IP ratings is the level of protection offered by an enclosure, against dust and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, while the second refers to protection against liquids (sweat).
Scoring IPX5, the Boult Audio Z40's rating for solids indicates that no data available to specify a protection rating, and the second number 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. 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,
Boult Audio Z40 has a higher liquid rating than Sony LinkBuds S
The Boult Audio Z40 have a weight of 40g . We prefer a lower weight better for the reason that lighter devices are easier to carry.
Sony LinkBuds S, at 9.6g
are lighter than the Boult Audio Z40 by -30.4g
For a device to be true wireless it should have no cables linking any part of the device together, Boult Audio Z40 are true wireless for this matter since they have no wires. This is a major distinction as some wireless earbuds have cables linking the 2 earbuds .
Sony LinkBuds S also is true wireless since it doesn't have cables connecting the two earbuds .
The Boult Audio Z40 come with wingtips, these are commonly used for workout earbuds and come as an optional add-on to the separate silicone ear tip for a better fit. Boult Audio Z40 have sweat resistance
Sony LinkBuds S's resistance to sweat makes both devices good for use during long-distance running, marathons, cardio sweat workouts , etc
The Boult Audio Z40 are both dustproof and water-resistant.
Boult Audio Z40 have stereo speakers, what this means is that Boult Audio Z40's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. The Sony LinkBuds S also have stereo speakers
Boult Audio Z40 stay well in place, this creates a sound seal that reduces background noise while preventing the device music from leaking out .
Both of these devices have passive noise reduction this means that they limit ambient noise instead of actively using ANC to cancel it out. The Boult Audio Z40 have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is the component that produces sound in the device, its size determines the sound produced by 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
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not imply that they produce better quality sound.
Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low audible frequencies and if it makes any changes to the signal while at it. Sony LinkBuds S's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component makes high recognizable frequencies and if it adjustments to the signal while at it. Sony LinkBuds S's highest frequency is at 40,000Hz, this implies that
Sony LinkBuds S can produce a clearer and crispier treble than the Boult Audio Z40
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 commonly given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often. 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.
The battery life of the charging case is given by the vendor, and the Boult Audio Z40's case has a full charge of 50 hours. A charging case with more battery hours allows you to recharge your earbuds on the go many times before recharging 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
It takes 1.5 hours to fully charge the Boult Audio Z40's battery.
It is highly adivsable to fully charge the battery before using the earbuds for the first time. Sony LinkBuds S takes 2 hours to fully charge the battery,
more than that of Boult Audio Z40 by 0.5 hours
Boult Audio Z40 have USB TYPE-C, a standard connector for transmitting both data and power through a single cable. Sony LinkBuds S too use USB TYPE-C.
This USB-C plug is part and parcel of most current laptops, phones, and tablets. 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. 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 that is used for Bluetooth audio. It supports 24-bit audio at 250kbps.
Because it uses psychoacoustic modeling, it provides 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 fine with your iPhone. 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.
While the Sony LinkBuds S microphones are 6,
more than that of Boult Audio Z40 by 4
. More microphones record better sound quality and help the device to filter out background sounds. The Boult Audio Z40 support in/on-ear detection, the sensors in the earbuds can detect when they are removed from your ears .
Sony LinkBuds S too support in/on-ear detection, automatically pauses your music, or audiobook when you remove earbuds from your ears saving battery life. The Boult Audio Z40 support fast charging.
Usually, technologies like Qualcomm’s Quick Charge, are used to reduce the time it takes to fully charge a device. Sony LinkBuds S too support fast charging. This kind is similar to regular charging, just that the battery is filling up much faster.
