When choosing between the Sennheiser 450BT and the Sennheiser Momentum 4, consider that while the 450BT is more affordable, the Momentum 4 likely offers superior sound quality, comfort, and additional features such as noise cancellation. If comfort and sound are top priorities and your budget allows, the Momentum 4 might be the better choice. But if you are looking for a more cost-effective option that still delivers the Sennheiser audio experience, the 450BT should suffice for general use. Keep in mind that the Momentum 4 may also offer longer battery life and a more premium build quality, which might be worth the extra cost in the long run. Give Feedback

"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."

"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
