Flare Audio Calmer Mini lets you hear sound without distortion. It utilises a patent pending waveguide technology to soothe stressful sounds, helping you feel less sensitive to harsh resonance. Whether you're commuting, at concerts, or just walking in busy environments, you'll get less unwanted noise everywhere you go. All without muffling sound. Unlike traditional ear plugs, Calmer Mini changes the shape of your ear canal and concha, reducing frequencies (between 2kHz - 8kHz) that create distortion. The small, silicone design sits in your ear without adding stress or pressure, so you can wear in comfort for hours without fatigue. The results are obvious. High definition sound when you're listening to music or out on the move. Calmer Mini are perfect for anyone with sensitive hearing - including those who suffer with hypersensitivity associated with autism, Hyperacusis, Misophonia, and other hearing conditions.
