The Beats Studiobuds are well suited for use during exercise thanks to their sweatproof design and wireless form factor, offering convenience and a more modern stemless shape. They feature active noise cancelling, making them a good choice for air travel or environments where you need to block out ambient noise. The Sennheiser HD 400S, being wired over-ear headphones, will provide a more comfortable fit and better soundstage suitable for gaming and activities requiring extended periods of wear. If you prefer convenience and portability for active use and can justify the higher price, go for the Beats. Conversely, if you prioritize comfort, soundstage, and a more budget-friendly option, the HD 400S would be a solid choice. Give Feedback

"For less than the price of the AirPods, the Beats Studio Buds delivers a good fit, great sound, and active noise cancellation. This is also the first set of Apple-owned Beats earbuds to feature quick pairing with Android devices, albeit at the expense of some key features for Apple users."

"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."
