If you prioritize wireless convenience and active noise cancelling, the Bowers and Wilkins Pi7 S2 would suit you, as they also support high-quality Bluetooth codecs, have a good sound quality and are sweatproof, making them versatile for various situations including exercise. However, the Sennheiser IE600, though wired and without noise cancellation, offers superior sound and build quality, which may appeal if you are an audiophile looking for an exceptional listening experience, and don't mind having a cable or sacrificing wireless features. Also consider battery life and charging; the Pi7 S2 offers wireless charging and a 5-hour battery life as opposed to non-applicable in IE600 due to its wired nature. Give Feedback

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."

"If you've got the bucks, the Sennheiser IE 600 is a nice, upscale set of in-ear monitors made of a lightweight metal with an unusual texture. It comes with a suite of extras, and performs well at virtually every task."
