The EPOS PC38X is a strong choice for gaming due to its excellent microphone quality and low latency, making it ideal for engaging in multiplayer games where communication is key, and has an open design which is typically preferred for an accurate soundstage. However, the open design also means it won't isolate noise well, which can be an issue in noisy environments. On the other hand, the Sennheiser Momentum 4 offers active noise canceling and a closed design, which is better for listening in noisy settings like air travel or commuting. It also has wireless capabilities with a long battery life, making it more versatile for on-the-go use. The Momentum 4 is more expensive, but if wireless use and noise isolation are important to you, it might justify the cost. Additionally, the Momentum 4 has an integrated microphone which is less prominent than the boom mic on the PC38X, giving it a sleeker look for everyday use. Give Feedback

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."
