The Bose QuietComfort Ultra Earbuds are pricier, but they offer superior overall sound quality, better comfort, and enhanced noise isolation compared to the Sennheiser 450BT, making them excellent for immersive music experiences and air travel. However, the Sennheisers are better for calls and have a longer battery life, plus they have a wired option which might be helpful if you often forget to charge your devices. The Sennheisers are also more durable and have a foldable design for easier storage. If budget is a concern and you need versatility for different activities including gaming and TV watching, the Sennheiser 450BT is a solid choice. Give Feedback

"Bose put the time in to fix the major issues with the previous earbuds, and the Bose QuietComfort Ultra Earbuds are very befitting of its price point. While you might be tempted to save a few bucks and go with the Bose QuietComfort Earbuds II on sale, fight the urge. There are enough upgrades here to justify the newer model."

"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."
