Sony’s MDR line of Bluetooth headphones sold like gangbusters during Black Friday, but if you were holding out for noise cancelling models, Amazon’s rewarding your patience today with the biggest discount ever on the top-of the line MDR1000x.

These headphones have all the features you’d expect in a good pair of Bluetooth headphones these days: NFC pairing, 20+ hour battery life, and even LDAC Hi-Res audio compatibility. But the secret sauce here is noise cancellation, including a special mode that lets ambient voices through either at all times, or just when you cup a hand over the right earcup. $228's still a solid chunk of change, but it’s rare to see these dip below $300, let alone this low.
