IP ratings refer to the rating of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value represents protection against solids say dust, followed by the one that refers to resistance against liquids (water).
Having a value of 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. Compared 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 best because lighter devices are easier to transport.
Marshall Minor III, at 8g
are lighter than the Boult Audio Z40 by -32g
True wireless devices have no wires connecting any part of the device together, Boult Audio Z40 are true wireless for this matter since they have no cables. This is a major distinction since wireless earbuds have cables linking the 2 earbuds .
Marshall Minor III also is true wireless since it has no wires connecting the two earbuds together. The Boult Audio Z40 come with 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
Marshall Minor III's resistance to sweat makes both devices ideal for use while doing sports such as long-distance running, marathons, cardio sweat workouts , 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 Marshall Minor III also have stereo speakers
The Boult Audio Z40 sit well in place, this creates a sound seal that reduces background noise and also prevents the device sound from leaking out at the same.
Boult Audio Z40 have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass. The driver unit is the component that produces sound in the device, 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 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 inidcates how well an audio device generates low audible frequencies and if it alters the signal on its way through. Marshall Minor III's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio device makes high human frequencies and if it changes to the signal while at it.
Marshall Minor III's highest frequency is at 20,000Hz, this means that
both devices generate equal treble
The 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 commonly given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often. 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 not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to. The battery life of the charging case is given by the manufacturer, and Boult Audio Z40's case is said to have a full charge of 50 hours. A charging case with a longer battery life 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 for the first time. 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, an industry-standard connector for transmitting both data and power in a single cable.
Marshall Minor III too have USB TYPE-C. This USB-C plug comes along with most current laptops, phones, and tablets. 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. The 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. Because it uses psychoacoustic modeling, it can provide 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 fine with your iPhone.
If you intend 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 Marshall Minor III microphones are 2,
equal to that of the Boult Audio Z40
. More microphones record better sound quality and help the earbuds to filter out background sounds.
The Boult Audio Z40 support in/on-ear detection, the sensors in the device can detect when they are removed from your ears .
The Marshall Minor III too support in/on-ear detection, automatically pauses your music, or audiobook when you remove earbuds from your ears saving battery life. The Boult Audio Z40 support fast charging. Usually, technologies like Qualcomm’s Quick Charge, are used to reduce the amount of time it takes to fully charge a device.
