IP ratings is the level of protection given by an enclosure, against solids and liquids. The letters 'IP' are followed by two values The first value refers to protection against solids say dust, while the second refers to resistance against liquids (water).
Scoring IPX5, the Boult Audio Z40's rating is read as, the first value of X denotes 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, JLab Go Air have a rating of IP44 meaning that
they are protected against objects greater than 1.0mm such as wire
and that of liquids is that,
JLab Go Air has a lower liquid rating than Boult Audio Z40
Boult Audio Z40 have a weight of 40g . We prefer a lower weight better for the reason that lighter devices are more comfortable to move with.

The Boult Audio Z40 have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass. A driver unit is basically a mini speaker that produces sound in the earbuds, its size determines the sound produced by the earbuds. JLab Go Air driver unit is 8mm in diameter,
which means that they have a smaller 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 find it difficult to produce high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they produce better quality sound. The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low audible frequencies and if it makes any changes to the signal on its way through. JLab Go Air'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 measures if and how well an audio component makes high audible frequencies and if it makes any changes to the signal on its way through.
JLab Go Air's highest frequency is at 20,000Hz, this means that
both devices generate equal treble

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. Since it uses psychoacoustic modeling, it provides 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 iPad. 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. Boult Audio Z40 have 2 microphones.
JLab Go Air microphones are 2,
equal to that of the Boult Audio Z40
. More microphones record better sound quality and enable the device to filter out noise. Boult Audio Z40 support in/on-ear detection, the sensors in the earbuds can detect when removed from your ears so that the music is paused. Boult Audio Z40 support fast charging.
