Bose SoundSport Free Truly Wireless Bluetooth Headphones (Black) $199 Delivered @ Amazon AU
Good time to get yourself a Christmas present!
These review pretty well. If you don't need active noise cancellation, it'd probably be a better buy than the Sony WF-1000XM3s at $100-140 less. They're also IPX4 rated so you can safely wear them during exercise or in the rain, unlike the Sonys.
