ISOtunes Sport Caliber Hearing Protection

The ISOtunes Sport Caliber are Bluetooth-equipped earbuds that pack a lot of features into a tiny package. They are dust, sweat, and waterproof, and the run time is approximately 13 hours between charges. In addition to the charge that the earbuds themselves carry, the storage case also holds a further power reserve, and it can recharge the earbuds twice before needing to be recharged. This means that you don’t have to worry so much about being near a mains power supply to keep the earbuds topped up.
The built-in microphones can react to and block out gunshot noise in under two milliseconds while allowing safe sounds to actively pass through. The earbuds block out 32dB of noise, reducing harmful sound levels to make them safer and more comfortable.
As well as blocking potentially harmful noise levels, the earbuds can also amplify other environmental sounds, like range instructions, so that you remain fully aware of your surroundings. Hard-to-hear sounds can be amplified up to eight times, so you can actually improve your sensitivity to lower-level noise while completely protecting yourself against harmful levels.
In addition to protecting your hearing, the earbuds are also equipped with Bluetooth so that you can take phone calls or listen to music while wearing them.
With easy-to-operate controls, a high level of protection, the facility to amplify low-level noise, and Bluetooth connectivity, ISOtunes has packed a lot of fantastic features into these tiny buds, and although not cheap, they are very effective and offer good value.
