The Bose Quiet Comfort 45 headphones offer a premium listening experience with better noise cancellation, making them ideal if you highly prioritize a quiet environment to enjoy music or podcasts. However, they are significantly more expensive than the Sennheiser 450BT. On the other hand, the Sennheiser 450BT headphones provide good value for their price with decent sound quality and features such as AptX Low Latency, which is beneficial for watching videos or gaming due to reduced audio lag. They also boast a longer battery life than the Bose. Therefore, if cost is a major concern and you need headphones for activities that require low latency audio, the Sennheiser 450BT may be the better choice. Give Feedback

"If you want a set of wireless over-ear headphones you can put on, deploy noise-cancelling on your commute or at your desk and largely extinguish the outside world for up to 24 hours, the Bose QC 45 has the edge over most of the competition at the price."

"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."
