out .
Both of these devices have passive noise reduction which means that they reduce ambient noise instead of actively using technology to cancel it out.
The Boult Audio Z40 driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is the component 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 implies that they have a smaller driver unit than that of Boult Audio Z40 by 2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound. The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low recognizable frequencies and if it alters the signal on its way through. JBL Wave Beam's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response tells how well an audio component makes high human frequencies and if it makes any 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
Boult Audio Z40's battery life is 10 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 longer battery life, you get to use it for longer and requires fewer chargings. JBL Wave Beam's battery life is
less than that of Boult Audio Z40 by 2 hours
. Every time you recharge your device, they get a little less listening time.
The effect is barely noticeable at first, but over a few years, your wireless earbuds will have shorter listening time. The battery life of the charging case is given by the vendor, and Boult Audio Z40's case has a full charge of 50 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go multiple times before recharging the case itself.
JBL Wave Beam's charging case has a battery life of 24 hours,
less than that of Boult Audio Z40 by 26 hours
It requires 1.5 hours to fully charge the Boult Audio Z40's battery. It is recommended to charge fully the battery before using the earbuds for the first time. JBL Wave Beam takes 2 hours to fully charge the battery,
more than that of Boult Audio Z40 by 0.5 hours
The Boult Audio Z40 have USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable.
JBL Wave Beam too support USB TYPE-C. This USB-C plug is part and parcel of most current electronics. The Boult Audio Z40 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows 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 to connect 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.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Boult Audio Z40 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 Boult Audio Z40 have 2 microphones. JBL Wave Beam microphones are 2,
equal to that of the Boult Audio Z40
. More microphones result in better sound quality and enable the earbuds to filter out background sounds.
Boult Audio Z40 support in/on-ear detection, the sensors in the earbuds can detect when they are removed from your ears .
Boult Audio Z40 support fast charging. Most often, technologies like MediaTek’s Pump Express, are used to reduce the amount of time it takes to charge the earbuds. The JBL Wave Beam support fast charging.
This kind is similar to regular charging, just that the battery fills up much faster. Say, with Quick Charge 3.0, the battery is charged to 50% in just 30 minutes. Boult Audio Z40 have a mute function, they have the feature to mute/unmute a conversation directly from the device.
The JBL Wave Beam also have this function. The mute function means that you can turn off the earbuds' microphone, but you can still hear the other party talk. With the Boult Audio Z40, so you can access the volume control, pause, play, mute, etc whichever functions are supported on the earbuds.
