Bose QuietComfort 35 II/QC35 II Wireless 2018 vs Bose QuietComfort 45/QC45 Wireless

The Bose QuietComfort 45/QC45 Wireless are the next generation of the Bose QuietComfort 35 II/QC35 II Wireless 2018, although they don't offer much of a significant improvement over their predecessor. Both headphones are similarly well-built and have very comfortable fits. They also have comparable battery performances. However, the QC35 II can block out slightly more background noise in the mid to treble ranges and support NFC pairing. On the other hand, the QC45 have SimpleSync, a feature that allows you to pair the headphones up to other compatible Bose headphones, speakers, and soundbars to share their audio.
