Title: Needs volume control
Review: We thought these were the other "night vision" goggles by Wild Planet, which my son had tried on, and liked.This item gets one star because the 'earbud' did nothing but give off high-pitched very loud feedback noises. My ears were ringing after trying to get it to work. There was no volume control, so if a kid has it in their ear and a dog barks nearby or the feedback persists, I worry that it could damage their hearing. If it had volume control, I'd give it 2.5-3 stars.
