The KZ ZSN Pro earbuds are a budget-friendly option that provide good sound quality and comfort with a sturdy build, although they're not the best for calls and meetings or high-movement activities like exercise. They have a detachable cable and come with ear hooks to help secure them in place, but they're not wireless, sweatproof, or noise cancelling. In contrast, the Sennheiser HD600 headphones are a premium choice with exceptional overall sound quality and soundstage, which make them excellent for music and TV, but they are pricier, bulkier, and not as portable or suited for use during exercise or travel. They have an open-back design for a more natural listening experience, though they do not isolate noise well, which may not be ideal in noisy environments. Neither have features like app equalization, wireless capabilities, or active noise cancelling. Choose the KZ ZSN Pro for a more affordable, solid listening experience or the Sennheiser HD600 for top-notch sound quality in a quiet environment, keeping in mind the cost and portability considerations.

David Becker | 2019
"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."
