If you prefer earbuds that have a wireless design, active noise canceling for quieter environments, and are optimized for both Android and Apple devices with additional app support for sound customization, the Sennheiser Momentum True Wireless 2 would be a good choice, despite being significantly more expensive. They are better suited for travel, offer a longer battery life, and come with a microphone. However, if you're looking for a budget option and don't need wireless connectivity or active noise-canceling, the KZ ZSN Pro offers good overall sound quality and build with a cable that allows wired use, which might be preferable for stable audio connection and avoiding battery concerns.

"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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
