If you're looking for earbuds that are better suited for exercise and sports, with advanced features like heart rate and body temperature tracking, go with the Sennheiser Momentum Sport. They also support a high-quality lossless codec, have a slightly longer battery life, and come with accessories for a secure fit. However, if you prioritize noise isolation, such as for air travel, and prefer more straightforward earbuds without the need for sports integration, the Bowers and Wilkins Pi5 S2 would be a better option. While they both have good sound quality, Sennheiser offers slightly better microphone quality, which could be important for calls. Neither is ideal for gaming or TV due to latency, but Sennheiser's lower latency might provide a slightly better experience in those areas. 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."

"We hadn't been expecting a new pair of dedicated sports buds but the surprise was nonetheless exciting. I got to try out the new buds at CES 2024 and while they have stayed true to delivering that "signature" Sennheiser sound, with a wide soundstage and strong sense of detail, it’s the extra wearable tech inside them that stands out to me against the best workout headphones."
