ABOUT THE SORDIN SUPREME SERIES

The Sordin Supreme series consists of electronic hearing protectors developed primarily for hunting, recreational shooting, and professional applications where protection against hazardous noise must be combined with environmental awareness. The series incorporates active electronic technology that allows users to hear important ambient sounds while maintaining protection against harmful noise levels.

A defining characteristic of the Supreme family is its level-dependent sound reproduction system. External microphones capture sounds from the surrounding environment and reproduce them through speakers inside the ear cups. This allows users to communicate, detect nearby movement, and remain aware of warning signals without removing their hearing protection.

When the surrounding noise reaches potentially harmful levels, the electronic system limits reproduced sound while the ear cups continue to provide passive attenuation. This combination is particularly useful during hunting and shooting activities, where quiet environmental sounds and sudden high-intensity gunfire may occur in rapid succession.

The series emphasizes compact ear cup construction, comfortable headband designs, and practical outdoor durability. The low-profile cups help reduce interference with rifle stocks, while the sealing cushions provide a protective fit around the ears.

Different Supreme models offer various electronic functions and comfort configurations. Selected models feature advanced audio profiles, additional lighting functions, or alternative headband and cushion designs.

Through its combination of passive attenuation and electronically controlled ambient sound, the Supreme series provides hearing protection for users who need to remain attentive to their surroundings.

ABOUT THE SORDIN SUPREME PRO

The Sordin Supreme Pro is an active electronic hearing protector developed for hunting, recreational shooting, and shooting range applications. It combines certified passive noise attenuation with electronically controlled ambient sound amplification, allowing users to maintain awareness of their surroundings while protecting their hearing from hazardous noise.

The earmuffs provide a certified Single Number Rating (SNR) of 28 dB and a Noise Reduction Rating (NRR) of 21 dB. These values describe the hearing protector's noise attenuation performance according to different testing standards. Actual protection depends on correct fitting, cushion condition, and the quality of the seal around the ears.

A distinguishing feature of the Supreme Pro is its level-dependent electronic hearing protection system. External microphones continuously capture environmental sounds, which are then reproduced through speakers inside the ear cups. This allows users to hear conversations, footsteps, animal movement, and other relevant acoustic signals without removing their hearing protection.

The system incorporates directional sound reproduction, helping users identify the location of sounds in their surroundings. This is particularly useful during hunting, where the ability to recognize the direction of approaching wildlife or other movement can contribute to better situational awareness.

Quieter environmental sounds can be electronically amplified, making them easier to hear in relatively quiet surroundings. This functionality supports communication between hunters and helps maintain awareness of subtle acoustic signals that might otherwise be difficult to distinguish while wearing conventional passive earmuffs.

When the surrounding noise increases, the electronic system automatically controls the reproduced sound level. Sordin specifies that sound delivered through the level-dependent function is limited to a maximum of 82 dB. The passive attenuation provided by the ear cups continues to protect the ears independently of the electronic amplification system.

The Supreme Pro features high-quality internal speakers designed to provide clear and natural sound reproduction. This helps preserve the character and direction of environmental sounds, making conversations and other important acoustic information easier to recognize.

Volume and electronic functions are controlled using accessible push buttons positioned on the earmuffs. The controls are designed for straightforward operation, including during outdoor activities where users may be wearing gloves.

The earmuffs incorporate a compact, low-profile ear cup design. This is particularly important when using hunting rifles and shotguns, as large hearing protectors can interfere with the shooter's cheek position against the stock. The reduced cup profile helps maintain a more natural shooting position.

The 75302-S configuration features green ear cups combined with a leather-covered headband. The headband distributes pressure across the head, while the adjustable suspension allows the earmuffs to be positioned according to the user's head size and shape.

The Supreme Pro is supplied with PVC foam sealing cushions. These provide a seal around the ears to support passive noise attenuation while maintaining wearing comfort. Sordin also offers compatible GEL sealing cushions as an optional accessory for users who prefer a different cushioning material.

The manufacturer specifies efficient attenuation even when wearing glasses. Nevertheless, the effectiveness of the seal can be influenced by the shape and thickness of spectacle frames, making correct positioning important for maintaining adequate hearing protection.

The Supreme Pro features an IP67-tested construction, with waterproof microphones and a protected battery compartment. These features help maintain reliable operation when the earmuffs are exposed to rain, humidity, and other challenging outdoor conditions. Proper closure of the battery compartment is important for maintaining the specified protection.

Another practical feature is the 3.5 mm AUX audio input, which allows compatible external audio equipment to be connected to the hearing protector. This can include communication radios and other audio sources equipped with a suitable connection.

A 3.5 mm mono audio cable is included for connecting compatible equipment. This allows users to receive audio through the internal speakers while retaining the hearing protector's level-dependent ambient sound functionality.

The electronic system is powered by two AAA batteries, providing an operating time of up to 400 hours under suitable conditions. Actual battery life depends on the intensity of ambient sound amplification and the use of external audio functions.

To reduce unnecessary power consumption, the Supreme Pro incorporates an automatic switch-off function. If no control button is operated for four hours, the electronic system switches off automatically. This is particularly useful when the earmuffs are accidentally left powered on after use.

The device also provides a low-battery warning when approximately 40 hours of operating time remain. This allows users to replace the batteries before an extended hunting trip or shooting session.

The Supreme Pro weighs approximately 314 grams without batteries and 339 grams with batteries. Its relatively low weight and compact construction make it suitable for prolonged use during outdoor shooting and hunting activities.

The combination of an adjustable headband, protective cushions, and compact ear cups helps distribute pressure comfortably while maintaining the seal required for effective noise attenuation. The hearing protector can also be folded for more convenient transportation and storage.

The Sordin Supreme Pro is particularly suitable for hunters who need to hear conversations and environmental sounds while remaining protected from gunfire. Its electronic amplification is also useful on shooting ranges where communication and situational awareness are important.

With its combination of 28 dB SNR attenuation, directional sound amplification, 82 dB electronic sound limitation, IP67-tested construction, and long battery life, the Sordin Supreme Pro provides a practical hearing protection solution for hunting, shooting, and other activities involving intermittent hazardous noise.
