The Sennheiser HD 400S are wired, budget-friendly headphones that provide good sound quality; however, they lack wireless connectivity, which may limit your movement and device compatibility. If you prioritize mobility and the convenience of wireless listening, the Momentum 4 could be worth the investment. Conversely, if you are looking for value and do not need wireless functionality, the HD 400S would be a practical choice. 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."

"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
