It’s an admirable performance at this price range, but B&W is right to acknowledge its weaker noise cancelling. To be fair, the Pi6 does a respectable job of blocking out the deep rumble of an aircraft engine – it’s not quite in the same league as some of its noise-cancelling rivals, but it’ll still come in handy on a long-haul flight. However, our second test reveals that it’s far less effective at dealing with the more varied sounds of a busy airport, with voices and higher frequencies leaking through quite noticeably. Frequent fliers who require really effective noise cancelling when they’re travelling should perhaps look elsewhere, but if you just want a high-quality set of earbuds at a competitive price then the Pi6 is good value for money
