Calmer Kids
Flare Audio
Small in-ear devices that reduce the frequencies most associated with noise-related stress, rather than blocking sound the way conventional earplugs do. Marketed by Flare Audio for sound sensitivity, autism, hyperacusis and misophonia. Not hearing protection for loud environments -- see Alpine Muffy Kids or Ems for Kids for that.
Typical price: $1 to $1
