Both the black and white models of the latest Bose QuietComfort Ultra Headphones are currently on sale at Myer's for $552.46 (can also price match with JB Hi-Fi if you prefer or easier to click + collect). These are currently the best active noise cancelling headphones as per RTINGS.com's listings / reviews.
Can highly recommend - excellent for long haul international flights.
Ultra quiet or ultra comfort 🤔
