Why you can trust What Hi-Fi?
These Sennheisers have been our Award-winning cans for two years on the bounce, but they've now been beaten by the Bose QuietComfort 15s, which sound better and are more adept at noise-cancelling.
But the PXC-450s remain a great buy. There's a volume control and a talk-through button on one ear, the latter silencing your tunes in one touch.
Sonically, they're dynamic and detailed – and smoother in the treble than the QC15s – but the Bose cans beat them for space and insight.
