If you prioritize wireless connectivity and longer battery life for convenience, the 1More Sonoflow with its wireless option and 40 hours of battery life will serve you well, but it comes with a higher price. Additionally, if you travel a lot, its active noise cancelling feature can provide a more isolated listening experience. In contrast, if you're looking for affordability and a focus on music quality, the KZ ZSN Pro would be a cost-effective choice with its good sound quality; however, it lacks a microphone and wireless functionality which could be drawbacks for calls and portability. Both offer similar comfort and soundstage, but the Sonoflow has an app for equalization customization, which is missing in the ZSN Pro. Give Feedback

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

"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."
