SoundGear Custom Molded Platinum devices have 4 distinct memory modes to toggle through. The first memory (Normal) delivers amplification equally across all frequencies. The second (High-Frequency Boost & Max Wind Management) boosts higher frequency sounds like the whistling wings of ducks overhead and has an algorithm that will detect wind noise and send a counter signal to drastically reduce it. This will help people who have an existing high-frequency hearing loss hear better, but also work well for clarity of sound on those windy days in the field. The third Memory (Telecoil) helps you effectively communicate on a telephone and the fourth memory (Mute) is used to mute or turn off your device. Each pair of SoundGear custom devices also comes standard with a removable lanyard system.
