The Sennheiser HD 400S headphones, being over-ear and closed-back, offer better sound quality and are more comfortable for long-term use, which makes them suitable for focused music listening and calls or meetings. However, they don't perform as well during exercise due to being less secure and not sweatproof. On the other hand, the Youthwhisper Bone Conduction headphones are designed for activity with a secure fit and sweatproof feature, making them more appropriate for use during exercise, but with a tradeoff in overall sound quality and noise isolation. The bone conduction design allows you to remain aware of your surroundings, which can be safer during outdoor activities. If you prioritize immersive music and call quality, go for the Sennheisers; if you need headphones for active use and situational awareness, the Youthwhisper might be the better choice.

Jim | August 2022
"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."

The sound quality is great for this style of headphones, and it has many other cool features."
