If wireless convenience and noise cancelling are priorities for you, the JBL Tune 660NC would suit you better, also offering built-in controls and better suitability for air travel due to their active noise cancelling feature. However, if you prioritize sound quality for tasks like music, gaming, and calls, and prefer more comfort for extended use, the Sennheiser HD 400S may be the better option, especially considering they are often significantly less expensive. Both have a closed-back design for passive noise isolation, but the Sennheisers have a reputation for better build and sound quality, while the JBLs provide the convenience of both wireless and wired usage. Keep in mind that neither is particularly well-suited for exercise, but the JBLs do have longer battery life for wireless use. Give Feedback

"The JBL Tune 660NC is the best value you can get from a set of on-ear headphones. There's no companion app so you don't get many additional features, but everything the JBL Tune 660NC sets out to do, it does well. At this price, the JBL Tune 660NC is an easy recommendation for on-ear headphone lovers"

"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."
