So the highly anticipated Bose QC45’s are finally here. Now overall the Bose QC45’s are a great pair of headphones to consider… but they really excel when it comes to their comfort. But today we’re going to see how the QC45’s stack up to the Sony 1000XM4’s… and I’m also going to lightly compare them to the Sony XB900N’s… cause the XB900N’s are on their way out cause the XB910N’s are finally here as well.
