The Razer Hammerhead True Wireless earbuds are more wallet-friendly and may appeal to gamers due to their low latency game mode, but if you prioritize audio quality and comfort for extended listening sessions, the Sennheiser Momentum 4 headphones are superior, with better sound quality and comfort ratings. The Momentum 4 also offers active noise cancelling, a feature not available in the Razer Hammerhead, making them better suited for air travel or noisy environments. Furthermore, the Momentum 4's over-ear design might provide a more immersive experience, yet they are less portable than the compact Razer earbuds. Both options have good microphone quality, but the Sennheiser's longer battery life could be a deciding factor for those who dislike frequent charging. 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.”"

Christian Thomas | January 2023
"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
