Last month we looked at Bose's wireless QuietComfort 35 noise-canceling headphones ($350) and came away with the feeling that – at least for those willing or able to test premium waters – Bluetooth-based audio fulfillment was finally a possibility. So it would be remiss not to turn next to rival premium headphone maker and well-regarded German audio company Sennheiser to see what it has to offer in the wireless noise-canceling space. Sennheiser has dipped its toes into the NC market before with the PXC 250-ii, PXC 450, and its lauded wireless Momentum series, but the firm announced its flagship PXC 550 travel cans ($400/£330) in an almost direct response to Bose's QuietComfort transition to Bluetooth, which makes comparisons here inevitable. First though let's look at the design and features of the PXC 550 headphones on their own terms.
