Ingress protection ratings is the rating of protection offered by an enclosure, against solids and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, while the second refers to protection against liquids (water).
Scoring IPX5, the Boult Audio Z40's rating is read as, the first number 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, 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 consider a lower weight better because lighter devices are more comfortable to transport.
The 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 don't have cables. This is an important distinction since wireless earbuds have wires connecting the two earbuds .
Marshall Minor III also is true wireless since it has no cables connecting the two earbuds .

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 find it difficult to produce high frequencies so yeah, larger drivers can generate 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 measures if and how well a particular audio device produces low recognizable frequencies and if it makes any changes to the signal on its way through.
Marshall Minor III's lowest frequency is at 20Hz, this means that
both devices produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component produces high recognizable frequencies and if it makes any changes to the signal on its way through. Marshall Minor III's highest frequency is at 20,000Hz, this means that
both devices generate equal treble

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 the same 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 intend 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 enable the device to filter out background sounds. The Boult Audio Z40 support in/on-ear detection, the sensors in the device can detect when removed from your ears .
