If you prioritize call quality and plan to use your audio device in noisy environments or for air travel, the Sennheiser HD 400S would be a better choice due to its superior microphone and noise isolation. However, if you're more interested in an affordable option for general music listening and gaming, the KZ ZSN Pro (with Mic) is a great value and provides excellent sound quality for its lower price point. The KZ ZSN Pro is also more portable and suitable for exercise due to its earbud form factor. In contrast, the Sennheiser HD 400S headphones offer a more comfortable over-ear experience and a more immersive soundstage, making them ideal for extended listening sessions and TV viewing.

"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."

"Sennheiser has done it again. The HD 400S performs well beyond its price range and is one of the better budget model headphones I’ve tried. It has very few bells and whistles and offers a simple means of listening that still delivers amazing clarity and quality. If you need a good first pair of headphones or need something that you can take out of the house, then the HD 400S is definitely for you."
