ISOtunes Sport's Defy Slim Basic is an ultra-slim electronic earmuff built for the range and the field, without Bluetooth or streaming to complicate it. Tactical Sound Control amplifies ambient sound so you can still hear what's going on around you, then cuts off gunshot-level noise in under two milliseconds to protect your hearing on the shot — SafeMax technology caps the amplified output at 85dB so you're not risking damage over a long day. It's SNR 27 rated, tested and approved to ANSI S3.19-1974, and at just 289g it's noticeably lighter than most electronic earmuffs, with a slim profile that sits comfortably against a rifle stock for a clean cheek weld. Two AAA batteries (included) give up to 300 hours of use, and an IPX4 rating means sweat, rain and dust won't put them out of action. Finished in camo for the field rather than the range.
