If budget is a significant concern, you may prefer the HD 400S for its noticeably lower price and better value. These headphones provide a decent sound quality and are particularly comfortable, which is great if you listen for long periods. However, they are not wireless, so if freedom from cables is a priority, you might like the Momentum True Wireless 2, despite the higher cost. The True Wireless 2 also offers noise cancellation, and these earbuds are better suited for exercise and travel due to their portability and sweatproof feature. Keep in mind that only the Momentum has app support that allows for sound customization. Give Feedback

"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."

"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
