IP ratings refer to the level of protection offered by an enclosure, against dust and liquids. In the format of IPXX, 'X' represents a number The first value means protection against solids such as dust, while the second refers to resistance against liquids (water).
Scoring IPX5, the Boult Audio Z40's rating is read as, the first number 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, 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,
Boult Audio Z40 has a higher liquid rating than Sony LinkBuds S
Boult Audio Z40 have a weight of 40g . We take in account a lower weight better for the reason that lighter devices are easier to transport.
Sony LinkBuds S, at 9.6g
are lighter than the Boult Audio Z40 with a difference -30.4g

Boult Audio Z40 driver unit is 10mm in diameter, bigger drivers are more powerful, and can produce better bass. A driver unit is the component that produces sound in the earbuds, its size dictates the loudness of the device. Sony LinkBuds S driver unit is 5mm in diameter,
which implies that they have a smaller driver unit than that of Boult Audio Z40 by 5mm
, a common assumption 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 deliver better quality sound. The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low recognizable frequencies and if it alters the signal on its way through. Sony LinkBuds S's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio device produces high recognizable frequencies and if it makes any changes to the signal while at it.
Sony LinkBuds S's highest frequency is at 40,000Hz, this implies that
Sony LinkBuds S generate a clearer and crispier treble than the Boult Audio Z40
The Boult Audio Z40's battery life is 10 hours, these last longer than 5 hours of listening which is considered average before recharge. A device's battery life is usually given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings. Sony LinkBuds S's battery life is
less than that of Boult Audio Z40 by 4 hours
. Every time you recharge your device, they get a little less playing time.
The effect is barely noticeable at first, but over time, your wireless earbuds will have shorter listening time. This is given by the manufacturer, and the Boult Audio Z40's case has a charge of 50 hours. A charging case with more battery hours enables you to recharge your earbuds on the go several times before having to recharge the case itself.
Sony LinkBuds S's charging case has a battery life of 14 hours,
less than that of Boult Audio Z40 by 36 hours

Sony LinkBuds S has a Bluetooth version of 5.2,
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. Since it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.

If you are planning on using these with Android , 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.
The Boult Audio Z40 have 2 microphones. Sony LinkBuds S microphones are 6,
more than that of Boult Audio Z40 by 4
. More microphones record better sound quality and enable the device to filter out background sounds. Boult Audio Z40 have in/on-ear detection, the sensors in the earbuds can detect when they are removed from your ears so that the music is paused.
