IP ratings is the rating of protection given by an enclosure, against dust and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating represents protection against solids say dust, followed by the one that refers to resistance against liquids (sweat).
Having a value of IPX4, the Technics EAH AZ80's rating is read as, the first number 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. Compared to the Technics EAH AZ80, Bowers & Wilkins PI7 have a rating of IP54 meaning that
ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety
and that of liquids is that,
they both have the same rating against liquids
The Technics EAH AZ80 have a weight of 14g . We consider a lower weight best because lighter devices are more comfortable to transport.
The Bowers & Wilkins PI7, at 50g
are heavier than the Technics EAH AZ80 by of 36g
True wireless devices have no cables linking 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 as some wireless earbuds have wires connecting the 2 earbuds together. Bowers & Wilkins PI7 also is true wireless since it doesn't have cables connecting the 2 earbuds .
Technics EAH AZ80 have sweat resistance
Technics EAH AZ80 have stereo speakers, what this means is that Technics EAH AZ80's speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.
The Bowers & Wilkins PI7 also have stereo speakers
Active noise cancellation makes use of more advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and producing -1 (inverted noise) giving 0 which results in a reduced level of noise.
The Technics EAH AZ80 have ANC allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to overcome background sounds. Bowers & Wilkins PI7 too have Active Noise Cancellation which makes either of the devices ideal for plane rides and morning commutes. The Technics EAH AZ80 and Bowers & Wilkins PI7 operate with different noise cancellation types, pick the setting that suits your travel or that enhances your relaxation time.
Technics EAH AZ80 stay tightly in place, this creates an acoustic seal that tones down background noise and also prevents the device music from leaking out at the same. Both Bowers & Wilkins PI7, and Technics EAH AZ80 have passive noise reduction which implies that both tone down ambient noise without 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, its size dictates the sound made by the device. Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which implies that they have a smaller driver unit than that of Technics EAH AZ80 by 0.8mm
, a common assumption 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 are capable of generating louder sound, but this does not imply that they deliver better quality sound.
Technics EAH AZ80's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low recognizable frequencies and if it makes any changes to the signal on its way through. Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means that
Bowers & Wilkins PI7 can produce a juicier bass than the Technics EAH AZ80
The Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response tells how well a particular audio device generates high audible frequencies and if it makes any adjustments to the signal on its way through. Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this means that
Technics EAH AZ80 can generate a clearer and crispier treble than the Bowers & Wilkins PI7
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 usually given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings. Bowers & Wilkins PI7's battery life is
less than that of Technics EAH AZ80 by 3 hours
. Each time you recharge your device, they get a little less playing time. The effect is barely noticeable at first, but over time, your wireless earbuds will have shorter listening time.
The battery life of the charging case is given by the vendor, and Technics EAH AZ80's case is said to have a full charge of 17.5 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go several times before having to recharge the case itself. Bowers & Wilkins PI7'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. Bowers & Wilkins PI7 takes 3 hours to fully charge the battery,
more than that of Technics EAH AZ80 by 1 hours
Technics EAH AZ80, the device supports wireless charging. To charge the device, you simply put down on a supported charging pad.
Bowers & Wilkins PI7 also support wireless charging, take note of the charging standard of a device. Technics EAH AZ80 have a battery level indicator, an indicator notifies you when the earbuds has a low battery. The battery indicator lights indicate the charging state of your earbuds and charging case.
Bowers & Wilkins PI7 too have a battery level indicator, charging indicators allow you determine the charging state of your device, if charged fully, or the battery is running low. The Technics EAH AZ80 use USB TYPE-C, an industry-standard connector for transmitting both data and power through a single cable. Bowers & Wilkins PI7 too support USB TYPE-C.
This USB-C plug comes along with most current laptops, phones, and tablets. The Technics EAH AZ80 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data movement between devices placed in range, using short-wavelength, ultra-high frequency radio waves. Bowers & Wilkins PI7 has a Bluetooth version of 5,
older than that of Technics EAH AZ80
. Newer versions provide faster data transfers.
Technics EAH AZ80 have a 10meters distance connecting via Bluetooth. Bowers & Wilkins PI7 have a maximum range of 10meters,
equal to that of the Technics EAH AZ80
Technics EAH AZ80 support AAC, a codec used for Bluetooth audio. It supports 24-bit audio at 250kbps.
Because it uses psychoacoustic modeling, it provides better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Technics EAH AZ80 will work well with your iPhone. If you intend on using these with Android , ensure that they also support aptX HD, LDAC, or LHDC as well.
The Bowers & Wilkins PI7 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 Technics EAH AZ80 support LDAC, a codec developed by Sony
which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbps at 32 bit/96 kHz.
It can reach a high bitrate of 990kbps, providing high-resolution audio. The Technics EAH AZ80 have 8 microphones. While the Bowers & Wilkins PI7 microphones are 6,
less than that of Technics EAH AZ80 by 2
. More microphones result in better sound quality and help the device to filter out background sounds.
Technics EAH AZ80 use a noise-canceling microphone, these microphones are intended to filter out background sounds from the earbuds' sound. The Bowers & Wilkins PI7 too have a noise-canceling type of microphone. Especially useful in noisy areas.
The Technics EAH AZ80 support ambient sound mode, which uses microphones to channel ambient noises so that they can still be heard even while wearing the earbuds
The Bowers & Wilkins PI7 support ambient sound mode as well, helpful when you want to listen to music but also be aware of what’s happening around you, say you’re having a jog but would still want to hear traffic.
