The LKS-2 ListenTalk System operates on the 1.9 GHz unlicensed PCS band, utilizing Frequency-Hopping Spread Spectrum (FHSS) techniques for interference-free, full-duplex communication. This ensures crystal-clear audio, making it perfect for use in various settings, including classrooms, lecture halls, and meeting rooms.

The system's devices are designed with multiple layers of security, including a 40-bit group subscription, 32-bit authentication, and a 64-bit encryption scheme, enabling secure conversations.

The LKS-2 ListenTalk System is user-friendly, featuring Power, Talk, and Volume Up and Down buttons. It allows up to 10 simultaneous groups to operate in the same area, catering to larger gatherings. The devices are powered by a removable, non-proprietary rechargeable lithium-ion battery, with an optional compartment for 3 AAA alkaline batteries.

The system devices feature a 3.5 mm TRRS CTIA compliant headset connection, compatible with a standard electret style headset. They also have a built-in microphone with auto-detect circuitry, allowing users to use their personal earbuds if desired. The 64 x 128 OLED display with auto-dimming provides a clear view of all current statuses, including group name, volume levels, mute, battery status, time remaining, signal strength, unit ID, mode, and more.

The LKS-2 ListenTalk Base-8 System is not only a comprehensive solution but also an expandable one.
