Hypoallergenic silicone earplugs specifically for office work. They are intended for those who work in an office environment with other colleagues where conversations and noises from office machines and phones distract your attention and concentration. These earplugs do not isolate you completely from the surrounding environment, so you can hear when your phone rings or someone calls you. They are easy to install and suitable for prolonged use. They reduce noise by 26dB and have a ventilation filter. The package includes an aluminum carrying case.
