The ISOtunes Sport CALIBER Earbuds.

Offering true wireless freedom, the CALIBER earbuds store in a charging case that provides two full charges. However, with 13-hour Bluetooth capability, the earbuds will provide a full day of use on a single charge. Also, they have an automatic power-off function after two hours of no Bluetooth connectivity to prevent unintended battery loss.

While on the range or on the hunt, Tactical Sound Control Technology provides 8x hearing enhancement. As a result, you can hear your game walking through the woods, or hear the range master call range commands. This is also particularly useful for firearms instructors that want to hear their students during range time.

Likewise, SafeMax Technology limits volume output to 85 dB and can protect users from high-impact noises in under 2 milliseconds. Correspondingly, the earbuds are 25 NRR tested and approved to ANSI s3. 19-194.

Finally, there is no need to worry about dust or sweat negatively impacting your earbuds. With IP67 durability, they are completely waterproof and dust-tight. As a result, the CALIBER earbuds can be immersed in just over 3 feet of water for 30 minutes and still function perfectly.

ISOtunes Sport CALIBER comes with three pairs of ISOtunes TRILOGY Short Eartips (S, M, L), three pairs of ISOtunes TRILOGY Tall Eartips (S,M,L), 1 pair of silicone eartips, a charging case, charging case lanyard, and USB-C charging cord.
