IP ratings is the level of protection given by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, while the second refers to protection against liquids (water).
Scoring IP54, the Bowers & Wilkins PI7's rating for solids indicates 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 of liquids 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 Bowers & Wilkins PI7, Anker Soundcore Liberty 3 Pro have a rating of IPX4 meaning that
no data available to specify a protection rating
and that of liquids is that,
they both have the same rating against liquids
Bowers & Wilkins PI7 have a weight of 50g . We consider a lower weight better for the reason that lighter devices are more comfortable to transport.
The Anker Soundcore Liberty 3 Pro, at 12g
are lighter than the Bowers & Wilkins PI7 by -38g
True wireless devices have no cables linking any part of the device together, Bowers & Wilkins PI7 are true wireless for this case since they have no cables. This is an important distinction as some wireless earbuds have wires connecting the 2 earbuds .
Anker Soundcore Liberty 3 Pro also is true wireless because it doesn't have wires connecting the two earbuds .
Bowers & Wilkins PI7 have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience. Both Anker Soundcore Liberty 3 Pro and Bowers & Wilkins PI7 have stereo speakers
Active noise cancellation utilises more advanced technology to reduce ambient sounds.
ANC works when, 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 having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
The Bowers & Wilkins PI7 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to outcompete background sounds.
Anker Soundcore Liberty 3 Pro too have ANC which makes both earbuds ideal for flights and morning commutes. The Bowers & Wilkins PI7 and Anker Soundcore Liberty 3 Pro operate with different noise cancellation modes, pick the mode that you prefer for travel or that enhances your chill time. Bowers & Wilkins PI7 sit well in place, creating a sound covering that reduces your environment noise and also prevents the device sound from leaking out .
Both Anker Soundcore Liberty 3 Pro, and Bowers & Wilkins PI7 have passive noise reduction which implies that they tone down ambient noise instead of actively using technology to cancel it out.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, bigger drivers are more powerful, and can produce better bass. A driver unit is the component that produces sound in the earbuds, the unit size determines the loudness of the device. Anker Soundcore Liberty 3 Pro driver unit is 10.6mm in diameter,
making them have a larger driver unit than that of Bowers & Wilkins PI7 by 1.4mm
, 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 can generate louder sound, but this does not imply that they deliver better quality sound. Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it alters the signal on its way through. Anker Soundcore Liberty 3 Pro's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 make sound with a juicier bass than the Anker Soundcore Liberty 3 Pro
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio component makes high audible frequencies and if it makes any adjustments to the signal while at it.
Anker Soundcore Liberty 3 Pro's highest frequency is at 40,000Hz, this implies that
Anker Soundcore Liberty 3 Pro produce a clearer and crispier treble than the Bowers & Wilkins PI7
The Bowers & Wilkins PI7's battery life is 4.5 hours, these last less than 5 hours of listening which is considered average before recharge. A device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and have to charge the device less often. Anker Soundcore Liberty 3 Pro's battery life is
more than that of Bowers & Wilkins PI7 by 3.5 hours
. Every time you recharge your earbuds, they get a little less listening time.
The effect is not 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 Bowers & Wilkins PI7's case is said to have a full charge of 18 hours. A charging case with more battery hours enables you to recharge your earbuds on the go multiple times before having to recharge the case itself.
Anker Soundcore Liberty 3 Pro's charging case has a battery life of 24 hours,
more than that of Bowers & Wilkins PI7 by 6 hours
It requires 3 hours to fully charge the Bowers & Wilkins PI7's battery. It is highly adivsable to charge fully the battery before using the earbuds for the first time. Anker Soundcore Liberty 3 Pro takes 2 hours to fully charge the battery,
less than that of Bowers & Wilkins PI7 by 1 hours

Bowers & Wilkins PI7 have a battery level indicator, an indicator notifies you when the device has a low battery.
Its lights indicate the charging state of your device and charging case. Anker Soundcore Liberty 3 Pro too have a battery level indicator, charging indicators enable you to tell the charging state of your earbuds, if charged fully, or having a low battery. The Bowers & Wilkins PI7 have USB TYPE-C, an industry-standard connector for transmitting both data and power in a single cable.
Anker Soundcore Liberty 3 Pro too have USB TYPE-C. This USB-C plug comes along with most current electronics. The Bowers & Wilkins PI7 have Bluetooth version of 5, Bluetooth is a wireless technology standard that allows data transfers between devices placed in range, using short-wavelength, ultra-high frequency radio waves.
Anker Soundcore Liberty 3 Pro has a Bluetooth version of 5.2,
newer than that of Bowers & Wilkins PI7
. Newer versions provide faster data transfers. The Bowers & Wilkins PI7 have a 10meters distance connecting via Bluetooth. Anker Soundcore Liberty 3 Pro have a maximum range of 10meters,
equal to that of the Bowers & Wilkins PI7
Bowers & Wilkins PI7 support AAC, a codec that is used for Bluetooth audio.
It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at the same bit rate.
Since its the highest quality codec that any Bluetooth-supporting Apple product supports, the Bowers & Wilkins PI7 will work fine with your iPad.
