The Sennheiser HD 250BT is a wireless option with a strong performance in sound quality, low latency, and a long battery life, making it suitable for gaming and TV as well as music and calls. They are also sweatproof certified, making them a potential choice for exercise. The HD 400S, although slightly more expensive and wired, excels in comfort and includes a detachable cable. It doesn't support low latency, so it may not be as ideal for gaming or watching videos. Neither model has active noise cancelling, but both have sound isolation to some degree. If portability and wireless convenience are important to you, go with the HD 250BT; if you prefer comfort and don't mind a wired connection, the HD 400S could be the better choice. Give Feedback

"As a lightweight, robust audio provider with a long battery life, the Sennheiser HD 250BT offer a lot for their price: very good Bluetooth codecs, an app connection and an extremely understated design. These headphones may not be among the most comfortable, but they deliver adequate sound – without overdriving or distortion."

"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."
