Considering the tradeoffs, if wireless functionality and active noise cancelling are important for your usage, the 1More Sonoflow would be the better choice, despite being somewhat more expensive. They are suitable for a variety of use cases including music, exercise, and travel, with fairly good noise isolation and long battery life. Conversely, if you prioritize sound quality and are looking for a budget-friendly option primarily for indoor use like calls, meetings, gaming, and TV, the wired Sennheiser HD 400S might suit you better. They also score higher for comfort, and have a good built-in mic for calls. Give Feedback

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

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."
