No, but we used to be able to!
Mute Switch P/N 43548-01 (DISCONTINUED)
THIS IS WAS A PUSH TO MUTE SWITCH!
Please note that the in-line mute switch (PN 27708-01) offers a soft, click-over mute rather than a momentary mute (push-to-mute). This in-line mute switch is only compatible with H-series headsets.
