The Sennheiser FLEX 5000 digital radio frequency wireless system with 3.5 mm jack is designed to provide flexible and reliable wireless communication. The FLEX 5000 uses digital technology and operates on free radio frequency bands, ensuring low interference and high stability.

The device consists of a transmitter (TX) and receiver (RX) that can be configured to operate in mono or stereo mode. The transmitter has a 3.5 mm jack input to connect audio device output (e.g., a microphone or CD player) and can be powered by AAA batteries or an external power source. It also offers several advanced features, such as interrupt management and the ability to set dedicated channels. The system is compatible with Sennheiser’s proprietary Audio Frequency Shift (AFS) audio encoding protocol, which ensures high audio quality and low latency.
