A neighbour is noisily tearing down one of its office blocks. I'm sure a new unpretty office block will then be noisily built in its stead, so I bought a Bose QC15 to work in peace meanwhile.
Summary review: It handles the construction-related noise well, but it does really badly with respect to human noises such as a telephone conversation or a crying baby.
Both of the employees I spoke to in the Bose shop here in Munich were sloppy, arrogant and ignorant. Not a good combination. I walked out, and bought the QC15 at Hifi Concept instead.
