A breakdown of the review per specifications

Design

Ingress Protection (Ip) Rating

Audio Technica ATH TWX9 IPX4
Bowers & Wilkins PI7 IP54

IP ratings is the rating of protection offered by an enclosure, against solids and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, while the second refers to resistance against liquids (sweat).

Scoring IPX4, the Audio Technica ATH TWX9'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.

Compared 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

Weight

Sound Quality

Has Active Noise Cancellation (Noise Control)

Audio Technica ATH TWX9
Bowers & Wilkins PI7

ANC makes use of more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) to make 0 which results in a reduced level of noise.

Audio Technica ATH TWX9 have ANC enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to overcome background sounds.

Bowers & Wilkins PI7 too have Active Noise Cancellation making both earbuds ideal for plane rides and rush hour travels. Each work with different noise cancellation types, pick the setting that suits your commute or that suites your relaxation time.
