Fanvil Ht310 Rj9 Mono Headset

I couldn’t find a specific spec sheet for a Fanvil HT310 model, but based on Fanvil’s HT300‐series headsets it’s likely a wired professional headset designed for office and call‐center use with these typical features: Wired connectivity (likely RJ9 or USB depending on variant) for direct connection to phones or PCs. Wideband HD audio for clearer voice quality on calls. Noise‐reducing microphone (often passive or ENC technology) to help cut background noise. Adjustable boom mic and comfortable headband/ear cushions for all‐day wear. Inline controls (answer/hang up, mute, volume) and a lightweight ergonomic design.
