Our Verdict
Bose QuietComfort 25/QC25
Bose QuietComfort 45/QC45 Wireless
The Bose QuietComfort 45/QC45 Wireless are better over-ears than the Bose QuietComfort 25/QC25. While both headphones have a very comfortable fit and are well-built, the QC45 are wireless headphones that block out more bass-range noise like bus and plane engines and have longer-lasting continuous battery life. However, some users may prefer the QC25's wired AAA battery design, as you can easily replace the battery when it can't hold a charge anymore.
