Bluetooth/Radio Connectivity

New Advanced Safety Listening Technology ( SLT )

The Safety Listening Technology helps the users to listen to ambient sounds while wearing hearing protection. Listening to the ambient sound includs natural listening and auditory strengthening listening. Sound reproduction output is limited to a maximum of 82 dB to prevent damage to hearing.

Ambient-Dependent Technology ( ADT )

Ambient-Dependent Technology introduces an advanced listening feature: It allows the user to adapt and optimize the environmental listening function to different scenarios by switching mode.

• Mode 1: Observation

Highest volume and widest frequency response to maximize hearing. To be used when the user is still over watch, hide spot, stop to listen, etc.

• Mode 2: Vigilance

High volume with reduced high frequencies to limit sounds such as footsteps on gravel, grass moving under feet, equipment moving on body.

• Mode 3: Conversation

Maximizes the frequencies important for face-to-face communications for the natural speech while lowering the frequencies outside of the average speech band.

• Mode 4: Comfort

Low volume and narrow frequency response to be used when in noise for long periods of time (vehicle, air transport) where environmental listening is not prioritized over communications and overall comfort.

Acoustic Metamaterials ( AMM )

To meet customer’s high attenuation requirement, ZeroPlus engineer worked several years on material. Acoustic Metamaterials is a new material discovered by ZeroPlus team and applied on hearing protection products. Acoustic Metamaterials can manipulate and control sound waves in ways that are not possible in conventional materials. It could not just achieve high attenuation, it could also be adjusted the noise reduction frequency according to difference use environment. Especially with good performance on low frequency noise reduction.

Control Via Mobile Application ( APP )

With the APP, users can adjust the volume, customize the equalization, change listening modes, and adjust noise reduction according to their needs.

Multi-Radio Technology ( MRT )

Multi-Channel Communication System

• Supports up to 8 devices simultaneously transmitting data and voice.
• Unlimited number of receiving devices can participate.
• Ideal for complex communication environments due to its efficiency, reliability, and flexibility.
• Enhances multitasking and advanced communication strategies.

Multi-Stage Relay Technology

• Extends signal transmission distance and improves coverage.
• Devices act as relays to progressively forward the signal.
• Overcomes limitations caused by distance and physical barriers.
• Expands the overall signal coverage area.

Full Duplex Radio

• Simultaneous sending and receiving of data.
• No need to switch between modes.
• Reduced delays and waiting times.
• Analogy to natural conversation.
