CALIBER from ISOtunes Sport is a true wireless Bluetooth earbud built specifically for the range and the hill, combining music and calls with certified electronic hearing protection. Its Tactical Sound Control™ technology uses omni-directional microphones to amplify quiet environmental sound — footsteps, voices, a dog working ahead — while reacting in under two milliseconds to suppress a gunshot report before it reaches harmful levels. The earbuds carry a certified 32dB SNR hearing protection rating to EN 352 and are built to IP67 standard, fully dust-tight and able to withstand submersion, so weather and recoil are no concern. A single charge runs up to 13 hours in Bluetooth mode or 16 hours with Tactical Sound Control active, and the compact charging case holds two further full charges for a long day away from the mains. Bluetooth 5.2 pairs to two devices at once, switching automatically between calls and music. Finished in a distinctive orange for easy spotting in a kit bag, CALIBER comes complete with its charging case, a USB-C charging cable and a variety pack of eartips for a secure, personal fit.
