If you're on a budget and mainly use wired connections for listening, the Sennheiser HD 400S would be a good choice, though its lack of wireless capability limits its use in mobile scenarios. These headphones are comfortable and provide good sound quality, but are not ideal for exercise due to their form and lack of sweat resistance. On the other hand, the Sennheiser Momentum True Wireless 4 are more expensive but offer the convenience of wireless listening with excellent sound quality and active noise cancelling. They also have a long battery life, are sweatproof, and are more suited for use during exercise, calls and meetings, or travel. However, if you're looking for immersive gaming or TV experiences, the low latency and virtual surround features of the True Wireless 4 make them superior. The True Wireless 4 is also more portable, coming with a charging case that supports wireless charging, enhancing their convenience for users on the go. Give Feedback

Headphone Dungeon
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."

"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
