The Bowers and Wilkins Pi5 S2 earbuds might be preferred for their portability and suitability for exercise owing to their sweatproof design and smaller size compared to Sennheiser Momentum 4 headphones. They also support wireless charging and have a generally good sound quality. However, the Sennheiser Momentum 4 headphones offer superior active noise cancelling, longer battery life, and higher mic quality, which could be better for calls and meetings. If having a great immersive experience for music, gaming, and video is a priority, along with comfortable wear for extended periods, Momentum 4 is the stronger option. Consider the Pi5 S2 for affordability and convenience, or the Momentum 4 for premium sound quality and features. 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."

Christian Thomas | January 2023
"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
