Ingress protection ratings refer to the level of protection given 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, followed by the one that refers to protection against liquids (water).
Scoring IPX4, the Technics EAH AZ80's rating for solids indicates that no data available to specify a protection rating, and the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Compared to the Technics EAH AZ80, Bose QuietComfort Earbuds 2 have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
they both have the same rating against liquids
Technics EAH AZ80 have a weight of 14g . We consider a lower weight better for the reason that lighter devices are easier to carry.
Bose QuietComfort Earbuds 2, at 12.5g
weigh less than the Technics EAH AZ80 by -1.5g
True wireless devices have no cables connecting any part of the device together, Technics EAH AZ80 are true wireless for this matter since they don't have cables. This is an important distinction since wireless earbuds have wires connecting the 2 earbuds together. Bose QuietComfort Earbuds 2 also is true wireless because it doesn't have wires linking the two earbuds .
Technics EAH AZ80 have sweat resistance
Bose QuietComfort Earbuds 2's resistance to sweat makes both devices ideal for use while doing sports such as long-distance running, marathons, cardio sweat workouts , etc
Technics EAH AZ80 have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.
The Bose QuietComfort Earbuds 2 also have stereo speakers
ANC makes use of advanced technology to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (inverted noise) giving 0 resulting in a reduced level of noise.
The Technics EAH AZ80 have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to overcome background sounds. The Bose QuietComfort Earbuds 2 too have ANC which makes both devices ideal for plane rides and morning commutes. Each operate with different noise cancellation types, pick the setting that you prefer for commute or that suites your relaxation time.
The Technics EAH AZ80 sit tightly in place, creating an acoustic covering that reduces background noise and also prevents the device sound from leaking out .
Both of these devices have passive noise reduction which means that they reduce ambient noise instead of actively using ANC to cancel it out. Technics EAH AZ80 driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass. The driver unit is the component that makes sound in the device, the unit size determines the loudness of the earbuds.
Bose QuietComfort Earbuds 2 driver unit is 9.3mm in diameter,
which implies that they have a smaller driver unit than that of Technics EAH AZ80 by 0.7mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound. The Technics EAH AZ80's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device produces low audible frequencies and if it alters the signal while at it.
Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response shows how well a particular audio device generates high human frequencies and if it makes any adjustments to the signal on its way through. Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, this implies that
Technics EAH AZ80 produce a clearer and crispier treble than the Bose QuietComfort Earbuds 2
Technics EAH AZ80's battery life is 7.5 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 have to charge the device less often.
Bose QuietComfort Earbuds 2's battery life is
less than that of Technics EAH AZ80 by 1.5 hours
. Every time you recharge your earbuds, they get a little less listening time. The effect is not 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 manufacturer, and Technics EAH AZ80's case is said to have a full charge of 17.5 hours.
A charging case with more battery hours allows you to recharge your earbuds on the go many times before recharging the case itself. Bose QuietComfort Earbuds 2's charging case has a battery life of 18 hours,
more than that of Technics EAH AZ80 by 0.5 hours
It takes 2 hours to fully charge the Technics EAH AZ80's battery. It is recommended to charge fully the battery before using the earbuds for the first time.
