The Philips Fidelio X2HR offers a superior overall sound quality and a more expansive soundstage, making them better suited for an immersive music listening experience. However, this open-back design comes with lower noise isolation which is not ideal for noisy environments. Conversely, the Sennheiser HD 400S has an in-line microphone which can be valuable for calls and meetings. They have a closed-back design, offering better noise isolation, making them more versatile for use in varied settings. While the Philips models are typically much more expensive, they provide a more premium experience for critical listeners who prioritize sound quality over other features. 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."
