If you are on a budget and still want good quality audio, the KZ ZSN Pro may fit your needs, while maintaining enough comfort for extended use. They are significantly less expensive, come with a detachable cable, and are somewhat portable. However, if you prioritize top-notch sound quality with an expansive soundstage and you listen in a quiet environment, the Sennheiser HD800S could be well worth the investment. They boast superior comfort and overall sound quality, but at a significantly higher price point. Both are wired and do not support wireless connectivity, which is important to consider if you require mobility. Additionally, neither pair comes with a microphone, meaning they may not be the best for taking calls or meetings. Keep in mind the Sennheiser HD800S is less suited for outdoor activities due to their open-back design and lack of isolation compared to the more exercise-friendly KZ ZSN Pro. 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."
