which implies that they have a smaller driver unit than that of Boult Audio Z40 by 4.2mm
, many people have a misconception 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 indicate that they produce better quality sound. Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it alters the signal while at it. Sony WF C500's lowest frequency is at 20Hz, this means that
both devices produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component produces high human frequencies and if it makes any adjustments to the signal on its way through.
Sony WF C500's highest frequency is at 20,000Hz, this implies that
both devices can generate equal treble
Boult Audio Z40's battery life is 10 hours, these last longer than 5 hours of listening which is considered average for a single charge.

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 WF C500 have a maximum range of 9meters,
less than that of Boult Audio Z40 by 1meters
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 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 WF C500 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 WF C500 microphones are 2,
equal to that of the Boult Audio Z40
. More microphones result in better sound quality and enable 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 .
