Ingress protection ratings refer to the level of protection offered by an enclosure, against solids and liquids. The letters 'IP' are followed by two values The first value means protection against solids such as dust, while the second refers to resistance against liquids (water).
Scoring IPX4, the Bose QuietComfort Earbuds 2's rating is read as, the first number of X denotes 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. In comparison to the Bose QuietComfort Earbuds 2, 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 Bose QuietComfort Earbuds 2 have a weight of 12.5g . We prefer a lower weight better for the reason that lighter devices are more comfortable to move with.
Bowers & Wilkins PI7, at 50g
weigh more than the Bose QuietComfort Earbuds 2 by of 37.5g
True wireless devices have no wires linking any part of the device together, Bose QuietComfort Earbuds 2 are true wireless for this matter since they don't have cables. This is an important distinction since wireless earbuds have wires connecting the pair of earbuds .
Bowers & Wilkins PI7 also is true wireless since it has no cables connecting the pair of earbuds together. Bose QuietComfort Earbuds 2 have wingtips, these are reserved for earbuds for workouts and are usually an optional add-on to each silicone ear tip for a better fit.
Bose QuietComfort Earbuds 2 are resistant to sweat
Bose QuietComfort Earbuds 2 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. Both Bowers & Wilkins PI7 and Bose QuietComfort Earbuds 2 have stereo speakers
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it listens to the sound pattern of incoming noise and then generates a mirror signal to counter it.
Simply put, it's like taking +1 (noise) and adding -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
Bose QuietComfort Earbuds 2 have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background noise. The Bowers & Wilkins PI7 too have Active Noise Cancellation which makes both earbuds ideal for flights and morning travels.
Each work with different noise cancellation types, pick the setting that you prefer for commute or that enhances your relaxation time. Bose QuietComfort Earbuds 2 sit tightly in place, creating a sound covering that tones down background sounds well as preventing the device sound from leaking out .
Both of these devices have passive noise reduction which implies that both limit ambient noise without using technology to cancel it out. Bose QuietComfort Earbuds 2 have a unit size of 9.3mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that produces sound in the earbuds, its size corellates with the loudness of the earbuds. Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which means that they have a smaller driver unit than that of Bose QuietComfort Earbuds 2 by 0.1mm
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, low-frequency response inidcates how well an 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 implies that
Bowers & Wilkins PI7 can produce a juicier bass than the Bose QuietComfort Earbuds 2
The Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, high-frequency response tells how well an audio component generates high recognizable frequencies and if it makes any changes to the signal on its way through. Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that
both devices can generate equal treble
The Bose QuietComfort Earbuds 2's battery life is 6 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. Bowers & Wilkins PI7's battery life is
less than that of Bose QuietComfort Earbuds 2 by 1.5 hours
. Each time you recharge your earbuds, they get a little less listening 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 manufacturer, and the Bose QuietComfort Earbuds 2's case is said to have a full charge of 18 hours. A charging case with more battery hours allows you to recharge your earbuds on the go several times before recharging the case itself. Bowers & Wilkins PI7's charging case has a battery life of 18 hours,
equal to that of the Bose QuietComfort Earbuds 2
It requires 2 hours to fully charge the Bose QuietComfort Earbuds 2's battery.
It is highly adivsable to fully charge 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 Bose QuietComfort Earbuds 2 by 1 hours
The Bose QuietComfort Earbuds 2 have a battery level indicator, an indicator shows you when the earbuds has a low battery. Its lights indicate the charging state of your device and case.
Bowers & Wilkins PI7 too have a battery level indicator, these enable you determine the charging state of your device, whether fully charged, or the battery is running low. Bose QuietComfort Earbuds 2 support USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable. Bowers & Wilkins PI7 too have USB TYPE-C.
This USB-C plug is part and parcel of most current electronics. The Bose QuietComfort Earbuds 2 have Bluetooth version of 5.3, Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Bowers & Wilkins PI7 has a Bluetooth version of 5,
older than that of Bose QuietComfort Earbuds 2
. Newer versions provide faster data transfers.
Bose QuietComfort Earbuds 2 have a 10meters distance connecting via Bluetooth. Bowers & Wilkins PI7 have a maximum range of 10meters,
equal to that of the Bose QuietComfort Earbuds 2
Bose QuietComfort Earbuds 2 support AAC, a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps.
Since it uses psychoacoustic modeling, it can provide better results than other codecs at the same bit rate.
Being the highest quality codec that any Bluetooth-supporting Apple product supports, the Bose QuietComfort Earbuds 2 will work well with your iPad. If you are planning 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. Bose QuietComfort Earbuds 2 support APTX Adaptive, an audio codec for Bluetooth devices that are developed by Qualcomm.
It has a variable bit rate (between 279kbps and 420kbps).
Bowers & Wilkins PI7 support APTX Adaptive as well which means both can adjust the bit rate for different scenarios, such as reducing interference from other devices. Bose QuietComfort Earbuds 2 have 8 microphones. While the Bowers & Wilkins PI7 microphones are 6,
less than that of Bose QuietComfort Earbuds 2 by 2
. More microphones result in better sound quality and enable the earbuds to filter out noise.
Bose QuietComfort Earbuds 2 use a noise-canceling type of microphone, these microphones are designed to reduce noise from the desired sound. The Bowers & Wilkins PI7 too use a noise-canceling microphone. This is useful in noisy environments.
