If you prioritize wireless connectivity and active noise canceling, the JBL Live 670NC would be a better fit, especially for travel with its longer battery life and convenience features like ear detection. Despite being pricier, they provide the flexibility to use them wired as well. However, if budget is a major concern and you don't need wireless capability, the Sennheiser HD 400S offers very good sound quality and comfort for a typically much less expensive price, which makes them suitable for longer listening sessions. These are wired, over-ear headphones and lack active noise cancellation, which is an important consideration if you're often in noisy environments. 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."
