The Bowers and Wilkins Pi7 S2 offers wireless convenience, superior sound quality, and active noise cancelling, making them suitable for immersive music listening, especially during air travel, but they have a shorter battery life. The KZ ZSN Pro (with Mic), while wired and lacking noise cancellation, has a durable build and better mic quality, and it excels in gaming due to lower latency; these are much more affordable. If budget is a concern and you prioritize gaming or need a mic for calls, go for the KZ. For a premium listening experience with wireless freedom, choose the Bowers and Wilkins, but they will cost more. Give Feedback

Engadget

Billy Steele | March 2023
"While the overall sound quality is great, these earbuds fall short in terms of battery life, customization and ANC performance. Bowers & Wilkins’ ability to consistently deliver pristine sound isn’t enough to make up for what the Pi7 S2 lacks, which is unfortunately quite a bit."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
