If you're on a budget and mostly listen to music wired, the KZ ZSN Pro could be suitable with its good sound quality and excellent build, but it lacks wireless convenience, active noise cancelling, and features like sweatproof certification for exercise. The Sennheiser Momentum Sport, while more expensive, offers very good wireless sound quality, advanced features like heart rate tracking, active noise cancelling, and is optimized for sports with a sweatproof design. It's better for an active lifestyle and varied use-cases but comes at a premium price. Give Feedback

"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."

Amelia Schwanke | January 2024
"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."
