Every pair of Decibullz is different. These moldable earphones can be customized to fit any ear just right.

Dip the thermo-plastic earpiece in hot water, then mold them to comfortably match your ears. Re-do, if necessary. You’ll have an earphone that fits and that won’t fall when you run, jog, bounce, or even cartwheel.

In fact, Maker and gymnastics coach Kyle Kirkpatrick wanted all-terrain earphones that’d stay put even while jumping off a trampoline. Kyle went on to invent the first pair of custom fit earphones.

He has expanded beyond regular earphones to Bluetooth ones, and noise-blocking earplugs—all of which secure to your ear and isolate sounds. Each pair of Decibullz is tailored just for you.
