*Plughz horse ear plugs effectively reduce loud, distracting noises which in turn helps to keep the horse focused. *They can be used for competition, trailering, clipping or in any situation your horse finds stressful. *The foam within the ear plugs is dense and has a better sound deadening effect than those made with sheepskin or acrylic. *The ear plugs mould to the horses ears and will not shake out.
