PU Foam Hourglass Earplugs – Engineered for All‑Day Comfort
Release Time：
2026-07-15
Extended exposure to noise demands hearing protection that remains comfortable for hours. PU foam hourglass earplugs feature a unique waist‑contoured shape that mirrors the natural curve of the ear canal, reducing pressure points and irritation during long shifts. This ergonomic design is particularly beneficial for workers with smaller ear canals or those who wear hearing protection continuously. Gold Dali’s hourglass earplugs use premium slow‑recovery foam that expands gently after insertion, creating a personalised seal with NRR values ranging from 29 to 35 dB. They comply with CE and ANSI requirements and are widely adopted in aviation, automotive manufacturing, and overnight travel applications. Gold Dali’s 14‑year history in foam processing ensures precise moulding and consistent performance. As industries place greater emphasis on worker comfort, hourglass earplugs are emerging as the preferred choice for prolonged wear scenarios.
