Ingress protection ratings refer to the level of protection offered by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, followed by the one that refers to protection against liquids (sweat).
Having a value of IPX5, the Boult Audio Z40's rating for solids indicates 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, 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
The Boult Audio Z40 have a weight of 40g . We consider a lower weight best for the reason that lighter devices are more comfortable to carry.
The Marshall Minor III, at 8g
are lighter than the Boult Audio Z40 by -32g
For a device to be true wireless it must have no wires linking any part of the device together, Boult Audio Z40 are true wireless for this matter since they have no cables. This is a major difference since wireless earbuds have wires connecting the two earbuds .
Marshall Minor III also is true wireless because it has no wires linking the 2 earbuds .
The Boult Audio Z40 come with wingtips, these are commonly used for earbuds for workouts and come as an optional add-on to the separate silicone ear tip for a better fit. Boult Audio Z40 are resistant to sweat

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 Marshall Minor III and Boult Audio Z40 have stereo speakers
The Boult Audio Z40 sit well in place, this creates a sound seal that tones down background sounds and also prevents the device sound from leaking out at the same. 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 the component that produces sound in the earbuds, its size corellates with the sound made by 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
, as many tend to believe 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 can generate louder sound, but this does not indicate that they produce better quality sound.
Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it makes any changes to the signal on its way through. Marshall Minor III's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device generates high recognizable frequencies and if it adjustments 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
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. Marshall Minor III's battery life is
less than that of Boult Audio Z40 by 5 hours
. Each time you recharge your earbuds, they get a little less playing time. The effect is barely noticeable at first, but over a few years, your wireless earbuds will have shorter listening time.
This is given by the vendor, and the Boult Audio Z40's case is said to have a charge of 50 hours. A charging case with a longer battery life enables you to recharge your earbuds on the go multiple 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

This USB-C plug comes along with 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 transfers between devices placed in close proximity, 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 connecting 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 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. While the Marshall Minor III microphones are 2,
equal to that of the Boult Audio Z40
. More microphones record better sound quality and help the device to filter out noise. The Boult Audio Z40 have in/on-ear detection, the sensors in the device can detect when they are removed from your ears .
The Marshall Minor III support in/on-ear detection, automatically pauses your music, or audiobook when you remove earbuds from your ears improving your listening experience.
