The Bose 700 headphones are at a premium price and offer active noise cancelling, making them ideal for air travel and urban environments. They also have wireless capabilities with an impressive battery life, are optimized for both Android and Apple devices, and come with an app for controls customization. Conversely, the Sennheiser HD 400S are much less expensive and provide great value with excellent sound quality for music and higher performance for gaming due to their lower latency. They lack wireless connectivity and active noise cancelling, which limits their versatility compared to the Bose 700, specifically in louder settings or while traveling. Give Feedback

"Bose took active noise canceling and made it mainstream but eventually, the market caught up. Well, it seems like Bose was listening, because the Noise Canceling Headphones 700 is a complete redesign of its iconic product. The Bose Noise Cancelling Headphones 700 have a new design, improved sound quality, a touch-sensitive gesture pad for playback controls, and even USB-C charging."

"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."
