When deciding between the KZ ZSN Pro (with Mic) and the Sennheiser Momentum 4, consider the following: If price is a significant constraint, the KZ earbuds are notably less expensive. They are compact, easy to carry around, and come with an in-line mic, which is convenient for calls. However, for the best audio quality and immersive experience, especially with features like active noise cancellation and higher overall sound quality, the Sennheiser headphones are superior, albeit at a higher cost. The Sennheisers also offer advanced Bluetooth codec support like AptX Adaptive that may contribute to better sound quality during wireless use. If you frequently engage in activities like gaming or watching movies, the lower latency of the Sennheisers can enhance the experience. On the other hand, if portability and price are your primary concerns, KZ may be the better pick. Give Feedback

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."

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."
