If you're on a budget and need earbuds for a variety of activities like exercise or commuting, the JBL Tune Flex might be a better choice as they are significantly less expensive. While both provide very good sound quality, the JBL has low latency mode which is useful for gaming, but their noise isolation and call quality are just fair. On the other hand, Sennheiser Momentum Sport, although more expensive, offers better features for active users such as sweat and water resistance, active noise cancelling, and health tracking capabilities. If call quality is important for you, Sennheiser's are also superior. Choose Sennheiser if you prioritize features and overall quality and are willing to invest more. Give Feedback

Gabby Bloch | May 2023
"JBL is offering a similar design and arguably better resolution than the more expensive AirPods 3rd Generation. Add to that a comfortable and versatile fit, an equalizer and pretty decent ANC, and you’ve got a quality wireless earphone. I would have loved longer battery life and more crystal calls, but for the price, you can’t complain. A solid deal overall."

"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."
