Small, light and convenient – the cordless Bluetooth® earplugs are your daily companion in the shop or on the construction site. It protects you from noise while you work and enables you to make telephone calls via Bluetooth® or listen to your favorite music in excellent sound quality. You don't have to do without the professional ear protection: loud ambient noise outside the safe sound level of 79 dB (corresponds to EU standard EN352) is blocked. Still want to know what's going on around you? Conversation mode takes care of that. The innovative technology allows speech and ambient noise to pass through at a safe listening volume – so you can still talk to your colleagues at any time without removing your ear protection. After the work is done, the earplugs are simply recharged in the charging case supplied.
