Wired stereo headset for calls

The Jabra BIZ 2300 QD Duo is a wired stereo headset built for voice communication. Its binaural, supra-aural design covers both ears to help users focus in busy offices or contact centres. The 3.53 ft cable connects via a Quick Disconnect plug for compatibility with desk phones and adapters. Frequency response spans 150 Hz to 4.50 kHz, tuned for speech clarity.

Quick Disconnect fitting and cable care

Installation is a matter of plugging the QD connector into a compatible cord or amplifier; no drivers are required. The short 3.53 ft cable reduces tangles but limits reach, so the desk phone or adapter must sit close to the user. Common issues include accidental disconnection if the QD latch is not fully seated and cable strain when the headset is pulled beyond its slack.

150 Hz to 4.50 kHz voice band

The 150 Hz to 4.50 kHz response range is the specification that decides suitability. It covers the core frequencies of human speech but does not extend to full-range audio, so the headset is not intended for music playback or multimedia entertainment. Buyers needing wider bandwidth for media should consider other models.

Questions about this item

How can I confirm the Jabra BIZ 2300 QD Duo is delivering the 150 Hz to 4.50 kHz frequency range after I plug it in?

Play a test tone sweep covering the 150 Hz to 4.50 kHz range; both earpieces should reproduce the low and high limits clearly without distortion.

What comes in the box with the Jabra BIZ 2300 QD Duo and what must I purchase separately?

The headset with its 3.53 ft cable and Quick Disconnect plug is included; a compatible QD cord or direct-connect cable for your desk phone or softphone is sold separately.

Should I choose the Duo stereo version or a mono model for my open-plan office?

The Duo binaural stereo version covers both ears for better focus in noisy spaces; choose a mono model only if you need one ear free for ambient awareness.
