H2 CZERWONE X-SHOCK H2-WHISTLE HUK Z GWIZDEM – F3 Bang Firecrackers, 20 Pieces
The H2 CZERWONE X-SHOCK H2-WHISTLE by Gaoo Fireworks is a pack of F3 category bang firecrackers designed for users seeking a distinctive combination of powerful reports and additional audible effects. Manufactured by the respected Gaoo Fireworks brand, this model is engineered specifically for those who desire more than a single sound effect from their firecrackers. Each piece in this pack features a strong bang (report) followed by, or accompanied with, a characteristic whistling sound, adding a unique dynamic to your pyrotechnic experience.
This product is supplied in a practical pack containing 20 firecrackers with a total NEC of 40 g per pack. Characterised by fuse ignition, these classic bang firecrackers stand out in the F3 category, which is reserved for pyrotechnic products intended for outdoor use in larger open spaces and is subject to stricter age and usage regulations. The X-SHOCK H2-WHISTLE is not a rocket, cake, or fountain—it is dedicated exclusively to delivering a short and strong acoustic effect, enhanced by a whistling prelude or accent.
With CE certification in category F3, safe and responsible use—according to the manufacturer’s instructions and all relevant regulations—is essential. These firecrackers are aimed at adult enthusiasts, collectors, and all users with experience in responsible handling of higher-category pyrotechnics.

What Effect Does H2 CZERWONE X-SHOCK H2-WHISTLE Produce?
Each firecracker delivers a sharp, strong bang (report effect) that is preceded by, or combined with, a high-pitched whistling sound. This dual-effect profile makes the product distinctly different from standard single-bang firecrackers. The whistle builds tension and anticipation before the main acoustic report, giving a more dynamic and attention-grabbing sound performance. There are no additional colour or flash effects; the emphasis is entirely on the auditory experience.
What Should You Consider When Choosing These Firecrackers?
When selecting F3 bang firecrackers like the X-SHOCK H2-WHISTLE, always pay close attention to the official CE certification and product category. F3 classification means the firecrackers are for outdoor use only, in large, open spaces, and may only be used by adults familiar with advanced pyrotechnics. NEC (Net Explosive Content) per pack is a useful parameter for comparing strength and quantity; in this case, 40 g per 20 pieces. However, loudness and sound characteristics also depend on design, construction, and effect type—not NEC alone.
The presence of an additional whistling effect distinguishes this model from standard bang-only firecrackers and provides a layered, unmistakable acoustic signature. Always follow the manufacturer's instructions for fuse ignition, observe minimum safety distances, and comply with all legal requirements for storage, transport, and use.
This product is suitable for users who wish to enhance their display of cakes, rockets, fountains, or other firework assortments with a strong sound accent. It is not intended for use as a visual firework; if you require coloured or flashing visual effects, consider complementing your purchase with appropriate pyrotechnic items.
