If gaming is a priority, the Razer Hammerhead True Wireless earbuds, with their low latency game mode, are suitable and cost-effective, whereas the Sennheiser Momentum Sport offers better build quality and advanced features like heart rate and body temperature tracking, optimized for fitness enthusiasts. If you make a lot of calls or attend meetings, both offer very good mic quality but Sennheisers may provide a slight edge in sound quality. Sennheiser's earbuds support high-quality codecs like AptX Adaptive, which is great if you desire premium audio fidelity and have a compatible device. However, if you're on a budget and need earbuds mainly for casual use, the Razers would be sufficient and wallet-friendly. Give Feedback

The Verge
Chris Welch | August 2019
"This latest set is more “Pro” than not in both looks and features: they offer active noise cancellation, a low-latency gaming mode, and have switched to a in-ear design with silicone tips. Just like many of the company’s laptops and gaming accessories, the 2021 Hammerhead True Wireless include Razer’s full Chroma RGB system. It makes for what Razer calls “the ultimate wireless earbud flex.”"

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."
