ISOtunes® Sport Introduces CALIBER Earbuds for Uncompromising Protection

Carmel, IN – For hunters and shooters who want hearing protection without sacrificing situational awareness, ISOtunes Sport is excited to debut its innovative CALIBER earbuds. Tactical Sound Control™ technology allows for listening for ambient sounds such as game movement or range commands while ears remain protected from gunshot noise.

The true wireless earbuds are equipped with Bluetooth 5.2 for hands-free hearing protection without any cords to get caught on guns or gear, and an IP67 rating safeguards against water and debris damage. They boast a longer battery life than the competition with 13 hours of Bluetooth capability.

ISOtunes Sport CALIBER earbuds come with a carry case that can charge for up to 25 hours, foam and silicone eartip options, and a USB-C charging cable.

ISOtunes Sport products protect and enhance hearing with innovative options for sport shooters who demand safety without sacrificing performance. To learn more about CALIBER and browse the full ISOtunes Sport lineup, visit
