Is the Dyson Supersonic Straight+Wavy worth $526.50?

Only if you will use the diffuser and smoothing attachments often. The dryer itself is fast and light, but the price is high against the standard Supersonic, which does the same core job.

How is it different from the standard Supersonic?

The dryer is the same Supersonic body; the bundle adds attachments for straight and wavy hair, including a diffuser. If you already own a Supersonic, buying the attachments separately may cost less.

What is the maximum temperature?

It is capped at 176°F. That is lower than many dryers, which is meant to reduce heat damage but can mean slower drying on very thick hair.

What comes in the box?

Expect the Supersonic dryer, a diffuser and straight/wavy styling attachments, plus the usual nozzles. Check the listing for the exact attachment set before buying.

The best new price seen is $526.50 at mercari.com as of November 5, 2026. With only 2 stores listing it new, watch for restocks and bundle discounts rather than deep markdowns.
