Poly Blackwire C435-M Binaural Wired Headset

Poly Blackwire C435-M Binaural Wired Headset

The Poly Blackwire C435-M is a lightweight, modular USB headset designed for PC-based calls, video conferencing and multimedia. Its convertible design allows it to be used as a binaural stereo headset or changed to a monaural configuration, providing greater flexibility for different working and listening preferences.

Convertible Mono or Stereo Design

The Blackwire C435-M includes a modular second earpiece, allowing users to choose between binaural stereo audio and a single-ear configuration. Stereo mode provides audio through both ears for calls, music and multimedia, while mono mode helps users remain more aware of activity around them.

Discreet Over-the-Ear Wearing Style

Rather than using a conventional overhead headband, the C435-M features a compact over-the-ear design. Its low-profile appearance makes it suitable for video meetings, PC telephony and mobile professionals who want a less prominent headset.

An optional neckband kit can be purchased separately for users who prefer a behind-the-head wearing style.

Wideband Voice and Stereo Multimedia Audio

Wideband voice support helps produce clear, natural speech during compatible calls. For music and multimedia, the headset provides stereo output across a wider frequency range, while Dynamic EQ automatically adjusts the sound profile according to whether the user is speaking or listening.

Noise-Cancelling Boom Microphone

The boom-mounted noise-cancelling microphone is designed to reduce surrounding background sound before it reaches the listener at the other end of the call. Enhanced digital signal processing further supports natural-sounding voice communication.

Convenient In-Line Call Controls

The in-line control unit provides quick access to commonly used call functions without requiring the user to return to the softphone window.

• Answer or end supported softphone calls.
• Increase or decrease listening volume.
• Mute or unmute the microphone.
• View in-line indicators for supported call and mute states.
