Ingress protection ratings is the rating of protection offered by an enclosure, against solids and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to 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 number of X denotes that no data available to specify a protection rating, and the second value 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. 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,
Sony LinkBuds S has a lower liquid rating than Boult Audio Z40
The Boult Audio Z40 have a weight of 40g . We prefer a lower weight better because lighter devices are more comfortable to carry.
Sony LinkBuds S, at 9.6g
weigh less than the Boult Audio Z40 with a difference -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 an important distinction since wireless earbuds have wires connecting the 2 earbuds together. Sony LinkBuds S also is true wireless because it has no wires linking the pair of earbuds .
The Boult Audio Z40 come with wingtips, these are commonly used for earbuds for workouts and come as an optional add-on to the separate silicone ear tip for a better fit.
Boult Audio Z40 are resistant to sweat
Sony LinkBuds S's resistance to sweat makes both devices ideal for use while doing sports such as long-distance running, marathons, cardio sweat workouts , etc
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 separate channels on both left and right sides, creating a richer sound and a better listening experience. Both Sony LinkBuds S and Boult Audio Z40 have stereo speakers
Boult Audio Z40 sit tightly in place, this creates a sound covering that reduces your environment noise well as preventing the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction this implies that both reduce 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, therefor producing better bass. A driver unit is the component that makes sound in the device, its 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
, 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 indicate that they produce better quality sound. The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low audible frequencies 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 can produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device makes high audible 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 generate 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 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 earbuds, they get a little less playing time. The effect is not noticeable at first, but over a few years, your wireless earbuds will have shorter listening time. This is given by the vendor, and the Boult Audio Z40's case has a full charge of 50 hours.
A charging case with a longer battery life 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 recommended to fully charge the battery before using the earbuds when they have been in storage for long periods.
Sony LinkBuds S takes 2 hours to fully charge the battery,
more than that of Boult Audio Z40 by 0.5 hours
The Boult Audio Z40 use USB TYPE-C, a standard connector for transmitting both data and power in a single cable. Sony LinkBuds S too use USB TYPE-C. This USB-C plug is part and parcel of most current electronics.
The Boult Audio Z40 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data movement between devices placed in range, 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.
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 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. Sony LinkBuds S microphones are 6,
more than that of Boult Audio Z40 by 4
. More microphones result in better sound quality and enable the earbuds to filter out noise.
Boult Audio Z40 have in/on-ear detection, the sensors in the earbuds can detect when they are removed from your ears .
