If price is a major consideration, you would lean towards the Sennheiser 450BT as it's less expensive and offers very good build quality, excellent noise isolation, and is suitable for long flights due to its excellent battery life and comfort. However, if you're looking for earbuds with the latest technology, superior sound quality, and additional features like lossless audio streaming, sweat and dust resistance, and active noise cancelling, then the Momentum True Wireless 4 is worth the extra cost. The Momentum also offer better suitability for exercise, and they come with a case that provides additional battery life and supports wireless charging, unlike the 450BT headphones. Give Feedback

Sound Guys
Lily Katz | March 2022
"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."

What HiFi
Andy Madden | January 2024
"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."
