The AKG K712 Pro is a premium option with a wider soundstage and higher overall sound quality, particularly suited for an immersive listening experience in music and TV. However, it is open-back, which means it leaks sound and doesn't isolate noise well, making it not ideal for noisy environments. The Sennheiser HD 400S, while less expensive, provides good sound quality, a closed-back design for better noise isolation, and an integrated microphone that makes it more suitable for calls and meetings. It's also more portable due to its foldability. If budget is a concern and you need versatility for different uses including better isolation, the Sennheiser HD 400S is a solid choice. If you prioritize top-tier sound for home use, especially in quiet environments, and you're willing to invest more, the AKG K712 Pro excels. 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."
