The Freedom You Want. The Protection You Need.
CALIBER is a Bluetooth shooting earbud that packs a big punch in a little package. This electronic ear pro protects against dust, sweat, and water and can run up to 13 hours without needing to be recharged. The completely cordless design allows you to move freely while Tactical Sound Control™ delivers amplified natural sound and gunshot noise reduction.
Tactical Sound Control
TSC™ level-dependent technology allows safe sounds to actively pass through the product while blocking harmful gunshot noise. TSC™ protects hunters and shooters while giving them the ability to communicate, hear range commands, and listen for game.
25 dB of Noise Reduction
Most gunshots will register between 150 - 170 decibels. At those levels hearing damage can occur quickly. Combat those dangerous noise levels and shoot safely all day long.
IP67 Durability
Tough on gear? Now you don't need to worry. CALIBER is completely waterproof and dust-tight. Plus all ISOtunes Sport products are backed by a 1-year warranty.
NRR 25
An NRR of 25 means that the hearing protection is estimated to reduce noise levels by an average of 25 decibels across various frequencies.
'NRR' in hearing protection stands for 'Noise Reduction Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the NRR value, the greater the noise reduction level is considered to be.
NRR is primarily used as a rating system in North America, while Europe often uses 'SNR' (Single Number Rating) and Australia/New Zealand use 'SLC80'; which both differ slightly in calculation.
