IP ratings refer to the level of protection offered by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value means protection against solids say dust, while the second refers to protection against liquids (water).
Scoring IPX4, the Audio Technica ATH TWX9'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 Audio Technica ATH TWX9, 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
Audio Technica ATH TWX9 have a weight of 10.8g . We consider a lower weight best because lighter devices are more comfortable to move with.
The Bowers & Wilkins PI7, at 50g are heavier than the Audio Technica ATH TWX9 by of 39.2g
For a device to be true wireless it should have no wires connecting any part of the device together, Audio Technica ATH TWX9 are true wireless for this case since they have no wires. This is a major distinction since wireless earbuds have wires linking the pair of earbuds .
Bowers & Wilkins PI7 also is true wireless since it has no cables connecting the 2 earbuds .
Audio Technica ATH TWX9 are resistant to sweat
Audio Technica ATH TWX9 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.
The Bowers & Wilkins PI7 also have stereo speakers
ANC utilises more advanced technology to actively counter noise. ANC works when, it studies the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and producing -1 (inverted noise) giving 0 hence "diluting" the noise.
The Audio Technica ATH TWX9 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background sounds.
The Bowers & Wilkins PI7 too have ANC which makes both devices ideal for flights and rush hour commutes. The Audio Technica ATH TWX9 and Bowers & Wilkins PI7 work with different noise cancellation modes, pick the noise cancellation type that suits your commute or that enhances your relaxation time.
The Audio Technica ATH TWX9 stay well in place, this creates a sound seal that reduces background sounds and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction which means that both limit ambient noise instead of actively using technology to cancel it out.
The Audio Technica ATH TWX9 have a unit size of 5.8mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, its size dictates the loudness of the device.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, making them have a larger driver unit than that of Audio Technica ATH TWX9 by 3.4mm , many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers can generate louder sound, but this does not indicate that they deliver better quality sound.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low audible frequencies and if it alters the signal on its way through.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means that Bowers & Wilkins PI7 produce a juicier bass than the Audio Technica ATH TWX9
The Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response indicates how well an audio device generates high recognizable frequencies and if it makes any adjustments to the signal while at it.
Bowers & Wilkins PI7's highest frequency is at 20000Hz, this implies that Audio Technica ATH TWX9 can produce a clearer and crispier treble than the Bowers & Wilkins PI7
The sound pressure level, is the pressure level of sound, measured in decibels, dB, Audio Technica ATH TWX9's measurement is 102dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Audio Technica ATH TWX9's battery life is 6 hours, a device's battery life is commonly given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chanrgings.
Bowers & Wilkins PI7's battery life is less than that of Audio Technica ATH TWX9 by 1.5 hours . Each time you recharge your earbuds, they get a little less playing time. The effect is barely noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to.
This is given by the vendor, and the Audio Technica ATH TWX9's case is said to have a charge of 18.5 hours. A charging case with more battery hours enables 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, less than that of Audio Technica ATH TWX9 by 0.5 hours
It takes 2.5 hours to fully charge the Audio Technica ATH TWX9's battery. It is highly adivsable to charge fully the battery before using the earbuds when they have been unused for long periods.
Bowers & Wilkins PI7 takes 3 hours to fully charge the battery, more than that of Audio Technica ATH TWX9 by 0.5 hours
The Bowers & Wilkins PI7, the device supports wireless charging. To charge the earbuds, you simply put down on a compatible charging pad.

The Audio Technica ATH TWX9 have 4 microphones.
While the Bowers & Wilkins PI7 microphones are 6, more than that of Audio Technica ATH TWX9 by 2 . More microphones record better sound quality and enable the device to filter out noise.
Audio Technica ATH TWX9 use a noise-canceling microphone, these microphones are made to filter out background sounds from the desired sound.
The Bowers & Wilkins PI7 too have a noise-canceling type of microphone. This is useful in noisy environments.
The Audio Technica ATH TWX9 microphone sensitivity is measured at -38dBV/Pa. The extent of the analog or digital output signal from the microphone with its input stimulus is a calculation of its sensitivity. It's the 'loudness' of the sound that the earbud microphone can recognize.
Audio Technica ATH TWX9's highest mic frequency is 16000Hz, high frequencies are best for recording treble. The highest mic frequency of a microphone is defined as its upper limiting frequency.
The Audio Technica ATH TWX9's lowest mic frequency is 100Hz, low frequencies are better for picking up bass. The lowest mic frequency of a microphone is defined as its lower limiting frequency.
The Audio Technica ATH TWX9 support ambient sound mode, which uses microphones to pass through ambient sound so that they can still be heard even when wearing the earbuds
