IP ratings is the rank of protection offered by a casing, against solids and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, followed by the one that refers to resistance against liquids (sweat).
Having a value of IPX5, the Boult Audio Z40's rating is read as, the first value 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, JBL Reflect Aero TWS have a rating of IP68 meaning that
they are completely dust proof
and that of liquids is that,
JBL Reflect Aero TWS has a higher liquid rating than Boult Audio Z40
Boult Audio Z40 have a weight of 40g . We take in account a lower weight better because lighter devices are more comfortable to transport.
JBL Reflect Aero TWS, at 13g
weigh less than the Boult Audio Z40 by -27g
True wireless devices have no wires linking any part of the device together, Boult Audio Z40 are true wireless for this matter since they don't have wires. This is a major difference since wireless earbuds have cables linking the pair of earbuds together. JBL Reflect Aero TWS also is true wireless because it has no cables linking the pair of 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 more secure fit.
JBL Reflect Aero TWS too have wingtips, by resting against the triangular fossa and form a secure fit to combat vigorous movement, wingtips are best suited for sports and other physical activities. When used rightly, they secure the earbuds from falling off. Boult Audio Z40 have sweat resistance
JBL Reflect Aero TWS's resistance to sweat makes both devices ideal for use during long-distance running, marathons, cardio sweat workouts , etc
The Boult Audio Z40 are both dustproof and water-resistant.
JBL Reflect Aero TWS too are dustproof and water-resistant, which means that they can prevent water and dust from entering the interior of the devices keeping the interior components safe
Boult Audio Z40 have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience. The JBL Reflect Aero TWS also have stereo speakers
Boult Audio Z40 stay well in place, this creates an acoustic covering that tones down background sounds and also prevents the device sound from leaking out at the same. Both of these devices have passive noise reduction which means that they tone down ambient noise without using technology to cancel it out.
Boult Audio Z40 have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass. The driver unit is basically a mini speaker that produces sound in the device, the unit size determines the sound made by the device. JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
which implies that they have a smaller driver unit than that of Boult Audio Z40 by 3.2mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not imply that they deliver 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 frequencies that can be heard, and if it alters the signal while at it. JBL Reflect Aero TWS's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio component makes high audible frequencies and if it changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this implies that
both devices produce equal treble
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 commonly given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings. JBL Reflect Aero TWS's battery life is
less than that of Boult Audio Z40 by 2 hours
. Each time you recharge your earbuds, they get a little less listening time.
The effect is barely noticeable at first, but over a few years, your wireless earbuds will have shorter listening time. The battery life of the charging case is given by the vendor, and Boult Audio Z40's case is said to have a charge of 50 hours. A charging case with more battery hours enables you to recharge your earbuds on the go several times before recharging the case itself.
JBL Reflect Aero TWS's charging case has a battery life of 16 hours,
less than that of Boult Audio Z40 by 34 hours
It requires 1.5 hours to fully charge the Boult Audio Z40's battery. It is highly adivsable to charge fully the battery before using the earbuds for the first time. JBL Reflect Aero TWS takes 1.5 hours to fully charge the battery,
equal to that of the Boult Audio Z40

JBL Reflect Aero TWS too use USB TYPE-C. This USB-C plug comes along with most current laptops, phones, and tablets. Boult Audio Z40 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that enables data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves.
JBL Reflect Aero TWS has a Bluetooth version of 5.2,
older than that of Boult Audio Z40
. Newer versions provide faster data transfers. Boult Audio Z40 have a 10meters distance to connect via Bluetooth. JBL Reflect Aero TWS 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 intend on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well. Boult Audio Z40 have 2 microphones. JBL Reflect Aero TWS microphones are 6,
more than that of Boult Audio Z40 by 4
. More microphones result in better sound quality and help the device to filter out background sounds.
