Fanvil HT302 QD to RJ9 Headset

Fanvil HT302 QD to RJ9 Dual-Ear Headset

The Fanvil HT302 QD to RJ9 Dual-Ear headset is a dual-ear, wired headset designed for desk phone users who need reliable audio performance in busy office environments. It connects via a standard RJ9 interface, making it compatible with the majority of RJ9-equipped IP desk phones. The HT302 ships as part of the Fanvil HT300 series alongside the mono HT301, and the two models share the same core audio architecture — differing primarily in ear coverage and weight.

Audio Performance

The HT302 delivers HD Wideband audio across both the speaker and microphone circuits. The speaker covers a wide frequency response range of 20 Hz to 20 kHz, which captures both the low-end warmth and high-frequency clarity of a caller’s voice. Speaker sensitivity is rated at 117 ± 3 dB, and speaker impedance sits at 32 Ω ± 15%. Input power handling is 10 mW, in line with standard passive headset design. Wideband speaker bandwidth ensures that calls processed over HD voice codecs are reproduced with full fidelity.

Microphone Design and Noise Handling

The HT302 uses a single omnidirectional noise reduction microphone. Its frequency response spans 50 Hz to 8 kHz — the full wideband capture range required for HD voice clarity. Microphone sensitivity is rated at -42 ± 3 dB, which is a standard pick-up level for close-talk boom microphones in this class.

The boom arm is 260° bendable, allowing the microphone to be positioned precisely relative to the speaker’s mouth. This flexibility, combined with passive noise cancellation support, helps reduce ambient background noise without requiring active electronics. The passive approach keeps the design simple and eliminates dependency on battery or USB power for noise filtering.

Physical Design and Build

The HT302 weighs 95 g in its dual-ear configuration. The mono HT301 variant weighs 73 g. Both models feature an adjustable headband for fit customisation. The cable extends to 1.8 m, giving the user sufficient reach from desk phone to workspace. The headset is finished in black and is rated to operate across a temperature range of -25 °C to 60 °C — a range that accommodates both air-conditioned offices and warmer field environments.

Connectivity

The HT302 uses an RJ9 connector, the four-pin modular interface found on the headset port of most traditional and IP desk phones. No adapter, dongle, or driver is required. Connection is plug-and-play on any RJ9-equipped handset socket.

Best Used By:

• Call centre agents and helpdesk staff — The dual-ear design isolates both ears from ambient noise, improving focus during high-volume call shifts. Wideband audio (20 Hz–20 kHz speaker, 50 Hz–8 kHz microphone) ensures callers are heard clearly across HD voice infrastructure.
• Reception and front-desk operators — The 1.8 m cable and RJ9 interface suit fixed desk phone setups. The lightweight 95 g build reduces fatigue during extended wear.
• Small office and SME users — The passive noise cancellation microphone works without external power. This suits environments where USB ports and amplifiers are not part of the desk phone setup.
• IT procurement teams standardising on Fanvil IP phones — The HT302 is a Fanvil-branded accessory. It pairs directly with Fanvil desk phones using native RJ9 headset ports with no compatibility configuration required.
• Budget-conscious buyers requiring wideband compliance — The HT302 delivers HD wideband audio at a passive headset price point. No active amplifier or digital signal processing unit is needed to achieve wideband performance.
