If you prioritize portability and a built-in microphone for calls, the Koss Porta Pro with mic would be a beneficial choice for on-the-go use and phone conversations. These are lightweight and can be folded, making them very travel-friendly. However, if you prefer over-ear headphones with a focus on sound isolation and a potentially more neutral sound signature, the Sennheiser HD 400S might be more suitable. They can offer a fuller listening experience, especially in quieter environments. Consider how and where you'll likely use your headphones most, as this may guide your decision between these two options. Give Feedback

"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."
