The KZ ZSN Pro, being significantly less expensive, is a wired option with good build quality and sound quality satisfactory for music and TV. They're also suitable for air travel and have a detachable cable, adding to their durability. The Razer Hammerhead True Wireless, with higher build and sound quality, is especially better for gaming due to low latency and provides better mic quality for calls. They're convenient for exercise, being sweatproof and wireless, with added benefits like app customization and a compact form factor for portability. However, the Razer's wireless nature commands a higher price and you have to consider battery life for ongoing use. Give Feedback

David Becker | 2019
"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."

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.”"
