IP ratings is the rating of protection offered by a casing, against dust and liquids. In the format of IPXX, 'X' represents a number The first value represents protection against solids say dust, while the second refers to resistance against liquids (water).
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, Marshall Minor III have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
Marshall Minor III has a lower liquid rating than Boult Audio Z40
Boult Audio Z40 have a weight of 40g . We take in account a lower weight better because lighter devices are more comfortable to move with.
Marshall Minor III, at 8g
weigh less than the Boult Audio Z40 with a difference -32g
For a device to be true wireless it should have no wires connecting any part of the device together, Boult Audio Z40 are true wireless for this matter since they have no wires. This is a major difference since wireless earbuds have cables connecting the pair of earbuds .
Marshall Minor III also is true wireless because it has no cables linking the pair of earbuds together. The Boult Audio Z40 come with wingtips, these are reserved for earbuds for workouts and are usually an optional add-on to the separate silicone ear tip for a more secure fit.
Boult Audio Z40 have sweat resistance
Marshall Minor III's resistance to sweat makes both devices good 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, what this means is that Boult Audio Z40's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. The Marshall Minor III also have stereo speakers
Boult Audio Z40 sit well in place, creating an acoustic covering that tones down your environment noise and also prevents the device voice audio from leaking out at the same.
Boult Audio Z40 have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass. The driver unit is the component that produces sound in the earbuds, the unit size determines the loudness of the device. Marshall Minor III driver unit is 12mm in diameter,
making them have a larger 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 usually have difficulty producing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not mean that they produce 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. Marshall Minor III'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 shows how well an audio component makes high human frequencies and if it changes to the signal on its way through.
Marshall Minor III's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble
The 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 commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings. Marshall Minor III's battery life is
less than that of Boult Audio Z40 by 5 hours
. Every time you recharge your device, they get a little less listening time.
The effect is not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to.

A charging case with more battery hours allows you to recharge your earbuds on the go many times before having to recharge the case itself.
Marshall Minor III's charging case has a battery life of 25 hours,
less than that of Boult Audio Z40 by 25 hours
It requires 1.5 hours to fully charge the Boult Audio Z40's battery. It is highly adivsable to charge fully the battery before using the earbuds when they have been in storage for long periods. Marshall Minor III takes 1.5 hours to fully charge the battery,
equal to that of the Boult Audio Z40
The Boult Audio Z40 use USB TYPE-C, a standard connector for transmitting both data and power through a single cable.
Marshall Minor III too have USB TYPE-C. This USB-C plug is part and parcel of most current laptops, phones, and tablets. The 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.
Marshall Minor III 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. Marshall Minor III 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. Since 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 Boult Audio Z40 will work well with your MacBook.
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. The Marshall Minor III microphones are 2,
equal to that of the Boult Audio Z40
. More microphones result in better sound quality and help the earbuds to filter out noise.
Boult Audio Z40 support in/on-ear detection, the sensors in the device can detect when they are removed from your ears so that the music is paused. The Marshall Minor III too support in/on-ear detection, automatically pauses your music, or audiobook when you remove earbuds from your ears improving your listening experience. The Boult Audio Z40 support fast charging.
