If price is a major factor, the Sennheiser 450BT headphones are less expensive and have a respectable overall sound quality. They provide a comfortable over-ear fit, have a foldable design for portability, and their longer battery life makes them suitable for extended listening sessions. For an active lifestyle or if you prefer a stealthier look, the Momentum True Wireless 3 earbuds are lightweight, have higher sound quality, better build quality and controls, and come with additional ear tip sizes to ensure a secure fit. However, consider that the Momentum earbuds are pricier and have shorter battery life compared to the 450BT headphones. Both models have active noise cancellation and are optimized for both Android and Apple devices, but the Momentum earbuds have a slightly better microphone quality which might be useful for calls.
