Hearing Aid Ear Cover This is an analog hearing device that you wear over your ears to collect sound. Stored in a non-smoking, pet-free environment. Words are easier to understand! "Watashi no Mimi" (My Ears) does not use electricity and assists hearing through resonance. It was very convenient to use this at concerts and when listening to music, as the sound became louder. You can hear musical instruments better (this is just my personal opinion). Disinfected with ethanol before shipping. Shipping via Yu-Packet Post Mini.
