What are they? A super-premium and extremely stylish way to cut yourself off from the world.
The sophisticated styling, futuristic controls and clear, detailed sound was all well and good but the noise-cancelling technology fast became my favourite feature.
Distracting office chatter all but disappeared and the H8's passed the aeroplane test with flying colours, eliminating horrendous engine noise almost entirely and allowing me to settle comfortably into my in-flight movie with the volume set at an appropriately ear-safe level. I never want to fly without them again. Which is unfortunate as the review pair got returned last week...
But how do they sound? Damn good. Which, to be honest, is what you expect after paying a premium price for a premium product from a premium hi-fi company like B&O.
The sound was well balanced and detailed with no obvious colouring. The high end wasn't harsh or overpowering and there was plenty of bass to head-nod along to. The sound was pleasingly warm and I never suffered any ear fatigue.
