1. Ergonomic neck design for maximum comfort: Our tinnitus infrared earplugs are specially designed for a comfortable fit that adapts to the neck curve. This keeps your hands and the lightweight construction does not affect your daily activities. Wear it anytime and enjoy the soothing red light radiation. 2. Promotes blood circulation in the ears: Thanks to the innovative red light therapy with a 650 nm wavelength, the red light penetrates deep into the capillaries of the ear canal. This procedure aids microcirculation, relieves discomfort, and improves sleep quality through photobiostimulation while reducing inflammation. 3. Flexible gear settings for individual comfort: The infrared earplugs offer three adjustable modes. The second gear activates fast laser flashing, while the first gear features slow flashing, and the third gear provides continuous lighting. Adjust the settings to suit your preferences. 4. Extensive accessories: The earplugs come with three pairs of silicone ear tips (S or M or L) and silicone nose covers.
