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 yeah, 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 frequencies that can be heard, 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 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 generates high human frequencies and if it adjustments to the signal while at it. Sony LinkBuds S's highest frequency is at 40,000Hz, this means that
Sony LinkBuds S can produce a clearer and crispier treble than the Boult Audio Z40

older than that of Boult Audio Z40
. Newer versions provide faster data transfers.
Boult Audio Z40 have a 10meters distance to connect 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.

Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Boult Audio Z40 will work well with your iPhone. If you intend 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. The 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 result in better sound quality and help the earbuds 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 .
