Seems like a good price for true wireless extra bass version. Harvey Norman has blue colour for $199 and black for $379
These were $250 last month: OzB post
Some more products with amazing discounts:
Sony WH-XB900N Wireless Over-Ear Extra Bass Headphones with Noise Cancelling $249, was $499
Sennheiser Momentum True Wireless Headphones $249, was $499
Same at Sony, still only for blue
