IP ratings refer to the level of protection given by an enclosure, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating means protection against solids say dust, followed by the one that refers to protection against liquids (sweat).
Having a value of IPX4, the Technics EAH AZ80's rating is read as, the first value of X denotes that no data available to specify a protection rating, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. In comparison to the Technics EAH AZ80, Bose QuietComfort 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 take in account a lower weight better because lighter devices are easier to move with.
The Bose QuietComfort 2, at 12.5g
weigh less than the Technics EAH AZ80 with a difference -1.5g
True wireless devices have no cables connecting any part of the device together, Technics EAH AZ80 are true wireless for this case since they have no cables. This is a major distinction since wireless earbuds have wires connecting the two earbuds .
Bose QuietComfort 2 also is true wireless because it has no cables linking the two earbuds .
Technics EAH AZ80 are resistant to sweat
Bose QuietComfort 2's resistance to sweat makes both devices good for use during long-distance running, marathons, training in workout bodysuits, etc
Technics EAH AZ80 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 Bose QuietComfort 2 also have stereo speakers
ANC utilises advanced technology to reduce unwanted ambient sounds.
How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make zero which results in a reduced level of noise.
The Technics EAH AZ80 have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the device volume to outcompete background noise.
The Bose QuietComfort 2 too have Active Noise Cancellation making both earbuds ideal for flights and morning travels. Each operate with different noise cancellation modes, pick the setting that you prefer for commute or that enhances your relaxation time. The Technics EAH AZ80 stay well in place, this creates a sound seal that tones down your environment sounds while preventing the device music from leaking out .

Technics EAH AZ80 have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass. A driver unit is the component that produces sound in the device, its size dictates the sound produced by the device. Bose QuietComfort 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
, 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 indicate 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 frequencies that can be heard, and if it makes any changes to the signal while at it. Bose QuietComfort 2's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
The Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response measures if and how well an audio component produces high audible frequencies and if it makes any adjustments to the signal on its way through.
Bose QuietComfort 2's highest frequency is at 20,000Hz, this means that
Technics EAH AZ80 can produce a clearer and crispier treble than the Bose QuietComfort 2
The Technics EAH AZ80's battery life is 7.5 hours, these last longer than 5 hours of listening which is considered average for a single charge. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chargings. Bose QuietComfort 2's battery life is
less than that of Technics EAH AZ80 by 1.5 hours
. Every time you recharge your device, they get a little less listening time.
The effect is not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to. This is given by the manufacturer, and Technics EAH AZ80's case has a full charge of 17.5 hours. A charging case with more battery hours enables you to recharge your earbuds on the go many times before having to recharge the case itself.
Bose QuietComfort 2's charging case has a battery life of 18 hours,
more than that of Technics EAH AZ80 by 0.5 hours
It requires 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. Bose QuietComfort 2 takes 2 hours to fully charge the battery,
equal to that of the Technics EAH AZ80
