The Bowers and Wilkins Pi5 S2 are wireless earbuds with active noise cancelling, a comfortable fit, and built-in controls, making them a good choice for exercise, travel, and casual listening sessions. They have a decent battery life, with additional charges provided by the case, and also support wireless charging. If you frequently make phone calls or require a built-in microphone, the Pi5 S2 would be beneficial. However, they're more expensive. The Etymotic ER2SE, on the other hand, offers excellent sound quality and exceptional noise isolation at a lower cost, but they lack features like active noise cancelling, wireless connectivity, and a microphone. These are wired earbuds that are more suited for critical listening and situations where sound fidelity is highly prioritized over convenience features. Their comfort might be an issue for some, and they aren't designed for active use. Give Feedback

Major HiFi

Chris Golembeski | January 2023
"Bowers and Wilkins isn’t looking to make an obscure, premium wireless bud catered specifically towards audiophiles. Instead, it seems apparent that they’re going for the crown: a cool and popular look, an easy and comfortable fit, and an engaging stage with a great balance that is perfectly suited for mainstream listeners and audiophiles alike."

Sound Guys

Lily Katz | April 2022
"Etymotic isn’t playing around: it takes audio seriously and has mastered the art of the noise-isolation earphone. Sure, the fit of the earbuds looks silly but it’s a signature Etymotic thing and could be considered charming by some. If you’re looking for best-in-class audio for a realistic price, the ER2SE is it."
