Good review Vince - but are you able to actually compare with the QC25 or similar?  I notice this phrase "In all honesty, I’ve lost the urge to pick up a pair of Bose QC series headphones." Does this mean you've actually heard the QC15 or 25.  I have the 25's.  They are incredible. The Cleer cancellation must be incredible if its on par or better.  The Cleer seem to be a bit on the warm, bassy side?

Nice review! I've tried a friends QC25, and while they were quite good, there was something a bit off with the sound signature when NC was on, IIRC.. These might be interesting!
