If you are on a budget and prefer wired earbuds with good overall sound quality, comfort, and the ability to use with a detachable cable, the KZ ZSN Pro X is a suitable choice. If you don't mind spending more, value a wireless experience, and are looking for earbuds with very good sound quality, comfort, and built-in microphone for calls, as well as features like low latency mode for gaming, the Razer Hammerhead True Wireless would be better. The Razer is also sweatproof and comes with an app for customization, which the KZ lacks. However, if you are concerned about battery life, the Razer offers less typical use time per charge compared to the continuous wired use of the KZ. Give Feedback

Jasper Lastoria | April 2023
"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."

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.”"
