Ingress protection ratings is the level of protection given by a casing, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating refers to protection against solids such as dust, while the second refers to protection 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, JBL Live Free 2 have a rating of IPX5 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
they both have the same rating against liquids
The Boult Audio Z40 have a weight of 40g . We prefer a lower weight better for the reason that lighter devices are easier to transport.
The JBL Live Free 2, at 9.8g
are lighter than the Boult Audio Z40 by -30.2g
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 wires.

Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low audible frequencies and if it alters the signal on its way through.
JBL Live Free 2's lowest frequency is at 20Hz, this implies 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 a particular audio component generates high audible frequencies and if it makes any changes to the signal on its way through. JBL Live Free 2's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble

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. Since it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Since its 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.
