The Bose Quiet Comfort 45 offers leading comfort and excellent noise isolation, making them ideal for air travel and noisy environments. They also provide a consistent wired connection. On the other hand, the Sennheiser Momentum 4 boasts superior overall sound quality, better microphone quality, and significantly longer battery life, which makes them well-suited for both music enthusiasts and gamers, as well as for extended TV and video sessions. Both models provide similar control features and are optimized for both Android and Apple devices, but if active noise cancelling and supreme comfort are your priorities, go with the Bose; for sound and battery life, choose the Sennheiser.

"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."

Sound Guys
Christian Thomas | January 2023
"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."
