Ingress protection ratings is the level of protection offered by a casing, against solids and water. In the format of IPXX, 'X' represents a number The first value means protection against solids say dust, while the second refers to protection 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. Compared to the Boult Audio Z40, Sony LinkBuds S have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
Sony LinkBuds S 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.
Sony LinkBuds S, at 9.6g
weigh less than the Boult Audio Z40 with a difference -30.4g

The Boult Audio Z40 have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass. A driver unit is the component that makes sound in the earbuds, the unit size determines the loudness of the device. Sony LinkBuds S driver unit is 5mm in diameter,
which means that they have a smaller driver unit than that of Boult Audio Z40 by 5mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound. The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal on its way through. Sony LinkBuds S's lowest frequency is at 20Hz, this implies that
both devices make sound with equal bass
Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio component generates high audible frequencies and if it makes any changes to the signal while at it.
Sony LinkBuds S's highest frequency is at 40,000Hz, this means that
Sony LinkBuds S can generate a clearer and crispier treble than the Boult Audio Z40

older than that of Boult Audio Z40
. Newer versions provide faster data transfers. The Boult Audio Z40 have a 10meters distance connecting via Bluetooth. Sony LinkBuds S 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. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Boult Audio Z40 will work well with your MacBook.
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. The Sony LinkBuds S support AAC as well. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate.
Boult Audio Z40 have 2 microphones. The Sony LinkBuds S microphones are 6,
more than that of Boult Audio Z40 by 4
. More microphones record better sound quality and enable the earbuds 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 .
