If budget is a concern and you're mostly interested in listening to music and making calls, the JBL Live 670NC could be a better choice since it provides good overall sound quality and comfort, with the added benefit of active noise cancelling for frequent travelers or noisy environments. However, if you're an active individual or need features suited for exercising, the Sennheiser Momentum Sport, with its sweatproof and dustproof design, secure fit silicone fins, and health tracking integration, might justify the higher price. It also offers better sound quality, especially for gaming or TV, and supports a low latency codec, which is great for minimal audio delay. Give Feedback

"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."
