SF Series HD Speakers

Declared standards

Certification and batch labels should be verified on the delivered product and packaging. Use only standards declared for the exact product, size and market.

Care basics

• Clean the shell with mild soap and water only.
• Air-dry the liner away from direct heat.
• Do not modify, drill or repaint the shell.
• Replace after a significant impact even if damage is not visible.

How it should feel

New cheek pads should feel snug and move the skin when the helmet moves. The helmet should not rotate freely, create a concentrated pressure point, or obstruct vision.

Fit checks

1. Measure horizontally above the eyebrows and around the widest point.
2. Start with the chart; model shape and hair can affect fit.
3. Wear the helmet for 10–15 minutes indoors before removing labels.
4. Confirm the retention strap can be correctly secured.
