ISOtunes Caliber Noise-Canceling SNR: 32 dB In-Ear Bluetooth Hearing Protection

As the name suggests, the ISOtunes Caliber was designed specifically for hunters and sport shooters!

Powerful noise reduction (SNR: 32 dB) protects your hearing from gunshots.

At the same time, the earplugs amplify ambient sounds, allowing you to hear wildlife or understand your companions, for example!

Thanks to Bluetooth functionality, you can also use the ISOtunes Caliber as headphones—they deliver excellent sound quality when listening to music.

Of course, thanks to a built-in microphone with noise-canceling, they’re also ideal for phone calls!

Charging Case included

Thanks to Tactical Sound Control with SafeMax technology, the volume of the ISOtunes Caliber is limited to 85 dB to protect your hearing.

At the same time, ambient sounds are amplified, while sudden noises—such as a gunshot—are attenuated!

The in-ear earbuds’ housing is IP67-rated, making it dust-, sweat-, and water-resistant, so you’re prepared for even the harshest environments.

You can use the included charging case like a power bank to charge the ISOtunes Caliber!

The battery life for listening to music and making phone calls is approximately 13 hours (plus an additional 30 hours when using the charging case).
