A breakdown of the review per specifications

Design

Ingress Protection (Ip) Rating

Sennheiser CX 500BT ipX4
Bowers & Wilkins PI7 ip54

Ingress protection ratings refer to the level of protection given by an enclosure, against solids and liquids. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, while the second refers to resistance against liquids (sweat).

Having a value of IPX4, the Sennheiser CX 500BT's rating is read as, the first value of X denotes that no data available to specify a protection rating, 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 Sennheiser CX 500BT, 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

Sound Quality

Has Active Noise Cancellation (Noise Control)

Sennheiser CX 500BT
Bowers & Wilkins PI7

ANC utilises more advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like taking +1 (noise) and adding -1 (inverted noise) giving zero thus "diluting" the noise.

The Sennheiser CX 500BT have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise.

The Bowers & Wilkins PI7 too have Active Noise Cancellation making either of the devices ideal for plane rides and morning commutes. Each work with different noise cancellation settings, pick the noise cancellation type that you prefer for commute or that suites your relaxation time.
