same with the Soft Pink Q35's, the white Q45's were never on sale and always around $190 when the other two colors were $153.
black Q45 has been as cheap as $149 in this recent deal with bonus anker powerbank. https://www.ozbargain.com.au/node/834058
this time it's the otherway around with just white on sale. white headphones are a nice change I got white headphones recently and they look great. one other thing to know is apparently white plastic products can change colour a bit (become like milky) from years of sun exposure so be aware of that if you plan to use them a lot outdoors.
I keep mine in a cheap case from amazon and its been 1 year with zero colour change. the Q45 just like the Q35 comes with a hard case included in the box.
Thanks OP! I got one.
