Ingress protection ratings is the rating of protection offered by an enclosure, against dust and water. 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 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. In comparison to the Boult Audio Z40, Bose SoundSport Free have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
Boult Audio Z40 has a higher liquid rating than Bose SoundSport Free

The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it. Bose SoundSport Free's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device produces high human frequencies and if it makes any changes to the signal while at it. Bose SoundSport Free's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble

older than that of Boult Audio Z40
. Newer versions provide faster data transfers. Boult Audio Z40 have a 10meters distance to connect via Bluetooth. Bose SoundSport Free have a maximum range of 9.1meters,
less than that of Boult Audio Z40 by 0.9meters
Boult Audio Z40 support AAC, a codec used for Bluetooth audio.
It supports 24-bit audio at 250kbps. Since 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 iPad.
If you are planning 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.
