ISOtunes Sport CALIBER Bluetooth Earbuds – Limited Edition

ISOtunes Sport CALIBER Bluetooth Earbuds bring electronic hearing protection and wireless audio together in a compact in-ear design. They offer an alternative to over-ear defenders for people who prefer earbuds.

Limited Edition In Blaze Orange

Hearing protection and environmental sound

Tactical Sound Control uses microphones to reproduce surrounding sounds while electronically limiting loud sound transmission. Physical controls let you adjust the listening level.

The manufacturer lists a 32dB SNR hearing-protection rating. Actual protection depends on correct fitting and use; this rating does not mean every sound is reduced by exactly 32dB.

Bluetooth music and calls

Bluetooth 5.2 connectivity supports music and phone calls from compatible devices. This adds everyday audio functions to the hearing-protection design.

When choosing electronic ear protection, consider how you intend to use both features. Comfortable listening and a reliable ear-tip seal are separate considerations, and both deserve attention.

Battery life and charging case

ISOtunes Sport CALIBER Bluetooth Earbuds provide up to 13 hours of Bluetooth use, or up to 16 hours using Tactical Sound Control alone. The rechargeable case stores two additional full charges.

Battery life varies with settings and use. Keeping the case charged helps ensure the earbuds are ready when needed.

Outdoor durability

The earbuds carry an IP67 protection rating. The supplied package includes a portable charging case, three pairs of ear tips, a USB-C charging cable and documentation.

Choosing and caring for your earbuds

Take time to select suitable ear tips and follow the supplied fitting instructions. Check their condition regularly and keep the manufacturer’s care guidance available.
