- Which is better for thick or curly hair?
- The Supersonic r. It includes a diffuser and its RFID attachments set airflow and heat for each styling job. The HD08 handles curls too, but you adjust settings yourself and a diffuser isn't listed among its five attachments.
- Is the Supersonic r worth the extra money?
- If you dry your hair daily or style for others, yes. You get half the weight, a longer cable, and attachments that configure themselves. For occasional use, the HD08 does the same core job for less.
- Which one is easier on the arm during long styling sessions?
- The Supersonic r at 317 g, less than half the HD08's 0.66 kg. Its curved wand shape also changes the balance point, which Dyson says reduces hand and arm fatigue.
- Can I use either one in the US?
- No. Both are rated 220-240V and neither is dual voltage, so they need a step-up converter on US 120V outlets. That voids most warranties, so buy a local-voltage version instead.
- Do both have intelligent heat control?
- Yes. Both use Dyson's heat control to measure airflow temperature and limit extreme heat. The Supersonic r adds attachments that set heat and airflow ranges automatically.
- Which one lasts longer?
- Dyson doesn't publish a lifespan for either. The Supersonic r has a filter designed for daily professional use and a longer cable, which suits heavy use. The HD08 has a long track record in home use.
