If you prioritize exceptional sound quality and a wide soundstage for an immersive listening experience, especially for music at home in a quiet environment, then the Sennheiser HD800S, with its open-back design, would be a substantial investment. However, they're not suitable for noisy environments due to their open-back design providing minimal noise isolation. On the other hand, the KZ ZSN Pro with a mic offers a good balance of sound quality and functionality at a budget price. Its in-ear form factor and closed-back design provide better isolation from ambient noise, making them a versatile choice for use on the go or during exercise. Additionally, the presence of a microphone makes them handy for calls. Keep in mind, though, the KZ ZSN Pro may not match the comfort or expansive sound experience provided by the Sennheiser HD800S when listening in quiet spaces. 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."
