If you prioritize value and primarily listen at home, the HD 400S offers good sound, comfort, and is wired, which is great for zero latency listening but less portable. However, the Momentum Sport, while more costly, includes features like active noise cancelling for quieter environments, a sweatproof design for exercise, a higher quality build, and app customization options. For an active lifestyle and varied use including exercise and travel, the Momentum Sport is superior, including a heart rate monitor, but for strictly at-home use, especially for TV and gaming, the HD 400S would be more suitable due to its zero latency.

"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."

"We hadn't been expecting a new pair of dedicated sports buds but the surprise was nonetheless exciting. I got to try out the new buds at CES 2024 and while they have stayed true to delivering that "signature" Sennheiser sound, with a wide soundstage and strong sense of detail, it’s the extra wearable tech inside them that stands out to me against the best workout headphones."
