If you prioritize portability and the ability to use earbuds during exercise, the Bang and Olufsen Beoplay EQ might be a better choice, as they are wireless, offer active noise cancelling, and are sweatproof. They also support a range of codecs such as AAC and AptX Adaptive for better compatibility with various devices. In contrast, the Sennheiser HD 400S are wired overhead headphones with a detachable cable, generally providing a more comfortable fit and better soundstage for an immersive audio experience. However, they aren't suitable for exercise and lack active noise cancellation, making them less ideal for noisy environments or traveling. Choose the Beoplay EQ for versatility and active lifestyles, or the HD 400S for stationary, immersive listening at a more affordable price. Give Feedback

"Bang & Olufsen’s audio products prioritize style and function just as much as sound quality. The company’s latest Beoplay EQ noise-cancelling true wireless earphones combine strong, accurate-leaning audio with solid noise cancellation in an exceedingly classy design."

"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."
