Waterproof Acoustic Vents — for acoustic ports where waterproof sound transmission is essential. These vents give a double function—you need to have the acoustic elements inside protected from water and debris, but also from the standpoint of the clear uninterrupted experience. Over the years, these Waterproof Acoustic Vents have been adopted on thousands of portable electronic devices like smartphones, feature phones, digital cameras, sports cameras, smart watches, headphones or head-mounted displays and smart speakers/home-devices.
