If you are looking for more natural and spacious sound, the Koss Porta Pro tends to offer a wider soundstage, which is great for music but it lacks noise isolation due to its open design and may not be ideal for noisy environments. Conversely, the KZ ZSN Pro provides better noise isolation and build quality, making them more suitable for travel and public places. Comfort is comparable between both, but the Porta Pro is more portable due to its foldable design. If you frequently make calls, the ZSN Pro has a slightly better mic. Consider that the Porta Pro is significantly more expensive than the ZSN Pro, which could influence your decision if budget is a concern. Give Feedback

"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."
