Ingress protection ratings refer to the level of protection given by an enclosure, against solids and water. In the format of IPXX, 'X' represents a number The first value of the IP rating represents protection against solids say dust, while the second refers to resistance 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, 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,
Boult Audio Z40 has a higher liquid rating than JLab Go Air
The Boult Audio Z40 have a weight of 40g . We consider a lower weight better because lighter devices are more comfortable to move with.
JLab Go Air, at 10g
weigh less than the Boult Audio Z40 by -30g
True wireless devices have no cables connecting any part of the device together, Boult Audio Z40 are true wireless for this matter since they have no cables. This is an important difference since wireless earbuds have wires connecting the 2 earbuds together. JLab Go Air also is true wireless since it has no cables connecting the pair of earbuds together.

Both JLab Go Air and Boult Audio Z40 have stereo speakers
The Boult Audio Z40 sit tightly in place, creating a sound covering that tones down background noise and also prevents the device sound from leaking out at the same. Both JLab Go Air, and Boult Audio Z40 have passive noise reduction this implies that they limit ambient noise instead of actively using technology to cancel it out. Boult Audio Z40 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the earbuds, its size corellates with the loudness of 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 it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they deliver 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 produces low recognizable frequencies and if it makes any changes to the signal while at it. JLab Go Air's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device generates high audible frequencies and if it changes to the signal while at it. JLab Go Air'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.

Boult Audio Z40 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data movement between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves.
JLab Go Air has a Bluetooth version of 5,
older than that of Boult Audio Z40
. Newer versions provide faster data transfers. Boult Audio Z40 have a 10meters distance to connect via Bluetooth. JLab Go Air 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. 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 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. Boult Audio Z40 have 2 microphones. The JLab Go Air microphones are 2,
equal to that of the Boult Audio Z40
. More microphones record better sound quality and enable the earbuds to filter out noise.
