This is the WH-1000XM5, Sony's over-ear noise cancelling pair, and we sell it as it comes — nothing rebadged and nothing repackaged. The listing we stock is the one with the hard case in the box rather than the soft pouch, which is the difference worth knowing about before you compare prices. The noise cancelling runs on four microphones on each earcup, eight in total, and an optimiser that re-reads your surroundings rather than applying one fixed setting.
That is the part that matters on a plane or an open-plan floor, where the noise is not the same at minute forty as it was at minute one. Sound is carried over LDAC, so a phone that supports it sends more data to the headphones than standard Bluetooth allows. The drivers cover 20 Hz to 40 kHz.
Whether you hear the top of that is another question, but the range is there and the file is not being thrown away on the way over. The battery is quoted at 30 hours. Three minutes on a USB-PD charger gives about three hours of playback, though that charger is sold separately and is not in the box.
Bluetooth 5.0 holds two devices at once, so a laptop call does not mean unpairing your phone first. They weigh 250 grams, the earcups are round and faux leather, and there is no water resistance rating at all — these are for the commute, the desk and the flight, not the gym. In the box: the headphones, the collapsible hard case, a USB-C cable and the documentation.
