Binaural RJ-9 headset with a noise-cancelling microphone that filters out 90% of background noise for clearer landline calls
The Spracht ZUMRJ9B is a binaural headset designed for landline and desk phones from most major brands. It connects through a wired RJ-9 interface with an inline smart cord that adapts to many phone models. Broadband audio support delivers a more natural sounding voice during calls. This headset suits office workers and call-centre staff who spend long hours on the phone.
An over-the-head frame holds two earcups fitted with leather and foam cushions for comfort and durability. The binaural stereo design covers both ears to help the user focus on the conversation. A noise-cancelling microphone filters out 90% of background noise so the caller hears clear speech. The wired connection removes the need for batteries or charging during the workday.
Users moving from a monaural headset gain stereo coverage that reduces fatigue during extended sessions. Replacing a standard handset frees both hands for typing or note-taking while the broadband audio improves voice clarity. The jump is worth it when background noise is high and the 90% noise-cancelling microphone makes a noticeable difference. It is not for users who need wireless mobility or a USB connection for softphone applications.

The RJ-9 plug connects only to deskphone headset ports, so the headset cannot be used with PCs, mobiles or USB devices without a separate adapter.
The dual-ear cups and adjustable headband require enough desk clearance for the frame to rest over the head and both ears simultaneously.
Plug the RJ-9 connector into the deskphone headset jack, not the handset jack, then route the cord so the inline controls sit within easy reach.
