If you value portability and the convenience of wireless earbuds for use during exercise or while on the move, the Razer Hammerhead True Wireless will suit you well, plus they have a low latency mode great for gaming. However, if your priority is sound quality and comfort for extended listening periods, the Sennheiser HD 400S headphones are the better option. While the Sennheiser lacks built-in controls and is wired, their over-ear design may offer a more immersive experience for TV, music, and book/podcast listening. Keep in mind, the Razer Hammerhead is more expensive, but they come with features like sweatproof certification and game-focused enhancements. Give Feedback

"This latest set is more “Pro” than not in both looks and features: they offer active noise cancellation, a low-latency gaming mode, and have switched to a in-ear design with silicone tips. Just like many of the company’s laptops and gaming accessories, the 2021 Hammerhead True Wireless include Razer’s full Chroma RGB system. It makes for what Razer calls “the ultimate wireless earbud flex.”"
"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."
