We have 3 kids. When they all play Tablet we feel like in the middle of a fair. Is this familiar? Headphones to the rescue? But if they produce over 85 dB they will harm your kids' hearing! Special headphones for kids? Wired headphones for kids may not always meet the limit and their wireless counterparts are expensive and they emit EM radiation. Use "Voli" instead! Get $1 headphones and cap your kids tablet volume with "Voli". Test your setup decibels! We tested "Voli" to be under 85 dB on devices around. But we recommend you borrow a decibel meter to check your setup before using with your kids.
