Was looking to buy these for my sister and found them on Amazon at what looks like very close to the all time best prices shown on 3Camels.
Silver also available for $217.34
Violet also available for $217.00
Looks like the same model numbers on Amazon as those shown on the comparable Officeworks pages so if the deal is still live in the morning you could try for a price beat at Officeworks if you're not in lockdown.
Edit: Price on black dropped by $1.00 and silver increased by $0.17
Sound etc is good but constantly falling out of my ears.
Can't get a good fit with any of the ear bits.
