Many great bands, from Lynyrd Skynyrd to Cage the Elephant, have two important things in common: The founders met in high school and are four times more likely than the general population to suffer from hearing loss. So if you — or your offspring — plan to form a band this school season, now is the time to thing about hearing health. It is easy to prevent but very difficult to repair or treat.

Eardials are smart earplugs that filter the sound hitting your ears so you can listen to live music at a volume less damaging to your hearing. They are small and transparent so you don’t look like a dork wearing them and made of soft silicone so they aren’t uncomfortable. The earbuds monitor your ambient sound level and display the decibel levels around you in real time on the phone app. It will tell you to move when the decibel levels are too high and how long you can stay where you are before you risk irreparable damage. They also come in a cute aluminum case that clips to your key chain so you actually have them with you.
