If you value wireless freedom and the convenience of built-in controls with a premium build quality, go for the Sennheiser Accentum Plus; they also support a lossless codec and active noise cancelling which are great for immersive listening and travel. However, if cost is a concern and you don't mind a wired connection without active noise cancelling, the HD 400S is significantly more affordable and still offers very good sound and comfort. Keep in mind that the Accentum Plus provides a better experience for calls and gaming due to its low latency and mic quality. Give Feedback
