If you prioritize portability and a built-in microphone for calls, the Koss Porta Pro with mic would meet those needs, whereas the Sennheiser HD 250BT offers a potentially longer battery life and may have better build quality. The Koss is on-ear and typically provides a more open soundstage, but may be less comfortable for long listening sessions compared to the around-ear design of the Sennheiser, which can also offer better noise isolation. The Sennheiser might also have more modern features such as Bluetooth 5.0 and aptX Low Latency codec, which are great for video and gaming due to reduced audio lag. 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."
