Video: You can't exactly blast your favourite tunes when you're supposed to be listening intently to the baby monitor. This custom build from popular DIYer Ben Heck will let you listen to your music until your little one starts to make noise.
In this episode of The Ben Heck Show, Heck creates some adaptive headphones that can automatically switch between a music device, like your phone or MP3 player, and another sound input using an off-the-shelf baby monitor. The build requires some electronics know-how, as well as various circuits and other electronic components. But after you have it all assembled, you can crank up your music and without worrying about not hearing the baby. As soon as they make some noise, the channel will automatically switch over to them. Once things get quiet again, the music resumes.
