If you prioritize phone calls or video conferences and willing to invest more, the Koss Porta Pro with a mic is suitable for you as it offers the convenience of an in-line microphone. On the other hand, if you are budget-conscious and are looking for good sound quality in music, the KZ ZSN Pro can be a cost-effective choice, though you compromise on the added functionality of a built-in microphone. Keep in mind that the Koss Porta Pro has a classic open-back design which can provide a more natural listening experience, but it might let in more ambient noise and leak sound to your environment, whereas the KZ ZSN Pro has an in-ear design that offers noise isolation, which can be better for noisy environments.

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."

"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."
